(f∘g)(3) = f(g(3))
Find g(3) by substituting x=3 in g(x)
g(x)=x²-1
g(3)=3²-1
g(3)=9-1
g(3)=8
f*g(3) = f(g(3)) = f(8)
find f(8) by substituting x=8 in f(x):
f(x)=2x+3
f(8)=2(8)+3
f(8)=16+3
f(8)=19
So f∘g(3) = 19
Sorry I am wrong
If you are adding all the angles, then it equals 180 degrees.
If you are looking for the missing angle out of 360.. then it is 180
In order to find the perimeter, we need to have the length and the width. We are told that the area of the rectangle is 42. We will use that in the area formula, length times width, to solve for w. 42 = 7w so w = 6. The length is 7 and the width is 6. The perimeter formula for a rectangle is P = 2L + 2W. We have both the length and the width now, so we fill in accordingly. P = 2(7) + 2(6). And P=14+12. The perimeter then is 26 inches.
There are 1000 grams in a gram and 1000 times 10 is 10000 so yes 100 mg is less than a 10g
F(2) = 8
if x = 2 then you plug in 2 for x making the equation 3(2) + 2 which equals 8
