Definition :-
When many plain surfaces combine eachother yielding staright edges ,sharp vertices is called polyhedron .
#1
Yes
- It's cuboid or rectangular prism
#2
No
It has circular shapes ,no sharp edges
#3
No
- It has a sharp vertice but no staright edges .
#4
Yes
- It has flat base and sharp edges also staright edges
Hexgonal pyramid
The table would be y = 6x
Divide the Y values by the X values and they all equal 6, so you multiply the X value by 6 to get y.
Look at the dots on the graph ( 1,5) (2,10) (3,15) (4,20)
Divide the Y value by the X and they all equal 5, soy = 5x
Given:
Steven wrote this equation:
![4\times 18=418](https://tex.z-dn.net/?f=4%5Ctimes%2018%3D418)
To find:
The error in Steven's reasoning and then find the correct product.
Solution:
We have,
![4\times 18=418](https://tex.z-dn.net/?f=4%5Ctimes%2018%3D418)
This statement is incorrect because we cannot write product directly as Steven wrote.
We need to multiply the place values of each digit of first number with the place values of second number and then we need to add the resulted values.
![4\times 18=4\times (10+8)](https://tex.z-dn.net/?f=4%5Ctimes%2018%3D4%5Ctimes%20%2810%2B8%29)
![4\times 18=4\times 10+4\times 8](https://tex.z-dn.net/?f=4%5Ctimes%2018%3D4%5Ctimes%2010%2B4%5Ctimes%208)
![4\times 18=40+32](https://tex.z-dn.net/?f=4%5Ctimes%2018%3D40%2B32)
![4\times 18=72](https://tex.z-dn.net/?f=4%5Ctimes%2018%3D72)
Therefore, the correct product is 72.
C
Trinomial means three parts
A and C or trinomial's but the degree on a is at three and the degree of C is a one
Answer:
C = 8
Step-by-step explanation:
So to get C by itself, we need to add 12 to both sides of the equation, which is the opposite of subtracting:
C - 12 = -4
C - 12 + 12 = -4 + 12
C = 8
