Answer:
Step-by-step explanation:
You have to use the discriminant for this. If the quadratic is 
, then
a = -4, b = -3, and c = 7. The formula for finding the discriminant is
which comes from the quadratic formula, but without the square root sign. Filling in:
which simplifies down to
D = 9 + 112 so
D = 121. This is a perfect square, so the solutions will be 2 real. Just so you know, you will NEVER have a solution like the one offered in the third choice down. If you have one imaginary root, you will ALWAYS have a second by the conjugate rule.
Answer:
I'm pretty sure it's 1 cup of water
You need 2 cups of pancake mix more than water so if you have 3 cups of pancake mix then you'd need 1 cup of water.
6 cups of mix = 4 cups of water
the cups of the mix is are 2 more cups than the water
3 cups of mix = 1 cup of water
I hope that helps and good luck! :)

<span>C. E(n)=5n+42
5 times the number of people + 7 times 6
</span>
3x - x + 8 + 5x - 2 = 10
combine like terms on the left, then add or subtract as asked
(3x - x + 5x) + (8 - 2) = 10
7x + 6 = 10
subtract 6 from both sides
7x = 4
divide both sides by 7
x = 4/7
Hope this helps! :)
