Answer:
y should be 90 degrees not sure about x
Answer:
D
Step-by-step explanation:
3x * 5x = 15x^2
3x * -3 = -9x
4*5x = 20x
4 *-3 = 12
so 15x^2 +(20x -9x) -12 or 15x^2 +11x -12

Complete Question
A right rectangular prism with dimensions 1 5/8 inches by 1 1/2 inches by 1 3/8 inches is made up of small cubes with side lengths of 1/8 inch. How many 1/8 inch cubes make up the right rectangular prism?
a) 429
b) 858
c) 1287
d) 1716
Answer:
d) 1716 cubes
Step-by-step explanation:
Step 1
Find the volume of the rectangular the rectangular prism
Volume = Length × Width × Height
Length = 1 5/8 inches
Width = 1 1/2 inches
Height = 1 3/8 inches
Hence, Volume = 1 5/8 inches × 1 1/2 inches × 1 3/8 inches
= 13/8 inches × 3/2 inches × 11/8 inches
= 429/128 cubic inches
Step 2
We find the volume of 1 cube
Volume = (side length)³
= (1/8 Inches)³
= 1/8 × 1/8 × 1/8
=1/512 cubic inches
From the above question
The number of 1/8 inch cubes make up the right rectangular prism is calculated as:
= Volume of right rectangular prism ÷ Volume of 1 cube
(429/128)cubic inches ÷ (1/512) cubic inches
= 429/128 × 512/1
= 429 × 4
= 1716 cubes
Therefore, the number of cubes in the rectangular prism is 1716 cubes.
29 is the median
If you just count all then the half number will be the 3rd 29
