If f(x)=-3x+8,find (f)5 a.-7 b.5 c.-5 d.7

A.-7

Step-by-step explanation:

f(x)=-3x+8,

f(5) means let x=5

f(5) = -3(5) +8

f(5) = -15+8

f(5) = -7

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
