Which expression represents a perfect square monomial and it’s square root? check all that apply
[]121; 11
[]4x2; 2x
[]9x2-1; 3x-1
[]25x; 5x
[]49x4; 7x2

i think just 121; 11

Step-by-step explanation:

you just times the number by itself ex; 11×11= 121

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
