Three vertices of a rectangle are at (3,,8), and (8,8).what is the perimeter of the rectangle what i'm looking for is how many units

22 units

Step-by-Step Explanation

Well, before we can find the perimeter we have to find the last vertices of the rectangle. (3,2) is 6 units down from (3,8), so just go down 6 from (8,8) and you'll arrive at (8,2). Since this rectangle is pretty simple you can just count the units to find the length (12) and width (10).

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
