Required
Explain his error
The question says 5/8
Instead, Alejandro's working shows 8/5.
This working is done in an incorrect order and the correct solution is:
Let
Solve the fraction
Multiply by 100%
<em>Hence, option (a) is correct.</em>
With polynomials the degree is the highest power x or whatever the variable is raised to. In this case, the degree is 3 since the highest power x is raised to is x^3
C = 9 m the perimeter is all the sides added together you have 9 +8 that is 17 add another 9 and that equals 26 which is the perimeter.<span />
How much part can sally paint in an hour ?
a ÷ 7 = a/7
And what about Steve ?
a ÷ 9 = a/9
Where, a is the total area of the room.
So, let the time taken by both of them to paint the room together be 't'
So,
t(a/7 + a/9) = a
t(9a/63 + 7a/63) = a
t(16a/63) = a
t = 63/16 ≈ 4 hr
