absolute value inequalities have 2 solutions

remember when you the negative to flip the inequality

5x+2 < 12   and 5x+2 >-12  

subtract 2 from each side

5x < 10   and 5x > -14

divide by 5

x<2 and  x > -14/5

-14/5 < x< 2

Answer:

-2 4/5 < x < 2

can somebody please help my friend, she has asked everyone she knows and nobody knows how to solve it. please help ty​
Nady [450]

Answer:

42

Step-by-step explanation:

First I'm going to assume that C and A are perpendicular.

Because its perpendicular, this creates a 90 degree angle which can be used to create the following equation.

90 = 6x - 6 + 5x + 8

Reduce

11x = 88

x = 8

We then plug in 8 into the equation 6x - 6 in order to solve for that angle.

6(8) - 6

If a gardener fences in the total rectangular area shown in the illustration instead of just the square area, he will need twice
Norma-Jean [14]

Answer:

He needs 5x+56 ft

Step-by-step explanation:

To find how much of fencing he needs , we find the perimeter of the given figure

All sides are equal in a square

To find perimeter of the square we add all the sides

4 sides we have for the square

one side is x, so perimeter of square = x+x+x+x= 4x

Now we find perimeter of rectangle

Opposite sides of rectangle are equal

Here for rectangle we consider only three sides

because fourth side is common for rectangle and square

So perimeter of the rectangle (with 3 sides) = 28 +x+ 28 = 56+x

Total fencing = perimeter of square + perimeter of rectangle

4x + 56 + x= 5x+56
