It takes 6 seconds for it to hit the ground.
0 = -5x²+20x+60
We can solve this by factoring. First factor out the GCF, -5:
0 = -5(x²-4x-12)
Now we want factors of -12 that sum to -4. -6(2) = -12 an -6+2 = -4:
0 = -5(x-6)(x+2)
Using the zero product property, we know that either x-6=0 or x+2=0; this gives us the answers x=6 or x=-2. Since we cannot have negative time, x=6.
Answer:
x= -24
Step-by-step explanation:
-1/4x-2/3x= -6+28
add -6 to 28 but since 6 is a negative its subtraction
-1/4x-2/3x=22
multiply all by 12
-3x-8x=264
add -3x to -8x
-11x=264
divide both sides by -11
x= -24
Answer: 2z + 6
Step-by-step explanation: Distribute the 2 to z and 3.
Answer:
-12, or 1 (see explanation)
Step-by-step explanation:
(-3)(+4)
Is the same as
4 * (-3)
which is
-12
Unless your problem is:
(-3) + 4
Then it is the same as
4 - 3
which is
1
