1) 7^3 x 7^4 = 7^(3+4) = 7^7
2) (-6)^12 x (-6)^5 x (-6)^2 = (-6)^(12+5+2) = (-6)^19
3) 2^2 x 2^7 x 2^ 0 = 2^(2+7+0) = 2^9
Answer:
x = 4
Step-by-step explanation:
4(5x - 2) = 72
Do the distributive property
20x - 8 = 72
Then add 8 to both sides to get 20x alone
20x - 8 = 72
+ 8 + 8
20x = 80
Then divide both sides by 20 to get x
x = 4
Answer:
C) 8x-4
Step-by-step explanation:
Ultimately you want the two problems to be equal. It is not 6x because if you distribute 3 in this case, you will get 18x so it is 8x, it is also not -12 because it will be -36 as a result, so your answer is 8x-4.
3x and 2x are alike terms, as they have the same variable
