Wouldn’t it be the 7th root of 3? It’s a 30 60 90 triangle which means x=7 on that side so x on the bottom is the x root of three?
The distance around the bulletin board would be 20 feet, because you multiply 6ft 2x and 4ft 2x.
Answer:
{x,y} = {-2,2}
Step-by-step explanation:
Solve equation [2] for the variable y
7y = 7x + 28
y = x + 4
Plug this in for variable y in equation [1]
-8x + 4•(x +4) = 24
-4x = 8
Solve equation [1] for the variable x
4x = - 8
x = - 2
By now we know this much :
x = -2
y = x+4
Use the x value to solve for y
y = (-2)+4 = 2
Solution :
{x,y} = {-2,2}
and this intersects at only one point so your answer is A
Becase 3x9=27 27/100 would be the awnser and is already in simplest form
Angle 5x+7 is equal to the the sum of its remote interior angles, which we are given as x+15 and 6x-26. Therefore, 5x+7=x+15+6x-26. We will combine like terms to get 5x+7=7x-11. Move the 7x over to the other side by subtraction and the 7 to the other side by subtraction to get -2x = -18. That leaves us with an x value of 9. There you go!
