Seventy four because 6*3 is 18 and 7*8 is 56, add them to get 74
Step-by-step explanation:
You've got the concept correct, but be careful with your parentheses. You should write it 3/(2n). Otherwise it looks like three halves n.

3x*3x=9x^2
3x*-8=-24x
6*3x=18x
6*-8=-48
9x^2-24x+18x-48
9x^2-6x-48
Answer:
✔️Ratio of weight to mass in simplest form: 49/5 or 49 : 5
✔️x = 110
Step-by-step explanation:
Since the ratio of weight to mass is constant, therefore we can use any pair of values from the table to find the ratio that represents the table. Let's pick the first row:
(20, 196)
Ratio of weight to mass = 196 : 20
= 196/20
= 49/5
Or 49 : 5
✔️Let's use this ratio/proportion to find x in the table
Ratio of weight to mass = 49:5
Thus:
1078/x = 49/5
Cross multiply
x*49 = 1078*5
49x = 5,390
x = 5,390/49
x = 110
