Each side length of the parallelogram at the right is multiplied by four. Describe the change in the perimeter.

1 answer:

6 0

Side length1 = x
side length2 = y

2x + 2y = perimeter

2(4x) + 2(4)y = new perimeter
8x + 8y = new perimeter

new perimeter = 4 times the old perimeter

Answer:

Step-by-step explanation:

$\bullet\; \tt{(3y)^2} = 3^2y^2 = 9y^2}$

$\bullet\; \tt y^{-1} = \dfrac{1}{y}\\\\\bullet\;(3y)^2 \times y^{-1} = 9y^2 \times \dfrac{1}{y } = \dfrac{9y^2}{y}\\\\\\bullet \tt \dfrac{y^2}{y} = y\\\\\tt \bullet \dfrac{9y^2}{y} = 9y$

Answer:x=−24/11

Step-by-step explanation:

Simplifies to:

x−86x=79

Let's solve your equation step-by-step.

x−86x=79

Step 1: Cross-multiply.

x−86x=79

(x−8)*(9)=7*6x

9x−72=42x

Step 2: Subtract 42x from both sides.

9x−72−42x=42x−42x

−33x−72=0

Step 3: Add 72 to both sides.

−33x−72+72=0+72

−33x=72

Step 4: Divide both sides by -33.

−33x−33=72−33

x=−2411
