Okay. The question is m/9 - 17 = 21. First off, we will add 17 to both sides. -17 + 17 cancels out. 21 + 17 is 38. That leaves m/9 = 38. Multiply each side by 9 to isolate the m, because m is the numerator and 9 is the denominator. m/9 * 9/1 cancels out. 38 * 9 is 342. Let's check this. 342/9 is 38. 38 - 17 is 21. 21 = 21. There. x = 342.
91 * 8 = 91 * v
728 = 91 * v
v = 8

Answer:
i = 1000cm2
ii = 100000cm3
Step-by-step explanation:
for q i
surface area of base = l* b
= 50* 20
1000cm^2
for q 2
volume l*b*h
= 50*20*10
= 100000cm^3
hope it will be helpfull
