answer is either A or D
I hope this help. but I'm not really sure.
We have the expression:

And want to evaluate in y=5, this means we have to replace y in the expression for 5 and calculate the value of the expression, so:

The expression is 30 when y=5.
Answer:

Step-by-step explanation:
Here, we add up two polynomials shown.
The polynomials are:
![[-m^2 + 6]+[-4m^2 +7m + 2]](https://tex.z-dn.net/?f=%5B-m%5E2%20%2B%206%5D%2B%5B-4m%5E2%20%2B7m%20%2B%202%5D)
In order to add up the 2 polynomials shown, we have to see the "like terms" and add them up.
We add up the "
" terms and the constant (number) terms. There is one term with "m", so we leave it like that. Let's add up. Shown below:\
![[-m^2 + 6]+[-4m^2 +7m + 2]\\=-m^2-4m^2+6+2+7m\\=-5m^2+7m+8](https://tex.z-dn.net/?f=%5B-m%5E2%20%2B%206%5D%2B%5B-4m%5E2%20%2B7m%20%2B%202%5D%5C%5C%3D-m%5E2-4m%5E2%2B6%2B2%2B7m%5C%5C%3D-5m%5E2%2B7m%2B8)
This is the sum of the 2 polynomials shown: 
We know that
area of the tent=length*breath
length=240 cm---convert to m---> 240/100----> 2.40 m
breath=170 cm----convert to m---> 170/100----> 1.70 m
find the area
area=2.40*1.70-----> area=4.08 m²
therefore
the answer is
<span>the friend's statement is incorrect the area is 4.08 m</span>²
Answer:
1) y = 3x+5
2) y = 
3) y = -x + 0
4) y = 
5) y = 
Step-by-step explanation:
y = mx+b
In slope-intercept form, these are important to know:
- y and x should stay as variables
- m = slope of the line
- b = y intercept
Using the facts above⬆, we can solve these problems
Remember: Substitute m and b using the given information
1) y = 3x+5
2) y = 
3) y = -x + 0
4) y = 
5) y = 
Hope this helps :)
Have a great day!
