t=D/r
Divide r by both sides to get t by itself.
Longitud = L Ancho = A
2A + 2L = 54
L = 2A Sustituir este valor por L en la primera ecuación:
2A + 2(2A) = 54
2A + 4A = 54
6A = 54
A = 9
También porque L = 2A,
L = 2(9) = 18
Answer:
12/28
Step-by-step explanation:
3 x 4 = 12
7 x 4 = 28
1 17/20
the 1 is ur whole number....it stays ur whole number
17/20 = 0.85
so we have 1.85.....to turn it into a percent, move the decimal 2 spaces to the right = 185%
Answer:
a) for all values of x that are in the domains of f and g.
b) for all values of x that are in the domains of f and g.
c) for all values of x that are in the domains of f and g with g(x)≠0
Step-by-step explanation:
a) By definition (f+g)(x)=f(x)+g(x). Then x must be in the domain of f and g.
b) By definition (fg)(x)=f(x)g(x). Then x must be in the domain of f and g.
c) By definition (f/g)(x)=f(x)/g(x). Then x must be in the domain of f and g and g(x) must be different of 0.
