I’m going to say multiply both sides by a which gives you:
a^2-ab-a=2
If not give me a call
Let the number of blue marbles be x
number of yellow marbles = x/3
number of green = x- 90
ATQ
x + x/3 + x - 90 = 694
2x + x/3 = 784
(6x + x)/3 = 784
7x/3 = 784
x = 784 x 3/7
x = 112 x 3
x = 336
number of blue marbles = 336
Answer: (6x-3y)3 or maybe not possible to do
Step-by-step explanation
multiply 3x2 and get 6. Multiply 3x3 and get 9.
We have been given an expression 
. We have been given steps how Chris tried to solve the given expression. We are asked to choose the correct option about Chris's work.
Let us simplify our given expression.
Using exponent property, 
, we cab rewrite our given expression as:
Now we will use exponent property 
to further simplify our expression.
Therefore, Chris made mistake in step 2.
