Answer:
no
Step-by-step explanation:
Area of trapezoid = 1/2 (sum of parallel sides) × (perpendicular distance between them)
Area = 1/2 × (3 + 7) × 2 = 10 ft²
Answer:
x=-3
Step-by-step explanation:
3(x-6)+6=5x-6 - Problem
The Distributive property says a(b+c)=ab+ac. Using this knowledge, lets solve.
1) Distribute 3 to x and -6:
3x-18+6=5x-6
2) Combine alike terms: (-18 and 6)
3x-12=5x-6
3) Subtract 3x from both sides:
-12=2x-6
4) Add 6 to both sides:
2x=-6
5) Divide both sides by 2:
x=-3
The practical rule would be, times that number, by the result of the first time you multiplied the first number. But, it would all depend by how much your're raising the number by.

For example:</u>

We do,

But, once again, this was an example. This would show and illustrate the rule of "raising a power".<span />
