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

Simplify 2n - 7+3(4n-3)<br> A.14n-16<br> B. -14n+12<br> C.-14n-13<br> D.14n-10
Hoochie [10]
<span>Simplifying 2n + -7 + 3(4n + -3) = 0 Reorder the terms: 2n + -7 + 3(-3 + 4n) = 0 2n + -7 + (-3 * 3 + 4n * 3) = 0 2n + -7 + (-9 + 12n) = 0 Reorder the terms: -7 + -9 + 2n + 12n = 0 Combine like terms: -7 + -9 = -16 -16 + 2n + 12n = 0 Combine like terms: 2n + 12n = 14n -16 + 14n = 0 Solving -16 + 14n = 0 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '16' to each side of the equation. -16 + 16 + 14n = 0 + 16 Combine like terms: -16 + 16 = 0 0 + 14n = 0 + 16 14n = 0 + 16 Combine like terms: 0 + 16 = 16 14n = 16 Divide each side by '14'. n = 1.142857143 Simplifying n = 1.142857143</span>
