Answer:
Basically when you use parantheses it protects that number from becoming negative...
-10^2 is -100 but with paranthesis is 100
C. 5/6
30 people with soda + 45 people with lemonade = 75/90 people
simplifies to 5/6.
Step-by-step explanation:
4x² + 8x − 7 = 0
4x² + 8x = 7
x² + 2x = 7/4
x² + 2x + 1 = 11/4
(x + 1)² = 11/4
x + 1 = ±√(11/4)
x = -1 ± √(11/4)
This is about understanding GCMF.
<em><u>GCMF = x</u></em>
- GCMF is simply an abbreviation for greatest common factor.
- It is the highest factor that is common to 2 or more numbers or figures.
- We want to find the GCMF of x² + 2x.
- Let's list the factors of both;
Factors of x² = x, x
Factors of 2x = 2, x
- The factor common to both of them is x.
Thus,
GCMF = x

Answer:
Step-by-step explanation:
7x+9=2x+39
7x+9-9=2x+39-9
7x=2x+30
7x-2x=2x+30-2x
5x=30
5x/5=x
30/5=6
x=6
