Answer:

[tex] \orange{ \boxed{ \sf{ ( \: {x}^{2} + 11x + 18 \: ) \: sq. \: units}}}[/tex]

Solution :

Lenght = x + 9

Width = x + 2

[tex] \sf \green{area \: = \: (x + 9)(x + 2)} \\ \sf \green{ = \: { {x}^{2} + 11x + 18}} [/tex]

Answer:

[tex]x^2+11x+18\: \sf(square\:units)[/tex]

Step-by-step explanation:

To use the area model of solving multiplication and division problems, calculate the area of each of the colored rectangles and add them together.

Area of a rectangle = Length × Width

Area of blue rectangle:  [tex]x \times x = x^2[/tex]

Area of pink rectangle:  [tex]x \times 9 = 9x[/tex]

Area of green rectangle:  [tex]2 \times x=2x[/tex]

Area of orange rectangle:  [tex]2 \times 9=18[/tex]

Area of entire rectangle = blue + pink + green + orange

                                        = [tex]x^2+9x+2x+18[/tex]

                                        = [tex]x^2+11x+18\: \sf(square\:units)[/tex]

a) Points shown in blue

b) correlation is negative since the y-values decrease as the x-values increase.

c) Line of best fit needs to have the same number of points above as below.

[tex]============================[/tex]

First, let's use the Slope Formula to find the slope:

[tex]\pmb{\displaystyle\frac{y2-y1}{x2-x1} }[/tex]

[tex]\pmb{\displaystyle\frac{4-1}{3-0} }[/tex]

[tex]\pmb{\displaystyle\frac{3}{3}}[/tex]

Which simplifies to

[tex]\pmb{1}[/tex]

So the slope is 1.

Now, here's a point that the line passes through:

(0, 1)

Write the equation in point-slope form:

[tex]\pmb{y-y1=m(x-x1)}[/tex]

y-1=1(x-0)

Answer:

30 feet

Step-by-step explanation:

Area of a triangle = bh/2

A = bh/2

240 = b(16)/2

480 = (16)b

30 = b

Base = 30 feet

I hope this helps!

Answer:

30 ft

Step-by-step explanation:

Formula to find the area of a triangle is :

Area = [tex]\frac{1}{2}[/tex] × base × height

Given that,

Area of the triangle = 240 ft²

Height = 16 ft

Base = ??

Let us find now.

Area = [tex]\frac{1}{2}[/tex] × base × height

240  =  = [tex]\frac{1}{2}[/tex] × b × 16

240 × 2 = 16b

480 = 16b

Divide both sides by 16.

30 ft ⇒ base

Answer:

[tex]\rightarrow \boxed{\sf{8x+16}}[/tex]

Step-by-step explanation:

You have to isolate the term of x from one side of the equation.

Distributive property:

A(B+C)=AB+AC

5x+(x+12)+(2x+4)

5x+(x+12)+(2x+4)=5x+x+12+2x+4

5x+x+12+2x+4

Group and combined like terms.

5x+x+2x+12+4

Add the numbers from left to right.

12+4=16

Rewrite the problem down.

5x+x+2x+16

Then, you solve.

5x+x=6x

6x+2x=8x

8x+16

As a result, the final answer is 8x+16.

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

The answer is 20 (I think)

Step-by-step explanation:

The question says 6 tomato seeds at $2

So, 10*2=20

hence proved

The distance of the sailboat from the island at this time will be 131.78 miles.

The distance of the sailboat from the island will be calculated by using the law of cosines. This will be:

a² = (18 × 4) + 200² - (2 × 72 × 200 cos 15°)

a² = 72 + 200² - (144 × 200 cos 15°)

a = 131.78 miles.

The angle that should be used by the sailboat to correct its course will be:

= 180° - (sin 15°/131.78)

= 180° - 22.95°

= 157.05°

Answer:

240 cm³

Step-by-step explanation:

Volume of prism= base area ×height

The base is a rectangle here, and its area has the formula of length ×breadth.

Given

length of base= 10 cm

breadth of base= 6 cm

height of prism= 4 cm

Base area

= 10(6)

= 60 cm²

Volume of prism

= 60(4)

= 240 cm³

Answer:

240 cm³

Step-by-step explanation:

Volume of a rectangular prism: l*w*h

V = l*w*h  <== substitute the numbers (above) for the variables

V = 10*6*4

V = 60*4

V = 240 cm³ (cubed)

==================================================

Explanation:

First we need the slope

[tex](x_1,y_1) = (-4,2) \text{ and } (x_2,y_2) = (3,-5)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{-5 - 2}{3 - (-4)}\\\\m = \frac{-5 - 2}{3 + 4}\\\\m = \frac{-7}{7}\\\\m = -1\\\\[/tex]

Then we can find the y intercept using the coordinates of (x,y) = (-4,2)

y = mx+b

2 = -1(-4)+b

2 = 4+b

2-4 = b

-2 = b

b = -2

Alternatively, you can use the other point (x,y) = (3,-5) and m = -1.

Because m = -1 and b = -2, we go from y = mx+b to y = -1x+(-2) which simplifies to y = -x-2

Answer: 25.1

Step-by-step explanation:

1. Find the radius of the inner circle

(the formula for the circumference of a circle is )   C =2pi r

To find the radius of the inner circle, you would plug in the given information so that your equation looks like this:

22 = 2(22/7)r

then solve for r

r = 3.5

2. add 4 to the radius of the inner circle

3.5 + 4 = 7.5

3. find the circumference of the outer circle using 7.5 as the radius

22 = 2 (22/7) 7.5

C = 47.1

4. Subtract the circumference of the inner circle from the circumference of the outer circle

47.1 - 22 = 25.1

Step-by-step explanation:

tbh I don't know I need help with that too please like this comment

The measure of the marked central angle of the sector will be 280°.

Let r is the radius of the sector and θ be the angle subtended by the sector at the center. Then the arc length of the sector of the circle will be

Arc = (θ/2π) 2πr

The figure addresses 7/9 of a complete circle. Then the arc length of the circle will be given as,

Arc / P = 7/9

Simplify the equation, then we have

(θ/2π) 2πr / 2πr = 7/9

θ/2π = 7/9

θ = 14π / 9

θ = 280°

The central angle of the sector will be 280°.

Based on the intersecting secants theorem, the value of x is: B. 30.9°

The intersecting secants theorem states that when two secants intersect, the measure of the angle they form is half the difference of the intercepted arcs.

Thus, based on the intersecting secants theorem, we would have the following:

x = 1/2(138 - 76.2)

x = 1/2(61.8)

x = 30.9°

Answer:

Rise/Run (A)

Step-by-step explanation:

The slope of a line measures the steepness of the line. Most of you are probably familiar with associating slope with "rise over run". Rise means how many units you move up or down from point to point. On the graph that would be a change in the y values. Run means how far left or right you move from point to point.
