Who is correct? Explain your reasoning.
kap26 [50]
In order to get who was right we need to solve the expression:
2a^2b(-2ab^3)^-2
The above can be written as fraction to get:
(2a^2b)/(-2ab^3)^2
=(2a^2b)/(4a^2b^6)
=1/2(a^(2-2)b^(1-6))
=1/2a^0b^-5
=1/2b^(-5)
This implies that neither of the was right

Solve the equation: 5 - (t + 3) = - 1 + 2t - 3)<br> Show your work.<br> HELPPP MEEE PLEASSEEE !!!!
Finger [1]

Answer

t = 2

Step-by-step explanation

Simplify 5-(t+3).

-t+2=-1+2t-3

Subtract 3 from -1

-t+2=2t-4

Move all terms containing to the left side of the equation.

-3t+2=-4

Move all terms not containing t to the right side of the equation.

-3t=-6

Divide each term by -3 and simply.

t = 2

How do you solve this problem<br> (2x+8)2=64
asambeis [7]

Answer:

12

Step-by-step explanation:

If (2x+8)2 = 64, then I would solve it by making sure the numbers in the parentheses equal 32. This is because it would get multiplied by 2 after you find the answer and 32 x 2 is 64. So what times 2 is 24? 12. 12 x 2 is 24, plus 8 is 32, and multiply 32 by 2 and you get 64 :) I'm not the best at explaining btw ;-;
