Amelia has $100 in her savings account and plans on solving $20 per week. Write an equation to represent this situation.

100 + (20 x W)

Step-by-step explanation:

100 is the money that is already in the account so it will just be added to what she saves afterward. W stands for the weeks she saves, which will be multiplied by 20 since it is what she will save per week.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
