If two triangles are similar (in the geometric sense), then the sides must be proportional.
Answer:
16x^3 - 6x + 7/2
Step-by-step explanation:
32x^4 - 12x^2 + 7x by 2x
32x^4/2x = 16x^3
- 12x^2/2x = - 6x
7x /2x = 7/2
So
32x^4 - 12x^2 + 7x by 2x =
16x^3 - 6x + 7/2
Answer:
divide
Step-by-step explanation:
You are looking for a speed in miles per hour, so start by converting 90 minutes into hours.
90/60 = 1.5
90 minutes = 1.5 hours
speed = distance/time = (105 miles)/(1.5 hours) = 70 mph
