Answer:
x=-3,x1/2
Step-by-step explanation:
f(x)=(2x-1)(x+3)
TI find x intercept/zero substitute
f(x)=0
0=(2x-1)x(x+3)
swap the sides of the equation
(2x-1)x(x+3)=0
when the product of factors equals 0,at least one factor is zero
2x-1=0
x+3=0
solve the equation for x
x=1/2
x+3=0
solve the equation of x
x=-3
The equation has two solution
x=-3
x=1/2

Answer:
90ft
Step-by-step explanation:
I draw it out and add a dotted line to make a triangle and rectangle then you find the area of them individually and add the two together.
Rectangle:
6*3=18
Triangle:
Add the 6+6 together to get the height of the triangle and subtract the 3 from the 15 to get the base
(12*12)
144/
72
Total area:
18+72
90ft
