What is 3 times 3 power 2x times 3 power negative 2 minus 3 power 2x times 3 and why?
I read that as: (3) x (32x) x (3-2) - (32x) x (3) = 32x(3 x 3-2 - 3) = 32x (3-1 - 3) = 32x-1(1 - 32) = -8 x 32x-1 When multiplying the same base (number) to any power, keep the base and add the powers, eg: 32x x 3-1 = 32x + (-1) = 32x-1 3 x 3-2 = 31 x 3-2 = 31-2 = 3-1
4x-3 equals 2x plus 5?
4x - 3 = 2x + 54x - 2x = 5 + 32x = 8x = 8/2x = 4To check:4(4) - 3 = 132(4) + 5 = 13
Is 2x plus 7 equals 8 equivalent to 2x equals 1?
no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )
How do you solve 22 decreased by 2 times a number yields 8?
write and equation...22 - 2x = 822 - 22 - 2x = 8 - 220 - 2x = -14-2x = -14-2x/-2 = -14/-2x = 7
What is -7 plus 2x equals x plus 8?
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
What is 3 times 3 power 2x times 3 power negative 2 minus 3 power 2x times 3 and why?

What is 2x plus 8 squared?
2X + 8^2 = 2X+64, for whatever value X. If the question is (2x+8)², the answer is 4x²+32x+64 The formula is (a+b)² = a² + 2ab + b². a=2x, b=8, a²=4x², b²=64
What is the answer to 2x(8 7)-6divided by 2x(9-3)?
If you mean: 2 times (8+7)-6 then divided by 2 times (9-3) then the answer is 2

6x - 8 plus 2x - 5 equals 7 - 2x?
6x - 8 + 2x - 5 = 7 - 2x ?
What is -7 plus 2x equals x plus 8?
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
What times what equals- 8?
1x8 2x4 16x.5 32x.25
Is -8 a solution of -2x plus 7 -9?
No. If that's -2x + 7 = -9 -2x = -16 x = 8
Solve for X 6x-8 plus 2x-5 equals 7-2x?
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
