Fisrt is solve the distance of the segments using distance
formula
Distance =sqroot[(x2−x1)^2+(y2−y1)^2]
So ditance of RS = 5
ST = 8.49
TR =6.08
The using herons formula
Area = sqrt ( s ( s-a) ( s-b) ( s-c) )
Where s s = 1/2 ( a + b + c )
And a, b , c are length of the sides
S = 9.785
Area = 14.99
Answer:
The girl had 24 candies in her bag.
Step-by-step explanation:
Since, regarding the girl's candies, 4 of them were blue, 1/6 of them were grape, 1/4 of them were watermelon, 1/3 of them were cherry and 1/12 of them were sour apple, to determine how many candies were in her bag, the following mathematical calculation should be performed:
1/6 + 1/4 + 1/3 + 1/12 = X
2/12 + 3/12 + 4/12 + 1/12 = X
10/12 = X
12/12 - 10/12 = 2/12
2/12 = 4
1/12 = 2
2 x 12 = 24
Thus, the girl had 24 candies in her bag.
Answer:
2(x+3) (x+1)
Step-by-step explanation:
2x² + 8x + 6
Splitting the middle term (8x)..
2x² + 6x + 2x + 6 =0
x (2x + 6) + 1 (2x + 6)
(2x + 6) (x + 1)
2(x + 3) (x + 1)
Hence, option C. is the correct answer.
Multiply equation B by 2.
