Step-by-step explanation:
The line of best fit is y = 2.599x + 105.08. At x = 20, the estimated height is y = 157.06. The actual height is 160 cm, so the residual is:
160 cm − 157.06 cm = 2.94 cm

<u>Given:</u>
(2+√3)+(4-√3)
<u>To Find:</u>
Evaluate the expression
<u>Solution:</u>
<u>⇨</u><u>Step 1:</u>
Remove the parentheses
(2+√3)+(4-√3)
When there is + or no sign in front of an expression in parentheses, the expression remains the same
= 2 + √3+ 4-√3
<u>⇨</u><u>Step 2:</u>
Cancel the opposite terms √3 and -√3
"Two numbers are opposites if they have the same absolute value but different signs"
= 2 + 4
<u>⇨</u><u>Step 3:</u>
Add the numbers
= 6
<u>Hence (2+√3)+(4-√3) = 6</u><u>.</u>
