Answer:
x = 1 or x = −6
Step-by-step explanation:
Step 1: Subtract 18 from both sides.
3x2+15x−18=18−18
3x2+15x−18=0
Step 2: Factor left side of equation.
3(x−1)(x+6)=0
Step 3: Set factors equal to 0.
x−1=0 or x+6=0
x=1 or x=−6
Answer:
Step-by-step explanation:
1 tyres time to install is 56/4=14
which means it takes 14 minutes to install one tire.
so 12 tires would be 12 x 14 which is 168 minutes
A) 168 minutes
1 tire = 14 min
42 min/14 min=3
B) 3 tires
Answer: The answer is not -7 it is in fact -31.
Step-by-step explanation:
5 - ( 6^2 ) / 4 - 3
6^2 = 36
5 - ( 6^2 ) = -31
4 - 3 = 1
5 - 36 / 1 = -31 / 1 = -31
So anything divided by 1 is = to itself.
I cant see the model but 2/3 is the same as 4/6
