Find the measurement

$6z + 7 = 8z - 9$

$8z - 9 = 6z + 7$

Add sides 9

$8z - 9 + 9 = 6z + 7 + 9$

$8z = 6z + 16$

Subtract sides 6z

$- 6z + 8z = - 6z + 6z + 16$

$2z = 16$

Divide sides by 2

$\frac{2z}{2} = \frac{16}{2} \\$

$z = 8$

Thus ;

$NP = 8z - 9$

$NP = 8(8) - 9$

$NP = 64 - 9$

$NP = 64 - 4 - 5$

$NP = 60 - 5$

$NP = 55$

Done...

Simply the attached question

Finger [1]

Answer:

=x⁴−x³−14x²

Step-by-step explanation:

<h3>Let's simplify step-by-step.</h3>

x²(3x²+5x−4)−2x²(x²+3x+5)

<h3>Distribute:</h3>

=(x²)(3x²)+(x²)(5x)+(x²)(−4)+−2x⁴+−6x³+−10x²

=3x⁴+5x³+−4x²+−2x⁴+−6x³+−10x²

<h3>Combine Like Terms:</h3>

=3x⁴+5x³+−4x²+−2x⁴+−6x³+−10x²

=(3x⁴+−2x⁴)+(5x³+−6x³)+(−4x²+−10x²)

=x⁴+−x³+−14x²

<h3>ANS-</h3>

=x⁴−x³−14x²
