Answer:
x = 2
Step-by-step explanation:
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
Answer:
95 square units
Step-by-step explanation:
Surface area of pyramid = 4(side area) + base
Solve for the base first.
Area of base = s*s = 5*5 = 25
Next solve for one of the sides.
Area of triangle = 1/2 b*h = 1/2 5*7 = 17.5
Plug these back into our original equation.
Surface area of pyramid = 4(side area) + base
Surface area of pyramid = 4(17.5) + 25
Surface area of pyramid = 70 + 25 = 95 square units
Answer:
x = 4.2
Step-by-step explanation:
14.1² + x² = 14.7²
198.81 + x² = 216.09
216.09 - 198.81 = 17.28
√17.28 = 4.15
x = 4.15
Round to nearest tenth
x = 4.2
