Its A. x=4
procedure: 3*equation1 - 2*equation2 ⇒ x=4
23.536 54.653 it is decimal form
I’m not 100% bc/ I learned this last semester, but I think it’s B. So sorry if I’m wrong. I think this bc/ 0.04 is the interest rate as a percent, 4 is the time, 200 is the amount of money, and the one shows that it is exponential growth.
The perimeter of the rectangle is equal to the doubled sum of the sides, and the area is equal to the product of the sides. So we have the following equation
3 x 2x = 2(3 + 2x)
6x = 6 + 4x
2x = 6
x = 3
H=(√3)*a/2 = 41.2
So, a=2*41.2/√3=47.6
