Answer: Width = 5 inches
Concept:
Here, we need to know the idea of the perimeter.
A perimeter is a path that encompasses/surrounds/outlines a shape.
Perimeter of rectangle = 2 (w + l)
w = width
l = length
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
w = w
l = 3w - 2
P = 36 inches
<u>Given formula</u>
P = 2 (w + l)
<u>Substitute the value into the formula</u>
36 = 2 (w + 3w - 2)
<u>Simplify values in the parentheses</u>
36 = 2 (4w -2)
<u>Divide 2 on both sides</u>
36 / 2 = 2 (4w - 2) / 2
18 = 4w - 2
<u>Add 2 on both sides</u>
18 + 2 = 4w - 2 + 2
20 = 4w
<u>Divide 4 on both sides</u>
20 / 4 = 4w / 4
w = 5
Hope this helps!! :)

Answer:
Step-by-step explanation:
For the first question: You need to multiply 20 by 0.05 to find the sales tax amount in dollars, which gives you $1. The sales tax is equal to $1.
For the second question: To find the total cost, add $1 to $20 to get $21 as the total cost for the shirt.
F(1) = 0 tells you that wherever you see an x, you put in a one. When you do, the answer comes out as 0
So one of he factors for f(x) is
f(x) = (x -1) * g(x)
If you put an 1 into (x - 1) you get (1 - 1) = 0
The whole thing goes to zero when that happens.
If you split up g(x) so that when x = - 2, the whole polynomial goes to 0 just as what happened with x = 1
f(x) = (x - 1) (x + 2) * h(x)
When x = 3 the same thing happens.
f(x) = (x - 1)(x + 2)(x - 3) and that's your complete answer.
Answer:
12/5 or 2 2/5
Step-by-step explanation:
reduce the numbers with the greatest common denominator 2.
4×3/5
4/1 × 3/5
multiply.
4×3=12
1×5=5
12/5
