Melissa got two puppies, Ben and Sadie. When she got them, Sadie was 5 pouds less than Ben. If Sadie's weight quadrupled after one year, write an expression using parentheses to show Sadie's weight.

4(B - 5) = S

Step-by-step explanation:

B = Ben

S = Sadie

We know that Sadie was 5 pounds less than Ben, with this information, we can create the expression B - 5 = S.

We are then told that after one year, Sadie's weight quadrupled (4), to find out how much Sadie weighs, we need to multiply her current age by 4, but we do not know her age yet, so use the equation we have already.

B - 5 = S

Since we are looking for her age quadrupled, we need to multiply the left side of the equation by 4.

[4(B - 5) = S]

This also fits us having to use parenthesis.

2? if not the correct answer you might need to provide more information

step-by-step explanation:

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
