15.
4(x-2) = 2(x-4)+2x
i used the distributive property on the parantheses to then get...
4x-8 = 2x-8+2x
I combined the like terms to then get...
4x-8 = 4x-8
+8 +8
4x = 4x
which simplifies to....
x=x
so the answer to question 15 is x=x
17.
-4(p+1) = -2(8-2p)
I used the distributive property on the parantheses....
-4p-4 = -16+4p
+4 +4
-4p = -12+4p
-4p -4p
-8p = -12
÷-8 ÷-8
p = 1.5
so the answer to question 17 is p = 1.5
hope this helps!!!!
X4 + 8 = -36
x4 = -44
x = -11
(-11)4 + 8 = -36
-44 + 8 = -36
-36 = -36
Answer:
r=41/2
Step-by-step explanation:
The radius of a circle is always half it's diameter. In this circle, the diameter is 41 centimeters, so the radius would be half of that- which is 41/2 or 20.5 cm.
Hope this helps!
Subtract 'x' from each side. Then 3 > 5 . No value for 'x' can make that statement true. The inequality has no solution.

You need to complete the square for both x and y.

The center is (2, -1).
The radius is 4.
