It is D because all the numbers range from 12 to 23, with no number being extremely low or high compared this range.
Answer:
Helen’s net is correct because she reorganized the solid as a triangular prism.
This is because the net has a rectangular base and 4 triangular sides.
Step-by-step explanation:
Rectangular SA one side+1 = 30 x 9 = 270 + 1s= 270 x 2 =540sq^2
Rectangular side one side +1 = 18 x 9 = 162 +1s = 162 x 2 = 324sq^2
2 x 2 triangular sides either end = 4/3 x 15 x 27.3 + 18 x 30.9 = 409.5 (x2) = 819sq^2
=864 + 360
Pyramid area = 1236.71sq^2
Volume = V=1620^3
Solution:
Given:

To get the product of the polynomial; we use the distributive property of multiplication.


Therefore, the product of the polynomials is;
First simplify the square roots.
√25 is 5 and √16 is 4
so the equation is 3x5 + 4x4
15+16
31
