Answer:
10028.6 ft/hr
Step-by-step explanation:
speed = distance / time
234 Inches = 19.5 Feet
7 seconds = 0.00194444 hrs
so using the formula : 19.5 / 0.00194444 = 10028.6 ft/hr
Answer:
D.540
if im wrong sorry
Step-by-step explanation:
The answer is 1719.09 because that’s the total
a(x+1)(x-1)+b(x-2)(x+1)+(x+1)^2=9x^2-x-10
(x+1)(a(x-1)+b(x-2)+(x+1))=(x+1)(9x-10)
a(x-1)+b(x-2)+x+1=9x-10
Now this equation is much simpler!
(a+b)x-a-2b+x+1=9x-10
(a+b)x-a-2b=8x-11
(a+b-8)x-a-2b-11=0
a+b-8=(a+2b-11)/x
I can't solve it 3 variables and 1 equations means infinite answers so yea.
