Hello! So both numbers are negative, so the answer will definitely be positive. All you have to do is multiple straight across. 4 * 7 is 28 and 9 * 9 is 81. That’ll make the fraction 28/81. The product is 28/81.
Answer: the answer is line 2
Step-by-step explanation:
Answer:

Step-by-step explanation:
we have given x'=(24-16)x=8x
x' denotes the differenation
differentiation is performed with respect to t
by variable separable method we can write

on integrating both side

(property of log )
so the solution for x will be 
-32+<u>50</u> =2(x^2+10x+25)
18=2(x+5)^2
9= (x+5)^2
+-<u /> <u>3</u> = x+5
x= -2 or x= <u>-8</u>
Answer: 5hrs = 200miles.
if you divided 120 by 3 you will get 40 thats how many miles it in 1 hour.
Step-by-step explanation:
1 hour = 40
