Determine # of solutions using discrimination
D = b^2 - 4 ac
D=8^2 - 4 x 6 x ( -10 )
D = 304
D > 0
The quadratic equation has 2 real solutions
You essentially have four triangles. The area of a triangle is: A=bh/2 (b=base length and h=height)
So the area is simply the sum of the four triangle areas...
A=(3*2)/2+(3*2)/2+(7*2)/2+(7*2)/2
A=20 ft^2
Answer:
1/2
Step-by-step explanation:
2/3-1/6
=4/6-1/6
=3/6
=1/2
Answer:
62.8, 63% if you around it off.
Step-by-step explanation: Do 49 Divided by 78, then times it by 100 to get your percentage. I just rounded it off to the nearest tenth and whole number just in case. Hope this helped!
