Answer:
A=10x^2+14x
Step-by-step explanation:
A=wL
w=2x
L=5x+7
A=2x(5x+7)
A=10x^2+14x
- 374.4 is the answer
Explanation
3.6 * 106 = 381.6
7.2 * 105 = 756
Subtract 756 from 381.6
= - 374.4
Hope this helps :)
Have a great day !
What does x and y represent?
I'm assuming A=the hypotenuse
Set an equation using the pythagorean theorem:
100^2+249^2=a^2
10000+62001=a^2
72001=a^2
a=±268.3
Since distance cannot be negative, the answer would be:
A=about 268.3ft
