Answer:

width = 11, len = 19

Step-by-step explanation:

length = 2w - 3

l = length

w = width

2(length) + 2(width) = perimeter

2(2w - 3) + 2(w) = 60

6w -6 =60

w = 11

len = 2(11) - 3

What is the slope of the line passing through (1, 2) and (3, 8)?

saveliy_v [14]

Answer:

Option C is correct.

Step-by-step explanation:

Points given are

(1,2) and (3,8)

The formula used for slope is:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

x₁ = 1, x₂=3, y₁=2 and y₂=8

$m=\frac{8-2}{3-1}\\m=\frac{6}{2}\\m=3$

So, slope =3

Option C is correct.

Answer: x = 3. the length of side ST is 14.

Step-by-step explanation:

Since both sides are equal, we can use the equation 3x + 5 = 5x - 1.

To start the problem, we subtract 3x from each side which makes our equation 5 = 2x - 1.

The next step would be to simplify the equation by adding 1 to each side which makes our equation 6 = 2x.

We then need to simplify the equation to x = 3.

This means the answer to 9 is x = 3.

For the next problem, since we already know the value of x, we substitute its value which in this case would be 3. This leaves us with an equation of 9 + 5, which equals 14.

This means the length of side ST is 14.
