The area of a triangle is 1,440 cm2. The base of the triangle is 5 times the height. What is the height of the triangle?

step-by-step explanation: it is d

if i put something wrong your not gonna like it so rather not say nothing.

i think its a.

hope this

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
