Okay so first you want to simplify the given equation (7x+3y)(7x-3y)
in order to do this you multiply the first number of the first equation (7x) with the first number of the second equation (7x) this gives you 49x^2
Now you want to multiply the second number of the first equation (3y) by the second number of the second equation (-3y) this gives you -9y^2
Its as easy as pie!
Answer:16
Step-by-step explanation:
Since she has 2 pizzas and she can get 8 silces from each it is 16 because 8x2=16
The dividing line will have to hit the points (0,2) and (3,0)
then you can test the point (0,0) which satisfies the inequality, so you will shade the side that has (0,0) on it, so it's the first picture.
Standard form is f(x)=ax^2+bx+c
order of power
f(x)=2x^2-11x+2
