25 x 13 = 325
20x 8 = 160
325-160 = 165 square feet
answer is A
Answer:
y = -6x +13
Step-by-step explanation:
slope = rise over run
-12 rise for 2 run
slope = -6
y intercept = 13
We can first add all them up:

Since it's for a square, we have to divide by 4:

So, the expression for a square with the exact same perimeter is
3x + 1
The answer should be 2.5, because you are cutting the value that they gave you in half
Answer:
- 6, 9 and 27
Step-by-step explanation:
Substitute a = - 3 into the expressions and evaluate
(a)
2a = 2(- 3) = - 6
(b)
a² = (- 3)² = 9
(c)
3a² = 3(- 3)² = 3(9) = 27
