Hi there!
The formula for the area of a kite is A = 1/2(d1 x d2). Using this formula, all we need to do to find the area is to plug in each diagonal length, then solve the equation.
WORK:
A = 1/2(15 x 16)
A = 1/2(240)
A = 120cm^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
(2x-3)(5x+9)
2x*5x-3*9
10x-27
Total = amount Amy has(A) + amount Ruben has(R) + amount Sam has(S)
S = 3 * R
R = A + 9
S = 3 * (A+9)
S = 3A + 27
71 = A + (A + 9) + (3A + 27)
71 = 5A + 36
5A = 35
A = $7
R = A + 9
R = 7 + 9
R = $16
S = 3 * R
S = 3 * 16
S = $48
