an egyptian pyramid has a square base and four triangular faces. use clay or play-
doh to make a pyramid model. if you make different "plane cuts" through all 4 of
the triangles -- without cutting through the square -- which different shapes will the
cuts make? a plane cut is kind of like a cheese cutter -- it will be straight, not
curved.

Step-by-step explanation:

s=20

Step-by-step explanation:

First, plug in s to the equation.

4(t+5) + 2t =110

Then, distribute. That means multiply 4 to the variable and number inside the parentheses.

4t + 20 +2t = 110

Now, add like terms. The two numbers, 4t and 2t can be combined because they have the same variable.

6t + 20 = 110

Subtract 20 from 110 to isolate the variable.

6t = 90

Now, divide 90 by 6 to further isolate the variable.

t = 15

Now we have to find s. To find s, plug t = 15 into the equation.

s = 15 + 5

Lastly, add the two numbers to find s.

s = 20
