If we have the speed of 18 miles per second, 18miles/s
to find out what is the speed in 1 minute we will need to multiply 18 by 60, as there are 60 seconds in 1 minute
18 miles..............................1 second
?miles..................................60 seconds(1min)
18*60=1080 miles
we have 1080 miles/minute
in 2 minutes we have 1080*2=2160 miles
hope it helps
Answer:
x = 2
Step-by-step explanation:
the formula for this problem is
Area = 1/2 base x Height
step 1) plug in what we know
5 = 1/2 base(5)
step 2) switch sides
1/2 base x 5 = 5
step 3) divide both sides by 1/2 x 5
= 
step 4) Simplify
step 5) Simplify
step 6) now you have gotten the answer<u> x = 2</u>
(x^4 - 9)(x^3 + 9)
This is a binomial * binomial. Use the FOIL method for multiplying.
First, outer, inner, last.
x^4 * x^3 = x^7
x°^4 * 9 = 9x^4
-9 * x^3 = -9 x^3
-9 * 9 = -81
Putting it back together.
x^7 +9x^4 -9x^3 - 81
