Answer:
x² + x - 12 = 0
Step-by-step explanation:
If x = -4 and x = 3 are solutions to a quadratic equation, then
(x + 4)(x - 3) = 0
Expand the brackets: x² - 3x + 4x - 12 = 0
Combine like terms: x² + x - 12 = 0
Let x represent the width of the garden(s). Then the length of the second garden is (3x+3). The area is the product of length and width,
90 = x(3x+3)
30 = x(x+1)
At this point, you can recognize that 5 and 6 are factors of 30 that will satisfy this equation, or you can solve the quadratic
x² +x -30 = 0
(x +6)(x -5) = 0
x = 5 . . . . . . . the negative solution does not apply
The width of the garden is 5 m.
Hello :
<span>F(x) = 2x + 6, g(x) = 4x²
(f + g)(x)= f(x) +g(x) = 4x²+2x+6</span>

sooo UwU which becomes O////O then becomes T.T
Answer:
-6
Step-by-step explanation:
Ok so if x=2
you have to do -3*2
and thats -6
hope this helped
good luck
