The value of X is 35 because the angle 35 measures the same as the angle X, hence their values are the same
Answer:
-3=x
Step-by-step explanation:
First you must add the X's on each side which gives you: 1x-2= -x - 4 - 4
Next you must add the first number 4 to the - 2 on the other side.
Then you do the exact same thing with the other number 4.
After that you get 1x+6=-x, then you subtract the 1 x with the -x to get 6= -2x.
Finally divide both sides by 2 and your final answer is -3 = x
15 is 9 more that j
Let is be the = sign.
Let more than be the + sign.
15 = 9 + j
Factor the following:
x^2 - 5 x - 24
Hint: | Factor x^2 - 5 x - 24 by finding two numbers whose product is -24 and whose sum is -5.
The factors of -24 that sum to -5 are 3 and -8. So, x^2 - 5 x - 24 = (x + 3) (x - 8):
Answer: (x + 3) (x - 8)

Factor the following:
49 x^2 - 64
Hint: | Express 49 x^2 - 64 as a difference of squares.
49 x^2 - 64 = (7 x)^2 - 8^2:
(7 x)^2 - 8^2
Hint: | Factor the difference of two squares.
Factor the difference of two squares. (7 x)^2 - 8^2 = (7 x - 8) (7 x + 8):
Answer: (7 x - 8) (7 x + 8)

Factor the following:
x^2 - x - 110
Hint: | Factor x^2 - x - 110 by finding two numbers whose product is -110 and whose sum is -1.
The factors of -110 that sum to -1 are 10 and -11. So, x^2 - x - 110 = (x + 10) (x - 11):
Answer: (x + 10) (x - 11)___________________________________________________________
