What is the answer to 4+x+7 + x = 33 A. 11 B. -11 C. 12 D. 22

1 answer:

8 0

First move the numbers to the other side
x+x = 33-4-7
2x = 22
Next divided both sides by 2 to get x on its own
X=11
Therefore the answer is A

12.
Add like terms from both trinomials:

$4x^{2} + -2x^{2} = 2x^{2}$
$2x + -5x = -3x$
$-1 + 3 = 2$

Combine these terms to get a new trinomial as your answer:

$2x^{2} - 3x + 2$

13.
Subtract like terms from both trinomials (note that subtracting a negative is the same as adding it as a positive):

$3x^{2} - 5x^{2} = -2x^{2}$
$-8x - -11x = -8x + 11x = 3x$
$-1 - -1 = -1 + 1 = 0$

0 can be left out of the answer.

Combine these terms to get a binomial as your answer:

$-2x^{2} + 3x$

AURORKA [14]

Rewrite it as 5x^2 -20x-3x+12
then (5x^2 -20x)(-3x+12)
then use gcf and u will get the answer in a binomial form
