Answer:
a) A = 48x + 24
b) Yes
Step-by-step explanation:
a) The area of a rectangle is found using A = l*w. Substitute l = 6x + 3 and w = 8 to find the area.
A = (6x + 3)(8) = 48x + 24
b) Repeat the same process with the formula A = l*w. Substitute l = 4x + 2 and w = 12.
A = (4x+2)(12) = 48x + 24
The areas are the same.
Answer:
x+(x+4)=52
Step-by-step explanation:
Let's name the smaller number x.
The greater number would then be (x+4).
<em>The sum of two numbers means we are adding them together.</em>
<u>The equation we could then set up would be:</u>
x+(x+4)=52
<em>Now we can solve the equation to find the two numbers if needed.</em>
<u>Here is how:</u>
x+x+4=52
Combine like terms.
2x+4=52
Subtract 4 from both sides.
2x=48
Divide both sides by 2
x=24
The smaller number is 24.
24+4=28
The larger number is 28.
See the attached picture.
First calculate the length of each side.
Using the side length multiply by the number of sides to find the perimeter.
Then the area is 1/2 x perimeter x apothem.
Answer:
3/8 is the correct answer.
