14=-(p-8) <br> how do i find p
Xelga [282]

Answer:

p=-6

Step-by-step explanation:

14 = -(p-8)   (distribute negative into parentheses)

14 = p(-1) -8(-1)

14 = -p + 8   (subtract 8 from both sides)

14 - 8 = -p

6 = -p   (multiply both sides by -1 and rearrange)

p = 6(-1) = -6

Simplify the following expression 2x-4t+7y-16
lawyer [7]
OK so to solve this we will subtract 16x from 2x to get -14x
-14x - 4y + 3x^2 + 7y
add - 4y and 7y to get 3y
-14x + 3x^2 +3y
and then to simplify we are going to move the -14x
3x^2 +3y - 14x

The length of a rectangle is 3 inches more than its width.
BlackZzzverrR [31]

Answer:

X=15

Step-by-step explanation:

Ignore the increase for equasion. This is factored in but irellevent. Orignal x value is 13, but increases to 15, and orignal x value is not needed for this equasion. (its there to confuse you)

L+L+W+W=66.

(w+3) +(w+3) +w +w = 66

(4xw) + 3 +3= 66

4 x w = 66 -3 -3

4 x w =60

60/4= 15.

L= 15+ 3 =18

W = 15.

W + W + L + L

15 + 15 + 18 +18 =66
