Because we have to evaluate was in the parenthesis and then solve it, then we need to remember to multiply first before going to the addition
In this question, you're solving for n.
Solve for n:
5(1 - 5n) = -4n+5
<em>Use the distributive property</em>
5 - 25n = -4n + 5
<em>Add 25n to both sides</em>
5 = 21n + 5
<em>Subtract 5 from both sides</em>
0 = 21n
<em>Divide both sides by 21</em>
n = 0
Answer:
n = 0
So, this is kinda similar to the other I helped you with:
<span>So r is the radius of the disk. The area is known and equal to 100Pi; so
100Pi = Pi r2
Now for r: r = 10
Circumference = 2 PI r = 20 Pi
I hope this helped!</span>
