x + 15 = 24
subtract 15 from both sides
x = 24 - 15 = 9
All you have to do is multiply both
Step-by-step explanation:
1 face area = length x width (aka length x length since cube)
therefore 1 side = ±√144 cm = 12 cm or - 12cm (rej as length > 0cm)
volume = length x width x height = 12 x 12 x 12 = 1728cm^3

First of all, we compute the points of interest, i.e. the points where the curve cuts the x axis: since the expression is already factored, we have
Which means that the roots are
Next, we can expand the function definition:
In this form, it is much easier to compute the derivative:
If we evaluate the derivative in the points of interest, we have
This means that we are looking for the equations of three lines, of which we know a point and the slope. The equation
is what we need. The three lines are:
This is the tangent at x = -2
This is the tangent at x = 0
This is the tangent at x = 1
Answer:
Step-by-step explanation:
Given is a steam and leaf plot.
This shows the age of customers who were interviewed in a survey by a store.
From the plot we can say that 10th digit is represented by the stem
For greater than 32, obviously 1,2 stem valus will not work.
For stem 3, we can leave 30 and 31 start with 2 in leaf and 3 n stem
We have 32, onwards 7 persons
Similarly for 4, we have 6, for 5 we have 5, for 6 we have 4 and for 7 we have 1
Total number of customers who have ages more than 32 years = 21
