Answer:
7y^2 - y^2z - 10yz-5
C. 7 y squared minus y squared z minus 10 y z minus 5
Step-by-step explanation:
A. y squared minus y squared z minus 10 y z minus 5
B. y squared minus y squared z minus 5 y z minus 5
C. 7 y squared minus y squared z minus 10 y z minus 5
D. 7 y squared minus y squared z minus 2 y z minus 5
Given:
3y^2 - 6yz - 7 + 4y^2 - 4yz + 2 - y^2z
Collect like terms in the expression
3y^2 + 4y^2 - 6yz - 4yz - y^2z - 7 + 2
Simplify
7y^2 - 10yz - y^2z - 5
Rewritten as
7y^2 - y^2z - 10yz-5
Option C. 7 y squared minus y squared z minus 10 y z minus 5
Is the answer

Answer:
One length = 10
Two length = 20
One width = 2
Two width = 4
Step-by-step explanation:
The perimeter is 24
A rectangle has 4 sides
2 are length
other 2 is width
First, the length is 8 inches longer
there are 2 length so 8 + 8 = 16
That leave 8 inches left
divide 8 by 4 = 2
Add one length together
8 + 2 = 10
2 is the width
How to check you answer:
10 + 10 + 2 + 2 =24
