PLEASE HELP ME I WOULD APPRECIATE IT SO MUCH AND I GIVE BRAINLIEST

1.) a=4

3a=12

Divide by 3 on each side

a=4

2.) b=5.6

b+3.3=8.9

 -3.3  -3.3

b=5.6

3.)c=4

1=1/4c

Multiply by 4 on each side

c=4

4.) e=3.2

2e=6.4

Divide by 2 on each side

e=3.2

126 maybe. sorry

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
