Answer:
6(3√3-2)
Step-by-step explanation:
(√8/3 - √24 + √50/3) . √6
(√8/3 - 2√6 + 25√2/3) . √6
(2√2/3 - 2√6 + 25√2/3) . √6
(27√2/3 - 2√6) . √6
(27√12/3 - 12)
9√12-12
√12(9-√12)
2√3(9-2√3)
6(3√3-2)
Cost of Television = $1420
Cost of Television after store sale =$1022.40
Drop in price= 1420-1022.40= 397.60.
Price taken off = $ 397.60.
Percentage taken off= 
= 
Percent off = 28%.
Answer:
b.) 2
Explanation:
Parallel slopes have same slope.
Perpendicular slopes have negatively inverse slope.

Comparing it with slope intercept form, "y = mx + b" where m is slope.
Here parallel slope: -1/2
Perpendicular slope: -(-1/2)⁻¹ = 2
Answer:
Elimination
Step-by-step explanation:
The following system of equations can be easily solved by elimination as we can simply eliminate x-term.
Substitution will take a lot of time because you need to move to make either x-term or y-term as the subject then substitute in.
Graphing Method — You need to find the intercepts of both equations. You also have to convert into slope-intercept form which takes a lot of time.
Answer:
7.1
Step-by-step explanation:
A = s**2
50 = s**2
s = 50**(1/2) = 7.07 rounded = 7.1
