Answer:

A n=-16

Step-by-step explanation:

(3n+3)/5 = (5n-1)/9

Using cross products

9* (3n+3) = 5(5n-1)

Distribute

27n+27 =25n-5

Subtract 25n from each side

27n-25n +27 = 25n-25n -5

2n +27 = -5

Subtract 27 from each side

2n +27-27 = -5-27

2n = -32

Divide each side by 2

2n/2 = -32/2

n = -16

P^2 - 4p - 32 / p + 4, simplify the rational expression. state any restrictions
dusya [7]

Answer:

The correct answer is: p - 8 ∧ restriction p ≠ -4

Step-by-step explanation:

(p² - 4 p - 32) / ( p + 4)

The existence of this rational algebraic expression is possible only if it is:

p + 4 ≠ 0  => Restriction is p ≠ -4

(p² - 4 p - 32) / ( p + 4) = (p² - 8 p + 4 p - 32) / (p + 4) =

= (p (p -8) + 4 (p -8)) / (p + 4)= (p - 8) (p + 4) / ( p +4) = p - 8

God with you!!!

A customer decides to build a fence around the backyard. The yard is rectangular, and with the house an equal distance from both
DerKrebs [107]

Answer:

D). 290 feet

Step-by-step explanation:

Length of the yard = 65 feet

Width of the yard = 80feet

The Perimeter of the yard = 2(l + b)

                                           = 2 * (65 + 80)

                                            = 2 * 145

                                             = 290 feet

∵ Fencing required = 290 feet

Thus, <u>option A</u> is the correct answer.
