Answer:
w > -14
Step-by-step explanation:
Divide both sides by -6.
-6w/-6 = w
84/-6 = 14
Since it's an equality, if the coefficient of the variable is negative, when you divide the sign flips to the opposite.
Answer:
f(5) = 3200
Step-by-step explanation:
Using the recursive formula to generate the terms, that is
f(2) = 2 × f(1) = 2 × 200 = 400
f(3) = 2 × f(2) = 2 × 400 = 800
f(4) = 2 × f(3) = 2 × 800 = 1600
f(5) = 2 × f(4) = 2 × 1600 = 3200
So if 360 is increased by 25%, you would end up with 450 (360 x 1.25), than if the result, 450 is decreased by 50% ( 450 x .50 = 225) (450 - 225 = 225) you would end up with 225.
Answer: The first option.
Step-by-step explanation:
1. The formula for calculate the perimeter is:
P=2l+2w
Where l is the lenght and w is the width.
2. The first perimeter is:
3. If you multiply the dimension by a scale of factor of 2, is the same as write the following expression:
Where 
is the first perimeter.
4. Then:
extraneous root is a solution o an equation that seems to be right but when we check it (by substituting it into the original equation) it turns out not to be right
