Answer:

x=1

Step-by-step explanation:

-31+(-4x) = -5+(-5)(1+5x)

-31-4x = -5+(-5)+(-25x) : Adding a negative is the same as subtracting and I distributed the -5

-31 = -5 + -5 -21x : added 4x to both sides

-31 = -10 -21x : added -5 and -5

-21 = -21x : added 10 to both sides

x=1 : divided both sides by -21, division of 2 negatives is a positive

A5 inch x 7 inch photograph is placed inside a picture frame. Both the length and width of the frame are 2x inches larger

My name is Ann [436]

Answer:

8x+24

dimensions of the photograph

length - 7 inch

width - 5 inch

dimensions of the photo frame is 2x larger than both width and length

length - 7 + 2x

width - 5 + 2x

the perimeter is sum of all 4 sides

Perimeter = 2(7 + 2x) + 2(5 + 2x)

= 14 + 4x + 10 +4x

= 24 + 8x

correct answer is 8x+24
