1) Answer: The part of the quadratic formula tells us whether the quadratic equation can be solved by factoring is b^2-4ac
2) 4x^2+6x+2=0
ax^2+bx+c=0; a=4, b=6, c=2
b^2-4ac=(6)^2-4(4)(2)=36-32
b^2-4ac=4
Answer: b^2-4ac=4
Answer:
t=16
Step-by-step explanation:
you have to change the numbers to get just the variable.
we start from -3.
5=t/2-3
8=t/2
(we multiply by 2 instead of dividing)
8×2=16
t=16

To find the percent of the total payment that the down payment is we have to you use the following equation:

Lets start plugging things into the equation.
The part is equal to the down payment and the whole is the total cost of the studio apartment.
Let's do this for the first question

So we see that 24,000 is 20% of the total purchase price!
Let's do this for the next question:

48,000 is 40% of the 120,000 total cost!
