Jamal has 2.5 feet of yarn
Step-by-step explanation:
Answer:
(D) 
Step-by-step Explanation:
Assuming that the equation 
= p, we can convert the equation into this.
We can convert 
into 9p because × 9 =
Now we simplify this equation.
We can subtract 9p from both sides of the equation.
Re-ordering the equation gets us:
So, (D) is equivalent to the original expression of 
Answer:
10 = b
Step-by-step explanation:
Begin by expanding (x + 5)^2
(x + 5)(x + 5)
First: x*x = x^2
Outside: x * 5 (the last term which is a 5)
Inside: 5+ x
Last: 5*5 = 25
x^2 + 5x + 5x + 25
x^3 + 10x + 25
It would have to be 81 over 1 for it to equal 81 but then again with a / for the fraction bar it can be hard to tell which way its written
