Answer:
The perimeter of triangle ABC is 146 units
Step-by-step explanation:
we know that
The segment AB, AC and BE are tangent to the circle G
so
The circle G is an inscribed circle
The point G is the incenter of the inscribed circle within the triangle
therefore
AE=AD
BF=BE
CD=CF
we have
AB=56 units
BE=16 units
CD=17 units
Find the value of AE
AE=AB-BE
substitute the given values
AE=56-16=40 units
Find the perimeter
The perimeter of triangle ABC is
P=2[AE+BE+CD]
substitute
P=2[40+16+17]=146 units

Answer:
f(g (x))= 32x-18
g (f (x))=32x2+42
Step-by-step explanation:
f (g (x))= 4 (8x-6)+6
32x-24-6
32x-18
g (f (x))= 8(4x2+6)-6
32x2+48-6
32x2+42
Well if you divide 7 divided by 12 you get 0.583 which you can round however you wish but I am not sure if that’s what you mean
Answer:
b AND e
Step-by-step explanation:
To find the mean: You have to add them all together, then divide them by how many numbers there are.
So: 23+25+32+35+36+25+27 = 203
How many numbers did we add up? 7.
203 ÷ 7 = 32.85714 (That is the mean rounded up to the nearest hundredth thousandth).
