Answer:
Here u go bucko
Step-by-step explanation:
A quadratic equation ax^2+bx+c has no equal roots when discriminate that is when b^2-4ac is less than 0.
I'm assuming 3 because 6 simplified is 3 and the rectangles are similar
I'm assuming this is a yearly interest.
2500*.04=100
7500*.05=375
so that would be $475 earned from interest
Answer:
x = ±1/2
Step-by-step explanation:
x^2-1/4=0
Add 1/4 to each side
x^2 -1/4+1/4 = 0+1/4
x^2 = 1/4
Take the square root of each side
sqrt(x^2) = sqrt(1/4)
x = ±1/2
To get 3 5/6 - 4 5/12, you would have to get the denominators even. So 12 is the lowest, so lets use that.
3 5/6 - 4 5/12
3 10/12 - 4 5/12
3-4= -1
10-5= 5
Now, you have a -1 and a + 5/12, to do this you have to turn -1 into -12/12
-12/12 + 5/12 = -7/12
Your answer is -7/12
Hope this helped!
