Answer:

(P/2) - W = L

Step-by-step explanation:

P = Perimeter

W = Width

L = Length

Formula of Perimeter

=> P = 2L + 2W

Now, let's simply that formula to make L alone.

=> P/2 = 2L/2 + 2W/2

=> (P/2) = L + W

=> (P/2) - W = L + W - W

=> Length = (P/2) - W

For example, let's take the perimeter of a rectangle is 14cm. Its width is 2cm. Length is L

Using the formula,

=> (P/2) -  W = L

=> (14/2) - 2 = L

=> 7 - 2 = L

=> L = 5

Let's plug in our answer.

=> 2(5) + 2(2) = 14

=> 10 + 4 = 14

=> 14 = 14

So, our formula is correct.

From point A to C, which is the length of the entire line, it's 3x + 1.
AB = 2x + 4
BC = 10

This means that AB + BC = AC

All you have to do is plug in the equations.

(2x + 4) + (10) = (3x + 1)
2x + 14 = 3x + 1
2x + 13 = 3x
13 = x

Now plug in the value of x (13) into the AC equation (3x + 1).
AC = 3(13) + 1
AC = 39 + 1
AC = 40

The answer is:
a. 40

AVprozaik [17]

Answer:

B

Step-by-step explanation:

The volume (V) of a rectangular prism is calculated as

V = length × width × height

Calculate the volume of each prism

Q → V = 8 × 4 × 5 = 60 ft³

R → V = 6 × 7 × 12 = 504 ft³

S → V = 4 × 10 × 12 = 480 ft³

T → V = 2 × 13 × 5 = 130 ft³

Prism R has the greatest volume → B
