Answer:
a. (x^3+8)(x^2-4)
b. x=1 and x=1/2
Step-by-step explanation:
a. (x^3+8)(x^2-4) = x^5-4x^3+8x^2-32 [foil method: first,outside,inside,last]
b. use quadratic formula: -b +/- square root b^2-4ac / 2a
2=a; -3=b; 1=c
-(-3) + square root (-3)^2 - 4(2)(1) / 2(2)
3 + 1 / 4 = 4/4 = 1
3 - 1/4 = 2/4 = 1/2

Answer:
1668
Step-by-step explanation:
a small apartment is 834 square feet so if you x2 I think it will be 1,668
Here is the solution based on the given problem above.
Given: 25miles/hour = speed of the cyclist
? = speed in feet/second
1 mile = 5280 feet
1 hour = 3,600 seconds
In order to get the result, we need to get first how many feet is 25 miles.
so, 25 miles is equivalent to 132,000 feet.
and 1 hour = 3,600 seconds
So, it is 132,000 feet/3,600 seconds. Let us simplify this.
So the answer would be 36.67ft/second.
I hope this is the answer that you are looking for.
