Answer: $817.35
Step-by-step explanation:
150x4 = 600
600+217.35 = 817.35
The number with the same value will be 40 because 10 tens make 100 and 4 tens make 40 so it wili be 140
To find the side lengths, you have to factor 4x^2 + 28x + 49. This equation factored is (2x+7)(2x+7), so each side length is (2x+7) feet.
Answer: it cant even be factored
Step-by-step explanation:
15,56^2=x^2+x^2
242,1136=2x^2
x^2= 242,1136:2=121, 0568
x≈11,003
