PLS HELP John was 3 5/8 feet tall when he was three years old. He is now 6 1/4 feet tall. How many feet did he grow in total?
Prediction:_
Expression: _
Simplify

2 5/8

Step-by-step explanation:

When you convert both of the fractions into improper fractions you get 29/8 and 25/4 so you subtract because it asked you how many feet did he grow so 25/4 - 29/4 = 21/8 but since it is improper you have to turn it into a mixed fraction which will be 2 5/8. So he grew 2 feet with 5/8 inches. Hope this helped.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

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
