X × x = x^2
x × -3 = -3x
3 × x = 3x
3 × -3 = -9
x^2 + 3x - 3x - 9
So I would agree with C because the -3x and the 3x cancel each other out. I hope this helps!
14x - (2x - y) - y
14x + (-1(2x - y)) - y
14x + (-1(2x) - 1(-y)) - y
14x + (-2x + y) - y
14x + 1(-2x + y) - y
14x + 1(-2x) + 1(y) - y
14x - 2x + y - y
14x - 2x
12x
Answer:
x = 704/39 ( <----Fraction)
Step-by-step explanation:
28 squared minus 39x minus 80 equals 0
784-39x-80=0 evaluate the power
704-39x=0 Subtract the numbers
-39x=-704 move the constant to the right hand side and change it's sign
Divide on both side to get x = 704/39
Answer:
Step-by-step explanation:
(-4 - 4)/(6 + 2)= -8/8= -1
y - 4 = -1(x + 2)
y - 4 = -x - 2
y = -x + 2
