For this question, all you have to do is combine like terms. I am assuming that the 3x2 and 5x2 are exponents, so they are one pair and then -4x and 8x are the other. The rule is the higher exponent goes first, so here is what it looks like:
3x2 - 4x - 5x2 +8x
First combine the numbers with exponents, 3x2-5x2, you always bring over the positive or negative, which ever it may be, in this case, since it is -5x2, you bring that over.
3x2-5x2=-2x2
Now to do the number with matching letters, -4x+8x= 4x
Now just bring the problem back together:
-2x2+4x
That is your simplified answer: -2x2+4x.
One way to solve:
960-12x=816
144=12x
12=x
Another way to solve
80-x=68
x=12
Answer:
D
Step-by-step explanation:
We can plug in the numbers (15, 23, 25, 38, 53) into the equation for x, and see if we get the values given for the number of hits (4, 12, 14, 27, 47)
Answer:
i think its
1/2 1/4 2 then 4
Step-by-step explanation:
its kinda easy
Answer:
one angle is 90° .
Angle x is45 because 180-90=90
90/2=45°
