Answer:
±2 sqrt(3) =x
Step-by-step explanation:
12 - x^2 = 0
Add x^2 to each side
12 - x^2 + x^2 = x^2
12 = x^2
Take the square root of each side
±sqrt(12) = sqrt(x^2)
±sqrt(4*3) = sqrt(x^2)
±sqrt(4) sqrt(3) = x
±2 sqrt(3) =x
Answer:
Step-by-step explanation:
3x^2 + 5x + 25 when x = 3
= 3(3)^2 + 5(3) + 25
= 3(9) + 15 + 25
= 27 +15 + 25
= 67
D=(b^2)-(4)(a)(c)
36-(4)(-2)(13)= 139
Answer:
1/6
Step-by-step explanation:
if there are 6 sides on a dice and the space is 3 moves away, then you have a 1/6 chance of rolling a 3 and landing on it.
Answer:
I=Prt
Step-by-step explanation:
The simple interest formula is given as;
I = Prt
where I is the simple interest
p is the principal
r is the percentage rate
t is the duration
Simple interest accrues on the principal of either a loan or an investment. This amount is payable after a duration of time.
Principal is the amount borrowed or invested in a business
Rate is the percentage commission to be paid on the amount borrowed
Time is the duration of the borrowing.
