To know if p = -1 is a possible solution to <span>6(p – 4) = -30p, plug in -1 for p and see if the equation is true.
</span><span>6(p – 4) = -30p
</span><span>6(-1 – 4) = -30(-1)
</span>6(-1 – 4) = -30(-1)<span>
Solve the parentheses.
-1 - 4 = -5
</span>6(-5) = -30(-1)
Multiply.
6 • -5 = -30
-30 • -1 = 30
-30 = 30
This is not true, so p = -1 is NOT a possible solution for the <span>equation 6(p – 4) = -30p.

Well, to find the circumference of a circle, we can use the formula
C=2

r.
So just plug in 3.5 into the formula.
C=2

3.5.
Multiply and we get C=21.99. which is about 22
So our answer would be C. 22 feet.
Hope I helped!
