What step is it called when numbers go from negative to positive in an equation? For example -x = -5 going to x = 5.
Neporo4naja [7]

Answer:

  B. Multiplication or Division property of equality

Step-by-step explanation:

Both sides of the equation have been multiplied by -1. The multiplication property of equality tells you that multiplying both sides of the equation by the same number does not change the truth of the equation (and the variables retain their values).

The width of a rectangle is 13 units less than the length. If the area is 90 square units, then find the dimensions of the recta
Artemon [7]

If the area is 90 square units. Then the dimension of the rectangle will be 5 units and 18 units.

<h3>What is the area of the rectangle?</h3>

Let L be the length and W be the width of the rectangle.

Then the area of the rectangle will be

Area of the rectangle = L×W square units

The width of a rectangle is 13 units less than the length.

If the area is 90 square units.

W = L – 13

Then we have

                           90 = L(L – 13)

         L² – 13L – 90 = 0

L² – 18L + 5L – 90 = 0

L(L – 18) + 5(L – 18) = 0

         (L – 18)(L + 5) = 0

                             L = -5, 18

Then the width will be

W = 18 – 13

W = 5 units

Then the dimension of the rectangle will be 5 units and 18 units.

More about the area of the rectangle link is given below.

Angels I need MAJOR HELP
Vlada [557]
<2 and <3 are supplementary angles...therefore they must equal 180°

since <2 = 125
you can find the measure of <3 by subtracting the measure of <2 from 180°

180 - 125 = 55° < answer

hope this helps :)
