Ok the answers is 6 but don’t be mad if I’m wrong
Answer:
- construct PQ
- construct circles of radius PQ centered at P and Q
- label one of the points of intersection R
- Construct PR and QR
Step-by-step explanation:
You should actually do this some time. It will help you understand the construction process and help you remember the steps. It may even help you figure out why it works.
Answer:
x= 6 ± √31
Step-by-step explanation:
x^2-12x=-5
x^2 -12x +36= -5 +36
(x -6)^2= 31
√(x -6)^2= ±√31
(x-6)= ±√31
x= 6 ± √31
Answer:
x=-2, y=-6
Step-by-step explanation:
Simple substitution.
Since y is isolated in one of the equations already, you can plug it into the second equation.
x - 2(3x) = 10
x - 6x = 10
-5x = 10
x = -2
Sub. x = -2 into 3x = y:
3(-2) = y
y = -6
