Answer:
(E)A trapezoid
Step-by-step explanation:
Given the shape which is a rectangular based pyramid.
A cross-section is cut but it does not pass through the top vertex of the pyramid.
- The shape formed will have two parallel unequal sides (the base and the top)
- However, the other two sides will be slant.
Therefore, the shape which describes the cross-section will be a trapezoid.
Hi there!
The roots of a function are when f(x) = 0, so:
0 = x² + 9x - 36
Find two numbers that multiply to -36 and add up to 9.
We get the numbers 12 and -3, so:
0 = (x + 12)(x - 3)
Set each equal to 0 to find the x value:
0 = x + 12
x = -12
0 = x - 3
x = 3
Step-by-step explanation:
They are all polygons with four sides.
The sum of the measures of their interior angles is 360°.
