Answer:
This is english not math but.....
If it is warm outside, then it is summer.
Step-by-step explanation:
Basically just switch the terms and make it grammatically correct.
x^2 - 4
------------------------------
x + 7 | x^3 + 7x^2 - 4x - 28
x^3 + 7x^2
------------------
0 - 4x - 28
-4x - 28
-------------
0
Now we know that
x^3 + 7x^2 - 4x - 28 = (x^2 - 4)(x + 7)
x^2 - 4 can be factored since it is the difference of two squares.
x^2 - 4 = (x + 2)(x - 2)
The complete factoring is:
x^3 + 7x^2 - 4x - 28 = (x +2)(x - 2)(x + 7)

Answer:
715
Step-by-step explanation:
All you do is 465 + 250
465 + 250 is 715
1. A = 2ab + 2ac = 2bc
2. A = 2b(a +c) + 2ac
3. 2b(a + c) = A - 2ac
4. b = (A - 2ac) / 2(a + c)
