Answer:
No, The answer should be 240
Step-by-step explanation:
- The first step to finding the Surface Area was done well and was right but you got confused when trying to add the area of each shape
- There is 3 Rectangles and 2 Traingles.
- Let's start with the area of the triangles. 1/2bh is the formula for finding area of Traingles. 1/2(4)(6) = 12. We have two Traingles so that would be 24.
- Now we have three rectangles with different lengths we need to calculate.
- Rectangle 1 = 12 * 8 = 96
- Rectangle 2 = 12 * 6 = 72
- Rectangle 3 = 12* 4 = 48
- 24+96+72+48 = 240.
- So, the surface area of the rectangular prisim is 240
Answer: 23
Explanation:
Second quartile is another word for the median
15a - 6
You have to use the distributive property.
Answer:
y = 3x + 1
Step-by-step explanation:
Consider the differences between consecutive terms of y
1 → 4 → + 3
4 → 7 → + 3
7 → 10 → + 3
10 → 13 → + 3
13 → 16 → + 3
The differences are constant, the constant is the multiplier, that is
y = 3x
Given the point (0, 1 ) , thus add 1 to the 3x term , hence
y = 3x + 1 ← equation relating x and y
N = 288
First, both 36 sqrt 2 and 24 sqrt 2 have the common sqrt 2, which means you can directly subtract them.
36 sqrt 2 - 24 sqrt 2 = 12 sqrt 2
12 is outside of the square root means it was a perfect square, thus 12*12 = 144.
There's still a 2 left in the sqrt, and 144 * 2 = 288.
