60
D>0, there are 2 distinct real roots
Explanation:
3x2+6x−2=0
a=3,b=6,c=−2
The formula for discriminant is b2−4acSubstitute the given values.
b2−4ac
(6)2−4(3)(−2)
=60
therefore, D>0, there are 2 distinct real roots
Answer:
6/10
Step-by-step explanation:
Simplify 15/25 by dividing by 5/5
15/25 ÷ 5/5 = 3/5
Multiply 3/5 by 2/2 to convert to tenths

Answer:
As a fraction: 39/4 or 9 3/4
As a decimal: 9.75
As a percentage: uhhhhh- 75% of the colors.
As an integer: 10
Step-by-step explanation:
Multiplying fractions, you get 39/4 or 9 3/14
Pull out your calculator(or divide on paper), to get 9.75
Round that to 10.
3/4 = 75%
Hope this helps!
Answer:
17/12 or 1 and 5/12.
Step-by-step explanation:
3/4 and 2/3 needs to have the same denomenator. So, what number does both 4 and 3 go into? 12. So, 4x3=12, so we multiply the numerator by 3 too, to get 9 --> 9/12. Then, we see that 4x3=12 for 3 too so we multiply 2 by 4 which gets us 8 --> 8/12. So, now we add 9/12 + 8/12 to get 17/12, which then we make into a mixed number to get 1 and 5/12.
Answer:
Let x = the number
"Fifteen more than" means addition
"Three times a number" is multiplication
"three less than" is subtraction, as is the term difference
Putting it all together, we have
7 - (15 + 3x) = (9 - 5x) - 3
-8 + 3x = 6 - 5x
-8 = 6 - 8x
-14 = -8x
14/8 = 7/4 = x
