Step-by-step explanation:
4h+6h2+1−(5h2−8h4+6)
=4h+6h2+1+−1(5h2−8h4+6)
=4h+6h2+1+−1(5h2)+−1(−8h4)+(−1)(6)
=4h+6h2+1+−5h2+8h4+−6
=4h+6h2+1+−5h2+8h4+−6
=(8h4)+(6h2+−5h2)+(4h)+(1+−6)
=8h4+h2+4h+−5 <- Answer

<h3><u>The length is equal to 8.</u></h3><h3><u>The width is equal to 4.</u></h3>
2l + 2w = 24
l = 3w - 4
Because we have a value for l, we can plug it into the first equation to solve for the exact value of w.
2(3w - 4) + 2w = 24
Distributive property.
6w - 8 + 2w = 24
Combine like terms.
8w - 8 = 24
Add 8 to both sides.
8w = 32
Divide both sides by 8.
w = 4
Now that we have a value for w, we can plug it into the second equation to solve for the exact value of l.
l = 3(4) - 4
l = 12 - 4
l = 8
Your answer should be 17 inches.
2.5 + 2.5 = 5 7 + 3 = 10 + 5 + 2 = 17.
I hope this helps answer your question. Have a great day

Answer:
3 and 18
Step-by-step explanation:
let x be the first number
let 6x be the second number
x + 6x = 21
7x=21
x=21/7
x=3
second number =6x
second number 6x3= 21
