I think it’s one half 1/2
Answer:
A
Step-by-step explanation:
x² + 10x + 24 = 0
Here, a = 1, b = 10, c = 24. Factoring using the AC method:
ac = 1×24 = 24
Factors of 24 that add up to 10 are +4 and +6.
Therefore:
(x + 4) (x + 6) = 0
x + 4 = 0, x + 6 = 0
x = -4, x = -6
The roots are -4 and -6. Added together:
-4 + -6 = -10
Answer A.
I hope this helps you
5x^2+30x+65=0
5 (x^2+6x+13)=0
x^2+6x+13=0
a=1 b=6 c=13
disctirminant=b^-4ac
disctirminant=6^2-4.1.13
disctirminant=36-52
disctirminant= -16
x1= -6+square root of -16/2.1
x1= -6+4i/2=2i-3
x2= -6- square root of -16/2.1
x2= -6-4i/2= -3-2i
Answer:
84.8
Step-by-step explanation:
Begin by finding the total area of the circle. You have been given the radius.
A = πr²
A = π(6)²
A = 36π
A = 113
If there is only 3/4 of the circle, then multiply the entire area by 3/4 to find the final answer.
113 x 3/4 = 84.8
Answer:
Step-by-step explanation:
Well the square root of 16 can be simplified to 4, which can be represented as a fraction: 4/1, so it's not irrational, but rather rational.
Whole numbers are similar to integers, and natural numbers, the only difference is integers includes all real numbers, which do not have a decimal value. So this includes negative numbers, zero, and positive numbers.
Whole numbers include all real numbers, which do not have a decimal value, and are greater than or equal to zero, or in other words, not negative.
Natural numbers include all real numbers, which do not have a decimal value, and are greater than zero, or in other words, positive numbers.
So this number is a integer, and rational number. (since the negative number in front of the radical)
