<span>x = –4c
</span>if c = -2 then x = -4(-2) = 8
I believed you had a typo, function should be f(x) = -3x^2 - 4x
so
<span>f(x) = -3x^2 - 4x
</span>f(x) = -3(8^2) - 4(8)
f(x) = -3(64) - 32
f(x) = -192 - 32
f(x) = -224
answer
<span>C.
–224</span>

Use the information to form a ratio... 6:8 or 6/8. Now set it equal to a ratio per 100...
6/8 = x/100
Cross multiply
8x = 600
x = 600/8
x = 75
75% have moons
Answer:
60
Step-by-step explanation:
m(ADB) + m(BDC) = 90°
(3x+9) + (2x -4) = 90°
5x + 5 = 90°
5x = 85
5x/5 = 85/5
x = 17
m(ADB) = 3x + 9
3.17 + 9 = 51 + 9 = 60
Hope this helps ^-^
