Writing equivalent equations help you solve system of equations because it sets it up for being broken down part by part.
Answer:
first one : (7+12+3+4+4+8)*2=76
Answer:
Ans: (-5, 5)
-5 < x < 5
Step-by-step explanation:
Standard form: f(x) = x^2 - 25 < 0.
First solve x^2 - 25 = 0 --> x = +- 5
Use the algebraic method to solve f(x) < 0. Between the 2 real roots (-5) and (5), f(x) < 0, as opposite in sign to a = 1.
Answer by open interval: (-5, 5)
Answer:
Negative
Step-by-step explanation:
- –54 ÷ 6 = -9
