Answer:
Ok ill help
Step-by-step explanation:
Area=lw
l=2w
aera=2l^2
72=area
72=2l^2
divide both sides by 2
36=l^2
sqrt both sides
6=l
length=6 units
Answer:
x > -3

Step-by-step explanation:
Domain: input values (x-values)
Monotonic increasing: always increasing.
A function is increasing when its graph rises from left to right.
The graph of a quadratic function is a parabola. If the leading term is positive, the parabola opens upwards. The domain over which the function is increasing for a parabola that opens upwards is values greater than the x-value of the vertex.
<u>Vertex</u>
Standard form of quadratic equation: 

Given function:

Therefore, x-value of function's vertex:

<u>Final Solution</u>
The function is increasing when x > -3

<h3>There are 25 servings</h3>
<em><u>Solution:</u></em>
Given that,
<em><u>The label on a 1-kilogram can of mixed nuts states that a serving size is 40 grams</u></em>
From given,
Total = 1 kg
We know that,
1 kg = 1000 grams
Serving size = 40 grams
<em><u>How many servings are there in the can?</u></em>

Thus there are 25 servings
