He drove 140 miles you take 245 divide by 7 then times by 4
(
+ 4)(
- 4)
To solve this question you must FOIL (First, Outside, Inside, Last) like so
First:
(x^2 + 4)(x^2 - 4)
x^2 * x^2
x^4
Outside:
(x^2 + 4)(x^2 - 4)
x^2 * -4
-4x^2
Inside:
(x^2 + 4)(x^2 - 4)
4 * x^2
4x^2
Last:
(x^2 + 4)(x^2 - 4)
4 * -4
-16
Now combine all the products of the FOIL together like so...
x^4 - 4x^2 +4x^2 - 16
Combine like terms:
x^4 - 4x^2 +4x^2 - 16
- 4x^2 +4x^2 = 0
x^4 - 16 <<<This is your answer
Hope this helped!

Answer:
f(x)=100x
Step-by-step explanation:
Answer:
6x^2-7x-20
Step-by-step explanation:
Use the FOIL method: (a+b)(c+d)= ac+ad+bc+bd
6x^2-15x+8x-20
Collect like terms:
6x^2+(-15x+8x)-20
Simplify:
6x^2-7x-20
