A right square pyramid is shown. The base has a side length, b, of 30 centimeters (cm). The height, h, is 10 cm. What is the length, in centimeters, of l?

Draw and label a triangle to model how to find the length of l.
What are the lengths of the legs? How do you know?

What is the length, in centimeters, of l? Use your model to help you find this value.

Step-by-step explanation:

Without the illustration, I assume that L is the slant height of a triangular face.

L = √(15^2 + 10^2) = 5√13 cm

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
