Answer:
The answer is number 2 because a positive number is always bigger than a negitive number
(-2)^4=16
(-2)^-1=-1/2
-1/2x16=-8
Answer: -8
Mother correct answer is -3,5
For this case, what you must do is take out the area of two triangles and add it to the area of a rectangle to find the total area.
We have then:
Triangle area:
A = (1/2) * ((13-9) / (2)) * (10) = 10 in ^ 2
Rectangle area:
A = (9) * (10) = 90 in ^ 2
Total area:
At = 2 * (10) + 90 = 110 in ^ 2
answer:
110 in²
