A shape is made up of 8 right triangles of equal size. each right triangle has a base of 4cinches and a height of 15 inches. what is the area in square inches of the shape​

area = 240 in²

Step-by-step explanation:

each triangle area = 1/2(4)(15) =30 in²

30 x 8 = 240 in²

240 inches²

Step-by-step explanation:

Area of Triangle = height x base  = 15 x 4 = 60 = 30

                                       2                     2        2

                           = 30 x 8 = 240 inches ²

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
