Let's solve your equation step-by-step.
−3x2−4x−4=0
Step 1: Use quadratic formula with a=-3, b=-4, c=-4.
x=
−b±√b2−4ac
2a
x=
−(−4)±√(−4)2−4(−3)(−4)
2(−3)
x=
4±√−32
−6
Answer:
No real solutions.
0.368 in expanded form would be...
0.000 + 0.300 + 0.060 + 0.008
or simply
.3 + .06 + .008
AC = 18
BC = 6x
AB = 2x + 4
Write and solve:
18 + 6x + 2x + 4
18 + 8x + 4 = 180
You can solve further:
18 + 8x = 176
8x = 158
x = 19 & 3/4
Not 100% sure what the question is asking, but hopefully this helps.
Answer:
Ben score -60
Sam score -20
Step-by-step explanation:
let Sam score be X
let Ben score be 3x
X+3x =80
4x =80
X=80/4
X =20 ........Sam score
Ben score=3x
=3 ×20
=60
2(12y) = 24y
(4y+6)(4y+6)= 8y+12
24y+8y+12
D. 32y + 12
