Answer:
12x+4
Step-by-step explanation:
To find the perimeter of any shape you just have to take the sum of all the sides.
In this case you would write:
4x+2 (side 1) +2x (side 2) +4x+2 (side 3) +2x (side 4)
Now you just have to simplify the expression which would give you:
12x+4 (after collecting like terms)
So the final answer will be 12x+4

The manager of a home store is buying lawn chairs to sell at his store. Each pack of chairs contains 10 chairs. The manager will sell each chair at a markup of 20% of the wholesale cost, plus a $2.50 stocking fee.
a. Write an equation that represents the retail price of a chair, r, in terms of the wholesale price, w.
b. Use your equation to calculate the retail price of the chair if the wholesale price is $8.40.
c. Use your equation to calculate the wholesale price if the retail price is $13.30.
Answer:
$5
Step-by-step explanation:
a. The required equation is r = 0.2w + 2.5 + w. b. The retail price of a chair is $12.58 if the wholesale price is $8.40. c. The wholesale price is $44 if the retail price is $13.30.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
a. The retail price of a chair is the wholesale price plus the markup and stocking fee. The markup is 20% of the wholesale price, so we can represent it as 0.2w. The stocking fee is a fixed amount of $2.50, so we can add it to the markup and wholesale price to get the retail price.
The equation that represents the retail price of a chair, r, in terms of the wholesale price, w is:
r = 0.2w + 2.5 + w
b. To calculate the retail price of a chair if the wholesale price is $8.40, we substitute 8.4 for w in the equation:
r = 0.2(8.4) + 2.5 + 8.4
r = 1.68 + 2.5 + 8.4
r = 12.58
So the retail price of a chair, if the wholesale price is $8.40, is $12.58.
c. To calculate the wholesale price if the retail price is $13.30, we can solve the equation for w.
r = 0.2w + 2.5 + w
13.3 = 0.2w + 2.5 + w
10.8 = 0.2w + w
8.8 = 0.2w
w = 8.8 / 0.2
w = 44
So the wholesale price, if the retail price is $13.30, is $44.

Answer:
1: 7.5 2: 25 3: 14.2
Step-by-step explanation:
For all of these, you want to use the Pythagorean Theorem, which is a^2+b^2=c^2
1. you would have to plug in 13 for b, and 15 for c, because 15 is the hypotenuse
a^2+13^2=15^2
now, solve for a
a^2+169=225
225-169=56
a^2=56
to undo a squared, you have to take the square root of both sides
sqrt(56) is about 7.5
to check, you would have to plug in 7.5 for a
2. you would start off the same way, but this time we are solving for c
15^2+20^2=c^2
225+400=c^2
625=c^2
take the square root of 625
25 is your answer
if you want to check, plug in 25 for c
3. we are trying to find the hypotenuse again, so we are solving for c
5.1^2+13.2^2=c^2
26.01+174.24=200.25
200.25=c^2
take the square root once again
it is approximately 14.2
if you want to check, plug in 14.2 for c

Answer:
i believe the answer is 162 cubic inches
Step-by-step explanation:
as we know, the rectangles are conjoined but the easiest way to solve this is to separate them (so to speak) with that, let us pretend that we've cut them making two individual rectangles-
so rectangle one's dimensions are-
1, 8,9 (remember that the order the numbers are in is unimportant because the answer will still be the same no matter the order)
and rectangle two's dimensions are-
2,5,9
the formula for the volume of a rectangular prism is v=wlh
now we just need to plug in the information
rectangle one- v=1*8*9=72
rectangle two=2*9*5=90
now let us suppose we've re-conjoined the rectangular prisms-
(meaning we're going to add up the volumes for the total volume of the shape given in your problem)
72+90=162 cubic inches
good luck :)
i hope this helps

Answer:
C. 10
Step-by-step explanation:
There are 5 choices of carpet, and 2 choices of wallpaper. This means that there are only 10 possible outcomes.
The total number of possible outcomes when you select one color of wallpaper and one color of carpet is,

Given that;
You choose between red or yellow wallpaper,
And, orange, red, green, blue, or purple carpet.
Since, There are 2 wallpapers.
And, There are 5 carpets.
Hence, The total number of possible outcomes when you select one color of wallpaper and one color of carpet is,
⇒ ²C₁ × ⁵C₁
⇒ 2 × 5
⇒ 10
Thus, The total number of possible outcomes when you select one color of wallpaper and one color of carpet is, 10

Find the area of the composite figure. (Help With Explanation Pls)
Answer:
32cm²
Step-by-step explanation:
a=bh where b=base and h =hight
96 cm ^2
Formula for square is (base)(height)
(8cm)(8cm) = 64cm
Formula for triangle is (1/2)(base)(height) and we know that the base is 8 because it is on the side of the square.
(1/2)(4cm)(8cm) = 16cm
There are two triangles so 16 x 2 = 32 cm
Now add them
64cm + 32 cm = 96cm^2
