I(interest)=P(princple)R(rate)T(time)
I=420*.07*1=$29.4
A is correct.
Peace.
For number 16
2x+6+x=180
3x+6=180
3x=180-6
3x=174
x=58
2(58)+6 =122
Linear pairs are 180 degree angles
Angle 1 = 58
Angle 2 = 122
<span>If it is a right prism, then the cross-section area will be considered a rectangle. Each lateral face will be perpendicular to the base, and if we cut the plane it will be perpendicular to the bases and the resulting angles of the cross-section would all be simply right angles.
Hence,
The best Answer would be third Option: A RECTANGLE.

Answer:
18 inches
Step-by-step explanation:
Volume of a pyramid is:
V = ⅓ Ah
where A is the area of the base, and h is the height of the pyramid.
The base is a rectangle. Area of a rectangle is width times length, so:
V = ⅓ wlh
Plugging in values and solving:
1512 = ⅓ w (21) (12)
w = 18
The width of the base is 18 inches.
