Both terms have a
in common, so we can pull it out. The factored form will be
times whatever is left after pulling it out.
In the first term, we will have just 8 left since everything else in the term is factored out.
The second term has a
left. Notice that both of these terms no longer have a negative sign since the negative was factored out.
The answer is
Answer:last one
Step-by-step explanation:
last one
Answer:
x = 12
Step-by-step explanation:
Solve for x:
(-3 x)/2 - 9 = -27
Put each term in (-3 x)/2 - 9 over the common denominator 2: (-3 x)/2 - 9 = (-18)/2 - (3 x)/2:
(-18)/2 - (3 x)/2 = -27
(-18)/2 - (3 x)/2 = (-3 x - 18)/2:
(-3 x - 18)/2 = -27
Multiply both sides of (-3 x - 18)/2 = -27 by 2:
(2 (-3 x - 18))/2 = -27×2
(2 (-3 x - 18))/2 = 2/2×(-3 x - 18) = -3 x - 18:
-3 x - 18 = -27×2
2 (-27) = -54:
-3 x - 18 = -54
Add 18 to both sides:
(18 - 18) - 3 x = 18 - 54
18 - 18 = 0:
-3 x = 18 - 54
18 - 54 = -36:
-3 x = -36
Divide both sides of -3 x = -36 by -3:
(-3 x)/(-3) = (-36)/(-3)
(-3)/(-3) = 1:
x = (-36)/(-3)
The gcd of -36 and -3 is -3, so (-36)/(-3) = (-3×12)/(-3×1) = (-3)/(-3)×12 = 12:
Answer: x = 12
Answer:
Choice C
Step-by-step explanation:
1/2 x < 4 Isolate x by multiplying both sides by 2:-
x < 8
Answer:
hope this helps!
Step-by-step explanation:
From y(t) = −16t^2 − 3t + 300 find at what time the fertilizer hits the ground (has height 0)
0 = −16t^2 − 3t + 300
Using the quadratic formula (minus b plus or minus the square root of b squared minus 2 a c over 2 a) you get
t = 4.237 seconds
So the horizontal distance is 85t = 85 * 4.237 = 360.145 feet
