Area of a triangle: 1/2 base x height
81 ft^2 = 1/2 (18 feet) (height)
Solve for x
81 / (1/2 x 18) = 9 feet for height
Please brainliest me if this helped; trying to level up!
You can find it on Internet or if not on youtube
Answer:
Step-by-step explanation:
g(x) = 3f(-2x)
= 3*([-2x)² + (-2x) - 2)
= 3 (4x² - 2x - 2)
= 3 * (4x² - 4x +2x - 2) {Rewrite the middle term}
= 3 *[ 4x(x - 1) + 2(x - 1)]
= 3* [ (x -1) *(4x + 2)]
= 3(x - 1)(4x + 2)
x - 1 = 0 ; 4x + 2 = 0
x = 1 ; 4x = -2
x = 
Roots: x = 1 , (-1/2)
Okayyy i’ll try and join asap
