9x^3-39x^2-38x+40=(3x-2)(3x+4)(x-5) by synthetic division
Thus roots are -4/3, 2/3, 5
The answer is 6x
You have to add 12 and 3 which is 15 then you have to do 15 minus 9 then it is 6 then you will put the x there because it had 2 x and 1y so 6x is the answer
So break it down to decimals, if we know that 1/4 is 0.25 then we can work off of the left numberstart at the lowest possible, 1/51/5=0.2in this case 1/4 is larger than 1/5 so we go 2/5>1/42/5=0.4 which is larger than 0.25So 2 would be the lowest whole number to complete the comparison
2/5>1/4
Answer:
172.5
Step-by-step explanation:
mean of men=sum/no of men
177=sum/30
sum=177*30
= 5310
mean of women=sum/no of women
164=sum/16
sum=164*16
= 2624
mean height= (5310+2624)/30+16
=7934/46
=172.5
