Step-by-step explanation:
so first you look it up and if that dont work then u guess
Answer:
a(x)=2x^2+9x+4
Step-by-step explanation:
We have been given the length and width, as well as the formula to find the area:
Length: 2x + 1
Width: x + 4
A = l * w
A = (2x + 1)(x + 4)
2x^2 + 8x + x + 4
We can add like terms now:
2x^2 + 9x + 4
Our area is 2x^2 + 9x + 4
Our answer would be a(x)=2x^2+9x+4
Answer:
y=2/3x+8
Step-by-step explanation:
For this case we have a function of the form
Where:
We must find the value of the function when the variable x is -5.
Then, substituting,
We have that by sign law
