Step-by-step explanation:
You can set up a proportion.
Let x be the number of pencils needed.

Solve for x.
x = 9444.44 pencils (round it up to 9445 pencils if you need a whole number)
7*6*x^-8*x^3
42x^-8+3 (bases same powers add)
42x^-5
1/42x^5
<span>so the simplified </span>form<span> of 7x^-8*6x^3 is=1/42x^5</span>
Answer:
132 in
Step-by-step explanation:
rectangle- 12(8)=96
