Answer:
78 cm should be the correct answer
Step-by-step explanation:
we can use synthetic division
and then we can find quotient
we can see in the image
we will get
![quotient=2x+7](https://tex.z-dn.net/?f=%20quotient%3D2x%2B7%20)
![remainder=0](https://tex.z-dn.net/?f=%20remainder%3D0%20)
![(2x^2+9x+7)=(x+1)(2x+7)](https://tex.z-dn.net/?f=%20%282x%5E2%2B9x%2B7%29%3D%28x%2B1%29%282x%2B7%29%20)
so, we get
.............Answer

Of course not.
If the line rises higher as it goes from left to right,
then its slope ( 'm' ) is positive.
If it sinks lower as it goes from left to right,
then its slope ( 'm' ) is negative.
bearing in mind that a solution to a system of equations is where their graph intersect or meets, Check the picture below.
