Miranda feeds her fish 12 milligrams of food every 3 days. About how many millagrams of food will she need to feed her fish for 32 days?

128 miligrams for 32 days

Step-by-step explanation:

To do this question, you first need to find out how much food she feeds per day so to do this, you do 12 mg/3 days and you get 4mg/day.

Then you multiply this number by 32.

4mg/day (32 days) = 128 mg

Procedure :

12 milligrams - 3 days

(3 divided by 12 = 4)

4 - day

4 x 32 = 128

Answer :

To feed her fish for 32 days, she will need 128 milligrams of fish food.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
