A line that is parallel to a side and intersects the other two siddes divides the sides proportionally.
Set up the proportion
2/x+1 = x/x+6
Multiply means and extremes
2x+12= x^2+ x
Solve to get your answer.
Answer:
±2√3
Step-by-step explanation:
Equation :
x² -4 = 8
x² -12 = 0
Using the quadratic formula then simplifying gives you :
±2√3
I know this lacks explanation but please brainliest
Answer:
x=1/4
Step-by-step explanation:
4x+5=4+2
4x+5=6 simplify
4x+5-5=6-5 subtract from both sides
4x=1 simplify
(4x/4)=1/4 divide both sides
x=1/4 final answer
You need to convert the second equation to slope/intercept form. The first equation is in that form already. Then you can compare slopes.
-6x + 8y = 14
8y = 6x + 14
y = (3/4)x + 14/8
SO THE SLOPE IS 3/4 which is the same as slope of equation 1
Therfore they are parallel.
