Below in bold.

Step-by-step explanation:

4(5x + 6) = 12

20x + 24 = 12

20x = -12

x = -12/20 = -3/5

-3(2x - 4) = 18

-6x + 12 = 18

-6x = 6

x = -1.

26 = 2(3x - 2)

26 = 6x -4

30 = 6x

x = 30/6 = 5.

The greatest and the only common factor in the given expression 3x²y³-48y²+18x³y⁵ is 3.

So, 3x²y³-48y²+18x³y⁵:

So, we can also write the expression as:

Therefore, the greatest and the only common factor in the given expression is 3.

The probability that a gorilla will live longer than 26 years is between 15.8 and 24.2 years.

Likelihood is the part of science concerning mathematical portrayals of how likely an occasion is to happen, or how likely it is that a recommendation is valid.

P (A) is the probability of an event “A”

n (A) is the number of favorable outcomes

n (S) is the total number of events in the sample space

The likelihood of an occasion is a number somewhere in the range of 0 and 1, where, generally talking, 0 shows difficulty of the occasion and 1 demonstrates conviction. The higher the likelihood of an occasion, the almost certain it is that the occasion will happen. A straightforward model is the throwing of a fair coin. Since the coin is fair, the two results are both similarly likely; the likelihood of "heads" approaches the likelihood of "tails"; and since no different results are conceivable, the likelihood of by the same token "heads" or "tails" is 1/2.

Answer:

C

Step-by-step explanation:

Taking a square root of a number that doesn't have a square root like [tex]\sqrt{17}[/tex] will result in an infinite number of random digits which is an irrational number. Hence, C is the answer.

D isn't the answer because even though [tex]\sqrt{5}[/tex] is irrational, you're adding [tex]\sqrt{5}[/tex] and then subtracting [tex]\sqrt{5}[/tex] from the total sum. Hence the total sum would be 5+14.

5+[tex]\sqrt{5}[/tex]+14-[tex]\sqrt{5}[/tex] =5+14+[tex]\sqrt{5}[/tex]-[tex]\sqrt{5}[/tex]= 5+14 ==> 19 is a rational number

The equivalent of the given expression ( (4 1/2)x - 3 ) + ( -2 + (1 3/4)x ) is (6 1/4)x - 5.

Given the expression in the question;

( (4 1/2)x - 3 ) + ( -2 + (1 3/4)x )

First, convert the mixed fractions into an improper fractions.

( (4 1/2)x - 3 ) + ( -2 + (1 3/4)x )

( (4×2 + 1/2)x - 3 ) + ( -2 + (1×4 + 3/4)x )

( (8 + 1/2)x - 3 ) + ( -2 + (4 + 3/4)x )

( (9/2)x - 3 ) + ( -2 + (7/4)x )

Now, remove the parenthesis and collect like terms

(9/2)x - 3 + -2 + (7/4)x

(9/2)x + (7/4)x - 3 - 2

9x/2 + 7x/4 - 5

Now, add the two fractions containing x

(9x × 4)+(7x × 2)/8 - 5

( 36x + 14x )/8 - 5

50x/8 - 5

(50/8)x - 5

(25/4)x - 5

Convert 25/4 into an improper fraction

(6 1/4)x - 5

Therefore, the equivalent of the given expression ( (4 1/2)x - 3 ) + ( -2 + (1 3/4)x ) is (6 1/4)x - 5.

A triangle with two angles measuring 45⁰ and 92⁰ is an obtuse scalene triangle. The answer is A.

A triangle is a two-dimensional shape that has three sides and three angles. The sum of its interior angles is 180⁰.

If two angles of a triangle have measures 45⁰ and 92⁰, solving for the third angle

180⁰ = 45⁰ + 92⁰ + third angle

third angle = 43⁰

If a triangle has an angle greater than 90⁰, then it is an obtuse triangle.

If a triangle has angles less than 90⁰, then it is an acute triangle.

If a triangle has an angle equal to 90⁰, then it is a right triangle.

An isosceles triangle is a triangle with two congruent sides and congruent base angles (2 angles are equal).

An equilateral triangle is a triangle with all three sides equal and all three angles are of equal measures.

A scalene triangle is a triangle with no sides are equal and no angle are equal also.

Since our triangle has 3 unique angles: 43⁰, 45⁰, and 92⁰, with one angle greater than 90⁰, then it is an obtuse scalene triangle.

Answer:

F ' (-12, 8)

U ' (4, 4)

N ' (-4, -16)

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

Explanation:

I'm assuming the center of dilation is the origin.

Multiply each coordinate by the scale factor 2.

For point F, the x coordinate goes from -6 to  2*(-6) = -12. The y coordinate goes from 4 to 2*4 = 8

So F(-6,4) moves to F ' (-12, 8)

Use this idea for the other points.

If the center of dilation wasn't the origin, then we can't use this shortcut (not until translating the center to the origin).

The perimeter of the triangle ABC is approximately equal to 35.633 units.

In this problem we find the locations of the three vertices of the triangle and from which we have to calculate the length of each of the three sides. The perimeter is the sum of the three lengths. First, determine the vectors of each side:

AB = (2, - 9) - (- 3, 2)

AB = (5, - 11)

BC = (0, - 10) - (2, - 9)

BC = (- 2, - 1)

AC = (0, - 10) - (- 3, 2)

AC = (3, - 12)

Second, calculate the magnitudes of the three sides:

AB = √[5² + (- 11)²]
AB = √146

BC = √[(- 2)² + (- 11)²]

BC = 5√5

AC = √[3² + (- 12)²]

AC = 3√17

Third, add the three lengths to find the perimeter:

p = √146 + 5√5 + 3√17

p ≈ 35.633

The statement reports a typing mistake that it would take a triangle for an angle, which is absurd since angles only have one vertex. Correct statement is shown below:

Find the perimeter of Δ ABC to the nearest hundred, given the coordinates of its vertices A(x, y) = (- 3, 2), B(x, y) = (2, - 9) and C(x, y) = (0, - 10).

By using area formula, we get base is [tex]20 m[/tex]

What do you mean by area?

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. For instance, On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies.

Given that:

Area of a rhombus is [tex]400 m^{2}[/tex]

Height  of a rhombus is [tex]20 m[/tex]

We know that,

Area of rhombus = base × height

Substituting area and height in above formula

[tex]400[/tex] = base × [tex]20[/tex]

∴ Base = [tex]\frac{400}{20}[/tex]
