<span>(-4s)(2s³)
We're multiplying two monomials. Multiplying the numerical values first, (-4)(2), would give us -8. To multiply the s values, (s)(s</span>³), we just have to add the exponents. Keep in mind that
. Adding the exponents of the variable s gives us
. Our answer is
.
Answer:
Step-by-step explanation:
Let the width be x
- Then the length is 3x + 2
- Perimeter = 66
<u>Perimeter formula</u>
<u>Substitute values</u>
- 66 = 2(3x + 2 + x)
- 33 = 4x + 2
- 4x = 31
- x = 31/4
- x = 7.75
<u>The length is:</u>
<u>Answer:</u>
