Answer:
6
Step-by-step explanation:
-15+6 means it goes minus basically its 15-6(-15+6)=-9
r=-6
You have to use distributive property and multiply parentheses
1.60 *3 is 4.80-1.95=2. 85 a large container is $2.85
Start with an equation.
Nine less... so -9
3 times a number = 3x
Greater than 40 is >40
So put together is 3x-9>40
When solving I imaging the greater than sign as an equal sign. Less confusing.
3x-9=40
3x=49
x>49/3
X^2 + 12x + n
x^2 + 12x + (12/2)^2
x^2 + 12x + 6^2
n = 36
(x + 6)^2 will give you a perfect square.
