Answer:
A = 188
Step-by-step explanation:
+ replace x = -6 and y= 2 into 3 x squared minus 5 x y + 5 y squared = A
So A= 3x^2 - 5xy + 5y^2
A = 3 *(-6)^2 -5* (-6) *2 +5* 2^2
A = 3* 36 +60 + 5*4
A= 108 +60 +20
or A = 188
Have a good day

13987.17=p(1+0.032/2)^2*7
Solve for p
P=13,987.17÷((1+0.032÷2)^(14))
P=11,199.99
