This problem is a difference of squares. So to solve this you want to factor it out so you get two numbers that multiple to -9 and add to 0. That would be -3 and 3
f(x)=(x-3)(x+3)
So your solution when you set f(x) to 0 would be -3 and 3.
Answer:
The cross section of a pyramid that is perpendicular to the base will be a triangle.
Step-by-step explanation:
Answer:
Product before increasing: 4200
x after increase: 60 * 105% = 63
y after increase: 70 * 110% = 77
Product after increasing: 4851
Percentage increase in the product: 4851 / 4200 * 100 = 115.5%
Remember, you can do anything to an equation as long as you do it to both sides
we hates fractions
times both sides by 3
(we could have added 1/3b to both sides but I'm lazy)
4b+6=12-b
add b to both sides
5b+6=12
minus 6 both sides
5b=6
divide both sides by 5
