5 raised to the 4th power
Answer:
See below in bold.
Step-by-step explanation:
The formula is Tn = n(n + 1) / 2
The first triangular number is 1(1+1) / 2 = 2/2 = 1.
So the 15th = 15(15+1) / 2 = 120.
and the 19th = (19 * 20) / 2 = 190.
Answer:
A cross section perpendicular to the base would "cut" the prism through the height and width of the prism.
This would make a rectangle, with two sides the same length as the base ( 2 ft) and 2 sides the height of the prism ( 12 ft).
The answer would be:
A rectangle with two 12-ft sides and two 2-ft sides.
14+2x=4x: divide 2x on each side
14=2x: divide by 2
7=x
