For this case we have the following equation:
The variables are:
t: time in hours
d (t): distance traveled in miles.
We evaluate the distance traveled after 4 hours.
So we have that for t = 4:
Answer:
d (4) = 68
This means that after 4 hours Joanna cycled for 68 miles total
Answer:
(6x^2+1) • (2x^2+3) =
12x^4 + 18x^2 + 2x^2 +3 =

Step-by-step explanation:
Answer:
y=6
Step-by-step explanation:
divide the total area by 5 to get the area of the square
180/5= 36 cm²
the area of a square is y²
so y²=36⇒ y= 6
