Answer:
AFM = 140
LFM = 70
Step-by-step explanation:
Here, we are to calculate LFM and AFM
Since AFM was bisected, then LFM + AFL is AFM
and also AFL = LFM
Thus;
11x + 4 = 12x -2
12x-11x = 4 + 2
x = 6
AFM = AFL + LFM = 11x + 4 + 12x-2 = 23x + 2
Substitute x = 6
AFM = 23(6) + 2 = 140
LFM = 11x + 4 = 11(6) + 4 = 66 + 4 = 70
Steps:
1. Multiply the first line by 3 and the second by 2
3(3x + 2y= 4)
2(8x -3y=-6)
2. New lines are
9x + 6y= 12
16x + -6y=-12
3. Now add/subtract them
25x + 0= 0
25x=0
4. Divide by 25
X=0
5. To find y, substitute the 0 in the x in one of the equations
9x + 6y= 12
9(0) + 6y= 12
6y= 12
6. Divide by 6, your Y=2
7. X=0, Y=2
Answer:
108cm
(B)
Step-by-step explanation:
Find the area of the triangle first.
6 * 4 = 24/2 = 12
Multiply by the width.
12 * 9 = 108
