Explain how you could calculate the surface area of a square pyramid.

Solve the system of equations using row operations. Write your answer in the form (x, y). {2x+3y=-2 {3x-y=19

Solve for x: 2/5 + 3/5x = x+5/10 the answers are: x=-3 x=2 x=-3 and x=2 no solution

Which expression is equivalent to 9 (15)

The mean (average) height of 4 girls is 152 cm. Melissa joins the group and the mean height of the group of the 5 girls is now 151.6 cm. What is Melissa's height?

Use substitution to solve the linear system of equations. x = 4 -y = 1/2x (4, - 2) (-2, 4) (4, 2) (2, - 4)

What is (24-6) + 19:2

Now 3 equivalent ratios to 5 over 2 and 4 over 7

Is it always, sometimes, or never true that a scatter plot that shows a positive association suggests that the relationship is proportional?

Two triangular prisms are similar. The perimeter of each face of one prism is double the perimeter of the corresponding face of the other prism. How are the surface areas of the figures related? A) The surface areas are the same.
