The complete question in the attached figure
we know that
[<span>amount of fabric]=8*[area of lateral triangle side]
area of lateral triangle side=(1/2)*4*5----> 10 ft</span>²
so
[amount of fabric]=8*[10]----> 80 ft²
the answer is80 ft²
Well i think is a) <span>m3

(2b+5)(3a-4)
Answer:
20
Step-by-step explanation:
You need to create two equations for each company and then set them equal to each other. The keywords base fee means you will pay this amount regardless, so this amount stays constant and it will be the constant in the equation. The other keyword is per. Per will link the variable with the coefficient.
The first equation for company M:
y = 12x + 60
The second equation for company N:
y = 9x + 120
Set the equations equal to each other.
9x + 120 = 12x + 60
Solve for x. I am going to subtract 9x from both sides first.
9x - 9x + 120 = 12x -9x +60
120 = 3x +60
Now, I will subtract 60 from both sides.
120 - 60 = 3x + 60 - 60
60 = 3x
Finally, I will divide both sides by 3
60/3 = 3x/3
x = 20
20 is how many guests it will take for the total cost to be the same.
