If we are trying to find x then it is 21
all you have to do is set them equal to each other
so (4x+3)=87
let me know if I need to explain more
There are two equal tables.
We need to add bases and multiply that by the height divided by two.
7+3=10•1=10
Now multiply that by two since there are two tables.
10•2=20
So, the tables area are 20 feet squared.

Answer:
y = 2x - 3
Step-by-step explanation:
We are given the slope, m = 2
Our standard formula of a line is y = mx + b, so we can substitute for the x and y values of the point (3, 3). If you did not know, the x-value and the y-value are both 3 because the point (3, 3) = (x, y).
So, our equation looks like this:
3 = (2)(3) + b
We can solve for b:
3 = 6 + b
b = -3
And now we have our equation of a line:
y = 2x - 3
To get the answer we have to substitute x=3 and add 6 to the result.
Lets do this
f(x)=7-2x
f(3)=7-2*3=7-6=1
f(3)+6=1+6=7 - its the result
