Answer: 6 triangles
Step-by-step explanation:
hope this helps :)
The new shower head dispenses 3 gallons of water per minute, as shown in the equation y = 3x.
So, 3 x 8 = 24.
Then, to find out how much he saves each day, you would find how much he used before,
11 x 8 = 88
Next we want to see how much Nathan saved, so we subtract the total,
88 - 24 = 64
Nathan saved 64 gallons.
First square both sides to get:
c + 22 = (c + 2)^2
or
c + 22 = c^2 + 4c + 4
Move the terms on the left side to the right side:
c^2 + 3c - 18 = 0
Factor to get:
(c + 6) * (c - 3) = 0.
The solutions are c = -6 and c = 3.
Check to see if these answers work by plugging them into the original equation:
c = -6:
sqrt (-6 + 22) ?= -6 + 2
But, -6 + 2 is a negative number, and you can't get a negative from a square root. So, -6 is extraneous.
c = 3:
sqrt (3 + 22) ?= 3 + 2
5 = 5. So, 3 works.
The answer is: B

Answer: who ever arrives at the answer x=0/3 =0 is correct
Step-by-step explanation:
Even though I need supporting details from the individual answers of Jane and Jill to pass my own judgment.
Given the expression
(2x²+x) +2(-x²+×)=0
Let's us open the bracket
2x²+x-2x²+2x=0
Collecting like terms
2x²-2x²+x+2x=0
3x=0
x=0/3
x=0
