Answer:

n = -2

Step-by-step explanation:

add 7 to both sides

1+8n = -15

subtract 1 from both sides

8n = -16

divide both sides by 8

n = -2

Answer:

n=-2

Step-by-step explanation:

1+8n-7=-22 Original Equation

(1-7)+8n=-22 Combine like terms

-6+8n=-22 After combining like terms

-6+8n=-22 Add +6 to cancel it out on the left side, and to add it on the other.

+6 +6

8n=-16 Divide both sides by 8

n=-2

The variables X, Y, and Z represent polynomials where X = a, Y = 3a – 5, and Z = a2 + 2. What is X2Y – Z in simplest form?

creativ13 [48]

Answer:

$3a^3-6a^2-2$

Step-by-step explanation:

Given

$x=a$
$y=3a-5$
$z=a^2+2$

We need to find the expression for $x^2y-z$ in simplest form. Hence we plug in the substitutions into the expression and simplify:

$x^2y-z\\=(a)^{2}(3a-5)-(a^2+2)\\=3a^3-5a^2-a^2-2\\=3a^3-6a^2-2$

2nd answer choice is right.

Based on the calculations on the bisector of ST, the value of ST are equal to 38 and 30 respectively.

<h3>How to find the bisector of ST?</h3>

In order to determine the bisector of a line segment with two (2) endpoints, we would add each point together and divide by two (2).

For exercise 1, we have:

ST = SM + MT

ST = 19 + 19

ST = 38.

For exercise 2, we have:

First of all, we would determine the value of x as follows;

3x - 6 = x + 8

3x - x = 8 + 6

2x = 14

x = 14/2

x = 7.

ST = SM + MT

ST = 3x - 6 + x + 8

ST = 3(7) - 6 + 7 + 8

ST = 30.
