Simplest radical form of an expression is the expression in radical so that there are no more square roots, cube roots, 4th roots, etc left to find, after rationalising the denominator ( if needed ).
2. Here the given expressions,
For rationalising the denominator multiply both numerator and denominator by √11,
3. given expression,
y - 6 = 4(1 - 4)
y - 6 = 4 - 16
y - 6 = -12
y = -12 + 6
y = -6
This is a horizontal line through the point (0, -6). See below.
Answer: 12.32%
Step-by-step explanation:
1. is the original long side and
is the original short side.
2. The area of the original rectangle is .
3. The rectangle is extended 4% on the long sides and 8% on the short sides. therefore, the new long side is:
4. And the new short side is:
5. The new area is:
6. The percentage of increase is calculated by substracting the new area and the original area:
7. The result is:
(0.1232)(100)=12.32%
