First expand the brackets by multiplying each thing inside the brackets by 2:
4x−10=6x+4. then minus the 4x so there are only x 's on one side:
−10=2x+4. then minus the 4 so there are only numbers on one side and x 's on the other:
−14=2x. then divide by 2 to get the value of x
What is the question to answer?
Answer:
-36
Step-by-step explanation:
1. Plug -3 into the equation given: -3(15-(-3)+2(-3)^2
2. Use Pemdas and first distribute the negative to negative three then distribute -3 to the rest of the parenthesis (final answer): -45-9 +2(-3)^2
3. Then put -3 to the power of 2 (which is 9) then multiply it by 2 (final answer): -45-9+18
4. Combine all like terms and you get the answer -36!
Answer:
C
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
- 2x(- 4x - 3) - 9y²(- 4x - 3) ← distribute both parenthesis
= 8x² + 6x + 36xy² + 27y² → C
Answer is 40
15/3 = 5
8 x 5 = 40
