C) A =
Step-by-step explanation:
First, read through what the question is asking.
Now, read it again, but slowly and take in everything it is saying (Don't read into it too slowly, or else you will over-complicate the problem and get frustrated - told from experience :) )
Alright, 4 less than 3 times the width. So, lets rearrange this and give width a variable (w).
So, the length is equal to:
l = 3w - 4
and the width is equal to:
w = w
The area of a rectangle is A = l * w
Let's plug in the values.
A = (3w - 4) * w
Now, simplify:
A =
A = is your final answer.

Answer:
69%
Step-by-step explanation:
If the diameter is increased by 30%, it is effectively multiplied by the factor ...
1 + 0.30 = 1.30.
Volume is proportional to the square of the diameter, so the larger can's volume is ...
(1.30)² = 1.69
times that of the smaller can. That is, 0.69 = 69% of the volume of the smaller can has been added to make the volume of the larger can.
The volume of the larger can is 69% more than that of the smaller can.

Step-by-step explanation:
° put the value of x at the place of x to get y , put value of y to get x.
° x = -4
y = -2x + 3
y = -2(-4) + 3
y = 8 + 3 = 11
° x = -1
y = -2(-1)+3
y = 2 + 3
y = 5
• y = 3
y = -2x + 3
3 = -2x + 3
0 = -2x
x = 0
• y = -3
-3 = -2x + 3
-6 = -2x
x = 3
