1) 9 cm2 A shape is made of 10 right triangles of
equal size. Each right triangle has a
2) 50 cm2
base of 3 cm and a height of 6 cm.
3) 90 cm2
What is the total area, in square
4) 180 cm2
centimeters, of the shape?

b and c

step-by-step explanation:

x = 12

y = 1

for the points!

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
