Answer:
12
Step-by-step explanation:
The area of a triangle is
A = 1/2 b *h
The base is 6 units (from -2 to 4)

A = 1/2 6*4
= 1/2 (24)
= 12 units^2
Don’t say you’re dumb ! we always need help sometimes.
(5x)^2 = ____x^2
distribute the exponent ‘2’ to both terms inside the parentheses.
so it will be (5)^2(x^2)
simplify. 5^2=25, (x^2)=x^2
so the answer is 25x^2
