What is the value of x?
Please help

x = 4

Step-by-step explanation:

Assuming these are similar triangles,we can use ratios to solve

3x+8        25

=

4               5

Using cross products

5(3x+8) = 4*25

Distribute

15x +40 = 100

Subtract 40 from each side

15x+40-40 = 100-40

15x= 60

Divide each side by 15

15x/15 = 60/15

x =4

First, find the scale factor between both triangles.

25 / 5 = 5

15 / 3 = 5

Second, multiply to find the missing side length.

4 * 5 = 20

Third, solve for x.

3x + 8 = 20

3x + 8 - 8 = 20 - 8

3x = 12

3x/3 = 12/3

x = 4

Best of Luck!

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
