Answer:
Rationalize the denominator by multiplying by the conjugate of (1 + √3), namely (1 - √3). this gives us
(1 - √3) / (1 - 3) or (1 - √3) / -2, which can be rewritten as
(-1 + √3)/2, the last answer choice.
The two ratios in the tables shown which have a common denominator you could use to compare is; 3/12 and 4/12
<h3>Ratio</h3>
Machael's ratio:
lemons to water = 1:4
Equivalent ratio
= 3 : 12
= 4 : 16
Sondra's ratio:
lemons to water = 2 : 6
Equivalent ratio
= 4 : 12
= 6 : 18
Therefore, the two ratios in the tables shown which have a common denominator you could use to compare is; StartFraction 3 Over 12 EndFraction and StartFraction 4 Over 12 EndFraction

Step-by-step explanation:
7.4÷4= 1.85
1 jar weighs 1.85 pounds
1.85×24= 44.4 pounds
another way:
7.4x6= 44.4pounds
I believe what we are looking for is area. If so the formula for area of a rectangle is area equals width times length
A=wl
So:
9*13=117
The area would be 117, the amount of wall space needed is 117.
Hope this helps:)
Answer:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values.
