after 6 hours Al and Ben will be 180 miles apart.
(22 * x) + (8 * x) = 180
x = 6 hours
Answer:
D
Step-by-step explanation:
If you plot both points on a graph you can see the angle is much larger than 58 degrees so it must be 122 degrees. The square root of 13 is less than 4, and you can see that the two points are further than four units apart. Sorry for a non-mathematical explanation, this is just how I solve these things lol.
In this problem, we're going to use the 'PEMDAS' method.
First, we're doing the problem in the parenthesis.
44 - 4 = 40
Next in PEMDAS, we need to do the exponent.
6² = 6 x 6 = 36
Then we would do multiplication, but there is nothing to multiply so we move onto division.
40 / 2 = 20
Now we would add, but there is nothing to add so we move onto subtraction.
20 - 36 = -16
Our final answer would be -16.
Hope this helps!~
Answer:
3/10 ÷ (-4/5) = 3/8 and then for the bottom one is -1 7/8 and for the one in the right is 6 2/5
First, you need to factor the polynomial.
I'll use the trial and error method.
6x^2 - 5x - 6 = 0
6 has factors
6 and 1
3 and 2
I'll try 3 and 2 first.
(3x )(2x ) = 0
Now we need to factor -6.
-6 factors into
-1, 6
-6, 1
-2, 3
-3, 2
Now we need to see if one of these pairs of factors placed correclty will factor the trinomial.
(3x + 2)(2x - 3) = 0
That did it.
Now we use the zero factor property.
3x + 2 = 0 or 2x - 3 = 0
3x = -2 or 2x = 3
x = -2/3 or x = 3/2
