Answer:
x=y[base side of isosceles triangle]
x²+y²=19²
x=√{19²/2)}
x=13.44
y=13.44
Answer:
12.2 gallons for $1.87, I would spend probably 2.87 for 24.4 gallons
Answer:
x+3= 2x when x = 3
3+3 = 2*3
6= 6
They are not equal when x is any other number rather than 3
The solution is x = 1 and x = -3
<em><u>Solution:</u></em>
Given that we have to solve the given equation by factoring
Given equation is:


Find a pair of integers whose product is c and and whose sum is b

Now find, a pair of integers whose sum is -2 and product is -3
The integers that satisfies this condition is -1 and 3
When we add - 1 and 3 we get 2
When multiply -1 and 3 we get -3
Thus the pair of integers are -1 and 3
Write the factored form using these integers.

The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0
Set the factors equal to 0

x = 1 and x = -3
Thus the solution is x = 1 and x = -3
