Is there a photo? I know the last option is true but I feel like there should be a photo with this
Answer:
A = (2x² + 4x + 1) (8 − x)
A = -2x³ + 12x² + 31x + 8
Step-by-step explanation:
W = 2x² + 4x + 1
L = 8 − x
Area is width times length.
A = (2x² + 4x + 1) (8 − x)
If you wish, you can simplify with distribution.
A = 8 (2x² + 4x + 1) − x (2x² + 4x + 1)
A = 16x² + 32x + 8 − 2x³ − 4x² − x
A = -2x³ + 12x² + 31x + 8
The answer will be C. In the picture you will see 2144 which is the answer.
Answer: She is correct because each ratio is equivalent to 5:1, except for the last one, which is 1:5
5/1 = 5:1
10/2 = 5:1
25/5 = 5:1
10/50 = 1:5
