4 to the fourth power is the same as
4×4×4×4=256
I hope I've helped!
The discriminant:
D = b² - 4 a c = 7² - 4· 3 · 2 = 49 - 24 = 25
D > 0 This function has 2 x-intercepts ( 2 zeroes ).
x 1 = (-7+5)/6 =-1/3
x 2 = (-7-5) / 6 = - 2
The formula of an area of a rectangle:
A = lw
l - length, w - width.
We have w = 56 mi and l = 157 mi. Substitute:
<h3>A = (56)(157) = 8,792 mi²</h3>
Answer:
3 hours
Step-by-step explanation:
First we can find how much money you had to pay for keeping the skates for the additional hours:
$7.70-$3.95=$3.75
Now we find how many hours you kept the skates...
$3.75/$1.25 per hour=3 hours
