Answer:
Step-by-step explanation:
Given
Required
Find n
Simplify (n + 1)!
Factorize
Divide both sides by n!
Open brackets
Collect like terms
Multiply both sides by -1
Answer:
Step-by-step explanation:
So we have : c + 2.5 < 4.3
And it's asking whether c = 1.8 is a solution.
Substitue c = 1.8 in, we get :
1.8 + 2.5 < 4.3
4.3 < 4.3 (not true)
So, c = 1.8 is NOT a solution.

Explanation:
Replace every copy of x with -1. Then use PEMDAS to simplify
F(x) = -x^3 - x^2 + 1
F(-1) = -(-1)^3 - (-1)^2 + 1 ... every x has been replaced with -1
F(-1) = -(-1) - 1 + 1
F(-1) = 1 - 1 + 1
F(-1) = 0 + 1
F(-1) = 1
