Answer:
y = -24 + -2x + 2x2
Step-by-step explanation:
Simplifying:
y = 2(x + 3)(x + -4)
reorder the terms:
y = 2(3 + x)(x + -4)
multiply (3 + x) * (-4 + x)
y = 2(3(-4 + x) + x(-4 + x))
y = 2((-4 * 3 + x * 3) + x(-4 + x))
y = 2((-12 + 3x) + x(-4 + x))
y = 2(-12 + 3x + (-4 * x + x * x))
y = 2(-12 + 3x + (-4x + x2))
Combine like terms 3x + -4x = -1x
y = 2(-12 + -1x + x2)
y = (-12 * 2 + -1x * 2 + x2 * 2)
y = (-24 + -2x + 2x2)
Solving:
y = -24 + -2x + 2x2
solving for variable 'y'
Move all terms containing y to the left, all other terms to the right.
Simplifying:
y = -24 + -2x + 2x2

Answer:
x = 16
Explanations:
The given rquation is:
Step 1: Cross multiply the equations. That is 28 multiplies 4 and 7 multiplies x:
112 = 7x
Step 2: Divide both sides by 7
16 = x x = 16
Yo sup??
Given inequality
-3 < n <1
since -3 and 1 isn't included therefore we have to see the option having open circle....he one which isn't filled
therefore the answer is option D
Hope this helps.
