Hello,

Let's w the width , l the length, p the perimeter.

w=l-5
p=2(l+w)=2(l+l-5)=4l-10

4l-10=122
==>4l=122+10
==>4l=132
==>l=132/4
==>l=33
So w=33-5=28

Proof:
2*(33+28)=2*61=122

Find f(x) if it is known that f(x+3)=4x+12.
MArishka [77]

Solution:

we are given that

f(x+3)=4x+12

we have been asked to find f(x).

we can find the value of f(x) by re-writing the given function in the form of f(x+3) and thereafter we will replace (x+3) by x.

we can re-write the given function as below

f(x+3)=4(x+3)\\\\\Rightarrow f(x)=4x\\

Hence the expression representing f(x) is f(x)=4x+3.

A recipe calls for 2/3 cup of milk for 11 cookies. How many cups of milk are needed for 165 cookies​
gavmur [86]

Answer:

11 x 15 = 165, so to make 165 cookies, you would need 15 times the milk.

2/3 times 15 = 10

You would need 10 cups of milk to make 165 cookies
