Answer:

I'm not sure what you mean by set up the equation, however X=6

Step-by-step explanation:

first you add the 7x with 21x

so you have 28x+23-11=180

second step is subtracting 11 from 23

so now you have 28x+12=180

the third step is 28x+12-12=180-12

so you have 28x=168

and the you divid both sides by 28 and you get 6

When x pounds of force is applied to one end of a lever that is L feet long, the resulting force y on the other end is

nadezda [96]

The question is worded poorly, but it looks like you have a lever in equilibrium, with a force x at a distance d from the fulcrum, and a force y at a distance L - d from the fulcrum. You already have the equilibrium formula for this situation:

xd = y(L - d)

If you know x, y, and d, you can solve for the length L.

Ivan used coordinate geometry to prove that quadrilateral EFGH is a square.

Gelneren [198K]

Answer:

(A)Segment EF, segment FG, segment GH, and segment EH are congruent

Step-by-step explanation:

Step 1

Quadrilateral EFGH with points E(-2,3), F(1,6), G(4,3), H(1,0)

Step 2

Using the distance formula

$Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
