Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
The length is 3x + 7
The width is 2x + 2
The perimeter is
<h3>2( 3x + 7) + 2( 2x + 2)</h3>
Simplify
6x + 7 + 4x + 4
Group like terms
6x + 4x + 7 + 4
We have the final answer as
<h3>10x + 11</h3>
Hope this helps you
Answer
f(x)=9/x , g(x) = x / x + 1 = 9/2
Step-by-step explanation:
Answer:
A. 40
Step-by-step explanation:
Q1 - 40
Q2 - 65
Q3 - 80
And 90 is max
So 40 is the correct answer.
1 person make 3 cakes.
40 people make 40 x 3 = 120 cakes.
15% were chocolate = 15% x 120 = 0.15 x 120 = 18
Answer: There were 18 chocolate cakes made for bake sale.

Taking natural logs of both sides, we get
0.015t=ln 3
t = ln 3/0.015 = 73.24
The answer is 73.24 years.
