Answer:
i cant see the picture
Step-by-step explanation:
21/9 + 74/9 = (21 + 74)/9 = 95/9 = 10 5/9
The volume of a pyramid is computed by multiplying the base length, base width, and pyramid height and divide it by 3.
Volume = (base length x base width x height)/3
since this is a square, base length and width are equal.
w=l=10cm
h=12cm
Substituting the given values in the formula, we will get the volume of the pyramid
Volume=(10cmx10cmx12cm)/3
Volume= 400cm^3
The relationship between y and x is y = 5x + 15.

Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are the variables, m is the rate of change (slope) and b is the initial value of y (y intercept).
From the table, using point (5, 40) and (25, 140):

The relationship between y and x is y = 5x + 15.
