Which of the following statements follows from (x - 3)2 = 7?
x2 + 9 = 7
x - 3 = ±
x - 3 = ±49

Option B is correct

Step-by-step explanation:

Given the equation:

taking square root both sides we have;

Using exponent rules:

then;

Therefore, the following statements follows from is,

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
