Simplify. (-2)-3 -8 - 8 user: simplify. 6x-2

Vinvika [58]

If you would like to simplify (-2)-3 -8 - 8 and 6x - 2, you can do this using the following steps:

(-2)-3 -8 - 8 = - 2 - 3 - 8 - 8 = - 5 - 8 - 8 = - 13 - 8 = - 21

6x - 2 = 2 * (3x - 1)

The correct result would be - 21 and 2 * (3x - 1).

NEED HELP ASAP!!!!!!!!!!!

Answer:

a. $\frac{x + 3}{21}=\frac{x + 1}{15}$

b. x = 4 (see steps below)

Step-by-step explanation:

Since the two polygons are similar, the sides are proportional to each other. Using a proportion, you can solve for 'x' using cross-multiplication and division:

$\frac{smaller}{larger}=\frac{x + 3}{21}=\frac{x + 1}{15}$

Cross-multiply: 15(x + 3) = 21(x + 1)

Distribute: 15x + 45 = 21x + 21

Subtract '15x' from both sides: 15x + 45 - 15x = 21x + 21 - 15x or 45 = 6x + 21

Subtract '21' from both sides: 45 - 21 = 6x + 21 - 21 or 24 = 6x

Divide by 6 on both sides: 24/6 = 6x/6

Solve for x: x = 4
