QA.
<span>Assuming the dimensions have to be in exact feet then you could have </span>
<span>9ft *9ft = 81square feet </span>
<span>10 ft * 10 ft = 100 square feet </span>
<span>11 ft * 11 ft = 121 square feet. </span>
<span>QB. </span>
<span>If each tile is 1 ft * 1 ft ie 1 square foot </span>
<span>Then </span>
<span>9' * 9' would mean 125 - 81 = 44 tiles would not be used </span>
<span>10' * 10' = 125 - 100 = 25 tiles not used </span>
<span>11' * 11' = 125 - 121 = 4 tiles not used </span>
Answer:
Yes, they are equivalent.
Step-by-step explanation:
They are equivalent, to see this, simplify the expression.
Distribute into the parenthesis.
5(y)- 5(2)
Then simplify into...
5y-10
This is equivalent to 5y-10
<h2>5y-10 =
5(y-2)</h2>
