Need help with math problem if do get 5 star

Area = 1/2 x b x h

= 1/2 x 8 x 4 = 16

D. 16 square units

16 square units

Step-by-step explanation:

The area of a triangle is

A = 1/2 bh where b is the base and h is the height

The base is x which is 8 and the height is 4

A = 1/2 (8)*4

A = 1/2 (32) = 16 units^2

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
