D because you need to make the denominators have a common multiple.
Answer:
-16x + 14 or 2(7-8x)
Step-by-step explanation:
= 2(x + 7) – 18x
= 2x + 14 -18x
= -16x + 14
or
= 2(7-8x)
To start, first distribute 8 to (y+11) which would look something like this:
9y=8y+88
Now, subtract 8y from both sides in order to solve for and isolate the y value. This would result in your answer, y=88.
Answer:
Step-by-step explanation:
If you want to factor
, you could throw that into the quadratic formula with a = 1, b = 11 and c = 0, but the easier thing to do is to factor out what's common in those 2 terms. m is common, so when we factor it out:

That's the factored form.
By the Zero Product Property, either
m = 0 or m + 11 = 0.
So the 2 solutions to this are
m = 0 or m = -11
Not sure how far you need to go with this.
Answer:
3) 4x² -1
Step-by-step explanation:
A quadratic equation is a 2nd-degree polynomial equation.
1) an exponential equation (the variable is in the exponent)
2) a cubic equation (degree = 3)
3) a quadratic equation
4) a linear equation (degree = 1)
