hi please show all steps and explain thank you

Dimensional Analysis 8. Use dimensional analysis to determine whether the formula x = vt-Zat' is plausible if x has units of m, v has units of m/sec, t has units of sec, and a has units of m/sec'. 9. A certain formula is given by v= xx'a't'. The variables have the same units as those in the previous question. What must be the value of n if the formula is to be dimensionally correct? 10. A certain quantity p is represented by the formula p=qr(.s'--t)2 . If p has units of m3] sec, 4 has units of sec, and r has units of m, use dimensional analysis to determine the units of s and r
