Question:
Yuet solved the equation for a.
Her steps are shown below.
1. Subtract 2b:
2. Divide by 6:
Answer:
In step 1 she needed to add 2b to both sides of the equation.
Step-by-step explanation:
Given:
The above steps shows how Yuet solved an equation
Required:
True statement about Yuet's work
The implication of the statement is to state what Yuet should have done instead of what she did.
In step 1, she subtracted 2b from both sides of the equation; this is wrong.
Instead of subtracting, she ought to add 2b to both sides of the equation.
The correct steps and result is as follows:
1. Add 2b:
2. Divide by 6:
Hence, we can conclude that in step 1 she needed to add 2b to both sides of the equation.
Hi there!
We know that the formula for the area of a rectangle is height * width. Thus, we can multiply these two expressions together:
Now, we know through the distributive property that we can distribute the to everything in the parenthesis. Once this is done, we get:
Now, we know through the power rule that when two exponents are multiplied together with the same base, the exponent can be added together . This then would make our equation:
Giving us for our final answer:
Hope this helps!
