A rectangle has a perimeter of 30. It is dilated by a scale factor of 2.
LuckyWell [14K]

Answer:

It is 60.

Step-by-step explanation:

When shapes are dilated (when they get bigger or smaller), perimeter changes linearly—in direct proportion with length. This means if the scale factor is 2, then you multiply it by 2. 2 multiplied by 30 equals 60.

4x + 11 = 6x - 15 find x
Elina [12.6K]
4x + 15 = 6x + -11

Reorder the terms:
15 + 4x = 6x + -11

Reorder the terms:
15 + 4x = -11 + 6x

Solving
15 + 4x = -11 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.
15 + 4x + -6x = -11 + 6x + -6x

Combine like terms: 4x + -6x = -2x
15 + -2x = -11 + 6x + -6x

Combine like terms: 6x + -6x = 0
15 + -2x = -11 + 0
15 + -2x = -11

Add '-15' to each side of the equation.
15 + -15 + -2x = -11 + -15

Combine like terms: 15 + -15 = 0
0 + -2x = -11 + -15
-2x = -11 + -15

Combine like terms: -11 + -15 = -26
-2x = -26

Divide each side by '-2'.
x = 13

Simplifying
x = 13
