<span>x2 – 4x – 12 A) (x – 6)(x + 2)
x2 + 4x – 12 B) Prime
x2 – x – 12 C) (x – 4)(x + 3)
x2 – 7x – 12 D) (x – 2)(x + 6) i think this is the awnser:)</span>
The sum of the first n natural numbers and 0=
n*(n+1)/2
Total number = 30
1/5 of 30 = 1/5 x 30 = 6
The attached figures show the total number of filled
circles in five lines. Each line have “6” filled circles.
So 5 lines having 6 filled circles = 5 x 6 = 30
<span>Every line represents “1/5” of total amount “30”. Which
proved that 1/5 of 30 is equal to 6. </span>
Answer:
Hi! The correct answer is x= -7/2
Step-by-step explanation:
Solve the rational equation by combining expressions and isolating the variable x.
6y - 4(y - 1) +6
6y - 4y -4(-1) + 6
6y - 4y +4 + 6
2y + 10
