Answer:
12a) 4L - 6 = Perimeter
13) 4(6x + 9)
Step-by-step explanation:
for #12: two sides of the rectangle are referred to as L
The other two sides can be referred to as L-3 (these sides are the width, which are 3 less than the length)
Perimeter = sum of all sides; so, 2L + 2(L-3)
P = 2L + 2L - 6
= 4L - 6
Given expression 3² × 3⁻⁵
We will apply the power rule

3² × 3⁻⁵ = 3²⁺⁽⁻⁵⁾ = 3²⁻⁵ = 3⁻³
We will then apply the power rule

3⁻³ =
