Multiply and write in standard form: 10x + 3)(2x - 1) Show all work

Answer:

-1/2; take both points which equals to -1/2

Step-by-step explanation:

In every triangle the addition of all internal angles is always 180 degrees.

So this means we can build this equation

5x + 35 + 60 = 180

now separate x values and numerical values

5x = 180 - 60 - 35

x= (180 - 60 - 35)/ 5 = 85/5 = 17

ANSWER

The percent error is 10.9 %

EXPLANATION

The percent error is:

In this problem, the approximate value is 16 and the exact value is 14.25:

Answer:

10.9%

Step-by-step explanation:

14.25/16 = 0.890625

0.890625 * 100 = 89.0625

1 - 89.0625 = 10.9375%

-( ( 7 - u )( u - 2 ) ) is the factorized form of the polynomial -7u² + 12u + 4, using the AC method.

Given the polynomial in the question;

-7u² + 12u + 4

Factor out -1 out of the polynomial

-1( 7u² - 12u - 4 )

Compare to the form ax² + bx + c

To factor, compare to the form ax² + bx + c and rewrite the middle term as a sum of two terms whose product is;

a × c = 7 × -4 = -28

and whose sum is;

b = -12

Now, factor -12 out of -12x

-1( 7u² - 12(u) - 4 )

We know that -13 is the same as 2 plus -14

-1( 7u² - ( 2 - 14 )u - 4 )

Apply distributive property

-1( 7u² - 2u - 14u - 4 )

Group the terms

-1( u(7u - 2) - 2(7u - 2 ) )

-1( (7-u)(u-2) )

-( (7-u)(u-2) )

Therefore, the factorized form of the polynomial is -( ( 7 - u )( u - 2 ) ).

mutiply 14 by 6704

Step-by-step explanation:

The multiplication expression for the area covered is 3 x 8 and the number of grids will be 24.

Multiplication is the general procedure in mathematics in which we multiply two or more numbers by each other to find a new multiplied number.

Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.

As per the given decimal grid,

The number of colored raw = 8

The number of colored columns = 3

Total grids = 8 x 3 = 24

Hence "The multiplication expression for the area covered is 3 x 8 and the number of grids will be 24".

Answer:

C = 62.8

Step-by-step explanation:

C = 2πr

π = 3.14

diameter = 20 ft

r = 10 ft

Get r or the radius by taking half of the diameter which is 20 ft and get 10 ft.

Plug this information in the formula and multiply to get C or the circumference.

C = 2(3.14)(10)

C = 62.8

The square root of a number can also be negative number so x could also be -9

Square root of a number is the number such that if it is multiplied by itself we get the square. The opposite of squaring an integer is finding its square root. As we know multiplication of two negative numbers produce a positive number. this is the reason why square of both positive and negative numbers are both positive. therefore, square root of a number can also be positive or neegative both. That is why we can't take square root of negative numbers.

Step-by-step explanation:

the work is all in the pic go check it out I am so sorry if it's incorrect also have a nice day:)

The unknown angles are as follows:

The value of ST in the line segment is 22 units.

An angle bisector is a bisector that bisect an angles into two equal parts.

Therefore, EF is the angle bisector of ∠EFG.

The bisector divides the ∠EFG equally into ∠EFH and ∠HFG.

Hence,

∠EFH  = ∠HFG

m∠HFG = 80°

m∠EFH  = 80°

m∠EFG = 80 + 80

m∠EFG = 160°

12.

Let's find ST in the line segment.

PT = 40

QS = 12

PQ = QR = RS = x

QR + RS = QS

2x = 12

x = 12 / 2

x = 6

Therefore,

PQ = QR = RS = 6 units

PS = PQ + QR + RS

PS = 6 + 6 + 6

PS = 18 units

Hence,

ST = PT - PS

ST = 40 - 18

ST = 22 units

Answer: 195/4

Step-by-step explanation:

Answer:

y = 3

Step-by-step explanation:

20 = 4 (y + 8) - 8y

20 = 4y + 32 - 8y

20 - 32 = 4y - 8y

-12 = -4y

-4y = -12

-4y/-4 = -12/-4

y = 3

To check

20 = 4 (y + 8) - 8y

20 = 4 (3 + 8) - 8(3)

20 = 12 + 32 - 24

20 = 44 - 24

20 = 20

Correct~

Answer: y = 3

Step-by-step explanation:

1. Distribute the 4 to the terms in the parenthesis.

20 = 4y + 32 - 8y

2. Combine like terms (those containing y).

20 = -4y + 32

3. Isolate terms with y by subtracting 32 from both sides.

-12 = -4y

4. Divide both sides by -4.

3 = y

Answer:

y=(5/2)x-4

Slope =5/2

2) the next is to find the y-axis

the line land on the x=0 at -4

y-axis=-4

3) plug into slope intercept form

y=mx+b

m=slope

b=y-axis

y=(5/2)x+(-4)

y=(5/2)x-4

Answer:

[tex]y=\frac{5}{2}x-4[/tex]

Step-by-step explanation:

2. we find the gradient between the two points using this equation m=[tex]\frac{y2-y1}{x2-x1}[/tex]

3. we plug the value in the equation

4. m = 5/2

5. equation of a straight line is y = mx +c

-where c is the intercept of the graph and m is the gradient

-4=5/2(0)+c

c =-4

To determine  probability with replacement, It uses sampling with replacement. In other words, you want to determine the likelihood of an event in which you choose a ball, card, or other object from a set of options and then swap it out after each choice.

Example:

Consider a scenario in which you wished to sample two people from a population of seven.

Those people are:

John, Jack ,Qiu, Tina, Hatty, Jacques, Des

Their names could be placed in a hat. If you sample with replacement, you would pick one name, put it back in the hat, and then pick a different name. Your two-name sample has the following potential outcomes:

John, John

John, Jack

John, Qui

Jack, Qui

Jack Tina

…and so on.

The two products you sample with replacement are independent. In other words, the outcome of one has no bearing on the other. The odds of picking the first name are 1/7, and the odds of picking the second name are 1/7.

P(John, John) = (1/7) * (1/7) = .02.

P(John, Jack) = (1/7) * (1/7) = .02.

P(John, Qui) = (1/7) * (1/7) = .02.

P(Jack, Qui) = (1/7) * (1/7) = .02.

P(Jack Tina) = (1/7) * (1/7) = .02.
