Answer:

the answer is -p-30

Step-by-step explanation:

first you would distribute -5 to p and 6 = 4p-5p-30

second combine the like terms = -p-30

lastly it cannot be factored down any farther so the answer is just -p-30

$6z + 7 = 8z - 9$

$8z - 9 = 6z + 7$

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...

A trapezoid has a perimeter of 14 feet. What will the perimeter be if each side length is increased by a factor 7? 21 feet 98 fe

natka813 [3]

Answer:

Correct choice is B

Step-by-step explanation:

Let a, b, c and d be the trapezoid's sides lengths.

The perimeter of the trapezoid is the sum of all sides lengths, thus,

$a+b+c+d=14\ ft.$

If each side length is increased by a factor 7, then new sides have lengths 7a, 7b, 7c and 7d. The perimeter of new trapezoid is

$7a+7b+7c+7d.$

Use the distributive property for this expression:

$7a+7b+7c+7d=7(a+b+c+d).$

Since $a+b+c+d=14\ ft,$ then

$7a+7b+7c+7d=7(a+b+c+d)=7\cdot 14=98\ ft.$
