For the first one you just add the all the d together 5d+9d=14d and the c stays at 4 because there are no other c terms so it's 14d+4c
second expand by timesing 2*m=2m 2*5=10 2m+10+3=2m+13
This is cross multipication. Multiply 117 times 36 together for that you would use a calculator. You get 4221. Next step is to multiply x and 12 together that would be 12x.
4221= 12x
Divide by 12 on both sides:
x= 351
351 is # of trouts in the lake .
