12. solve the following expressions:
i. 10(x - 2) – 4(x +1) + 3(x + 6) = 0
ii. 3(x - 1) + 4(2x +1) = 23.
iii. 2{(x + 1) + (x + 2)} = {(x + 3) + (x +4)}
iv. x+4/2+x-3/3=10
v. x-1/4+x+1/3=10
vi.7x/8+3/8=14
answer fast

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

the bolded word " farsighted" could be replaced with visionary.

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
