How do you solve this?

Answer:

Step-by-step explanation:

Since you know that JK + KL = JL, this would be:

27 + 3x - 1 = 5x + 2

Now, solve this equation:

combine like terms first

$26+3x=5x+2$

subtract 3x from both sides

$26 = 2x+2$

subtract 2 from both sides

$24 = 2x$

divide both sides by 2

$12 = x, x= 12$

Since you want to find JL and JL = 5x + 2, plug x = 12 into that equation.

$JL = 5* 12 + 2\\JL = 60 + 2\\JL = 62$

-8 ≤ x ≤ 2

Step-by-step explanation:

We assume you intend the absolute value equation ...

$|x+3|\le5\\\\{-}5\le x+3\le5\qquad\text{rewrite as a compound inequality}\\\\\boxed{{-}8\le x\le2}\qquad\text{subtract 3}$

The formula for finding the perimeter of a rectangle with length, l, and width, w, is P = 2l + 2w.

user100 [1]

Perimeter of a rectangle:
P=2I+2W=2(I+w)

But if the length and width of a rectangle are both double, then we would have:
Length=2I
width=2w

Therefore, its perimeter would be:
P=2(2I+2w)=4(I+w)

the old perimeter was P=2(I+w) and the new perimeter is P=4(I+w)=2[2(l+w)]
There the perimeter is twice as great.

Answer: C) the perimeter is twice as great.
