5.6 times the sum of 4 and a number p

22.4 + 5.6p

Step-by-step explanation:

5.6 x (4 + p) = ?

Or it looks like this:

5.6 (4 + p) = ?

We need to distribute:

5.6 x 4 and 5.6 x p

5.6 x 4 = 22.4

5.6 x p = 5.6p

Now, you have 22.4 + 5.6p

We leave it like this because you cannot simplify the equation any more.

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
