Answer:
Step-by-step explanation:
(3x^2 + 2x) + (-x + 9) Remove the brackets
3x^2 + 2x - x + 9 Watch out for the sign in front of the x
3x^2 + x + 9 No more reduction can take place.
(-2x^2 + 5x - 7) + (3x + 7) Remove the brackets
-2x^2 + 5x - 7 + 3x + 7
-2x^2 + 5x + 3x - 7 + 7 Combine
-2x^2 + 8x The 7s cancel -- they are of opposite signs.
No more reduction can take place. The powers on the variables have to be equal before any cancelation can take place.
Answer:
B. 13
Step-by-step explanation:
Answer:
x = 2
z = 89
Step-by-step explanation:
13x + 65 = 91
subtract 65
13x = 26
divide by 13
x = 2
91 + z = 180
subtract 91
z = 89
hopefully this helps you
The answer is 34%
30+33%=39.9
So round up two 34%
I hope that is right but I think the answer is 34%
Answer:
answer is 7
Step-by-step explanation:
just go down the list plugging in the numbers
4(1)+8=4+8=12
4(7)+8=28+8=36 this is the answer
4(11)+8=44+8=52
4(36)+8=144+8=152
