The formula for area of a triangle is: 1/2 x base x height.
You are given the height of 4 and the area of 4.
Replace those in the formula and solve for x ( base)
4 = 1/2 x base x 4
Divide both sides by 4:
1 = 1/2 x base
Multiply both sides by 2:
2 = base
x = 2
First set up an equation as your approach. I will use the equation x+4x=24 because that way you are saying that something pluse itself times 4 equals 24 which is what you want.
simplify the equation
5x=24
x=24/5
So you know onw piece will be 24/5 of a foot and the ither qould be that times 4 so 96/24 of a foot. In decimals it would be 4.8 and 19.2
Answer:
see explanation
Step-by-step explanation:
Given
P(x) = x³ + 7x² + 4x, then
P(a) = a³ + 7a² + 4a ← substitute x = a into polynomial
To evaluate P(- 2) substitute a = - 2 into P(a)
P(- 2) = (- 2)³ + 7(- 2)² + 4(- 2) = - 8 + 28 - 8 = 12
Since P(- 2) ≠ 0 then (x + 2) is not a factor of P(x)
