7x/x-4 * x/x+7
mutiply the numerators together
(7x)(x)= 7x^ 2
mutiply the denominators together
(x-4)(x+7)
(x)(x)(7)(x)= x^2+7x
(-4)(x)(-4)(7)= -4x-28
x^2+7x-4x-28
x^2+3x-28
Answer:
7x^2/x^ 2+3x-28
D the argument is not valid because the conclusion does not follow from the premises
we know that the multiplication comes first in the family then we start from left to right
4 x 5= 20
9-20 = -11
-11 + 6 = -5
there you go!
Answer:
Its acceleration will be 25m/s^2
Step-by-step explanation:
Distance the drag star moved from rest =400meters
Time taken =4 seconds
Speed= velocity= distance/time= 400m/4 s=100m/s
Acceleration at time 4 seconds will be;
Acceleration = Velocity/time=100/4=25m/s^2
Answer:
-4
Step-by-step explanation:
pproblems left is what you will use to determine your slope.
it's -4 because you subtract 4 each time it goes down.
