6(y+3) = 72
6y + 18 = 72
6y = 72 - 18
6y = 54
y = 54/6
y = 9
Answer:
2(4x-3)
Step-by-step explanation:
Answer:
the fraction of surface that is not covered is 11/36
Step-by-step explanation:
To do this we first have to calculate the two surfaces
s = π * r^2
π = 3.14
r = d/2
d1 = 20
d2 = 24
r1 = 20/2
r1 = 10
r2 = 24/2
r2 = 12
s1 = π * r1^2
s1 = 3.14 * 10^2
s1 = 3.14 * 100
s1 = 314
s2 = π * r2^2
s2 = 3.14 * 12^2
s2 = 3.14 * 144
s2 = 452.16
to know the part that is not covered we simply do the s1 over the s2 and we subtract that from 1
s1 / s2 =
314 / 452.16 =
25/36
1 we subtract this
1 - 25/36 = 11/36
the fraction of surface that is not covered is 11/36
Answer:
The domain of function( f+ g)(x) ( (-∞,∞))
Step-by-step explanation:
Given ( f + g)x = f(x) +g(x)
The domain of function (f + g)(x) is (-∞,∞)
<em>Example:-</em>
<em>f(x) = 2 x² + 3x and g(x) = 4x² +3</em>
<em>(f + g)(x) = f(x) +g(x)</em>
<em> = 2 x² + 3x + 4 x² + 3</em>
<em> = 6x ² + 3 x + 3</em>
<em>The domain of (f + g) (x) is ( -∞,∞))</em>
