The quadratic formula is x=(-b+-sqrt(b^2-4(a)(c)))/2a
Using the quadratic formula, we get:
x=(-(-8)+-sqrt((-8)^2-4(15)(1)))/2(1)
x=(8+-sqrt(64-60))/2
x=(8+-sqrt(4))/2
x=(8+-2)/2
x=10/2 and x=6/2
x=5 and x=3
We could do it way faster by completing the square:
x^2-8x+15=0
(x-5)(x-3)=0
x=5 and x=3
Hope both methods make sense! BTW, the +- thing means add or subtract
Answer:
Step-by-step explanation:
A median bisects the side it intersects with, so the first step is to bisect FG.
Set the compass slightly larger than half of FG.
Put the point on F and draw a half circle that intersects FG and faces G.
Put the point on G and draw a half circle that intersects FG and faces F.
Draw a line through the intersections of the two half circles, and the intersection of that line with FG is FG's midpoint.
Connect the midpoint with E, and the connecting line is the median.
Answer:
B
Step-by-step explanation:
You would distribute the negative sign in front of -3. -3 would then become 3.
-6 (3)
Then you would place them on a line.

Answer:
7x+3y-z
Step-by-step explanation:
Starting off by separating the different variables, you should get:
(3x + 2x ) + (-z + 2z) + (3y)
Then you simplify in between the parentheses...
(5x) + (z) + (3y)
And you finally simplify the equation with only a single number of a certain variable to get your answer...
5x + z + 3y
