If we plug 2 in for x we get
4^2 or 4 x 4
And
2^4 or 2 x 2 x 2 x 2
4 x 4 is 16 and 2 x 2 x 2 x 2 is also 16
So when x=2 the difference between the 2 expressions is 0
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:
y=x+12/4
Step-by-step explanation:
y=4x-12
x=4y-12 (then make y the subject)
x+12=4y(divide both sides by 4)
y=x+12/4
if you mean the triangle one, it's 25cm
