Step-by-step explanation:
Hi there!
To multiply, we need to use f.o.i.l:
(x + 8)(x - 7)
= x * x - 7 * x + 8 * x - 8 * 7
= x^2 - 7x + 8x - 56
= x^2 + x - 56
Hope this helps!
Multiply it out.
f(x) = (2x +1)(x² -1) . . . . . . recognize the factoring of the difference of squares
f(x) = 2x³ +x² -2x -1

omg im still dont no

The distance that Kirsten and Molly need to bike on their third day is obtained by subtracting the sum of the distances they have traveled after two days from the length of the entire route.
distance left = 156 miles - (64 miles + 45 miles)
= 47 miles
Thus, Kirsten and Molly need to bike 47 miles on their third day.
