Answer:
Step-by-step explanation:
GHIJK ~ QPTSR means that: pentagon GHIJK is similar to pentagon QPTSR
With this information, we see that we will have to use proportions to find PT
GH ~ QP =
HI ~ PT =
IJ ~ TS =
JK ~ SR =
KG ~ RQ =
Another way to find PT is by using the proportion scale of 8
We will use 8 because GH ~ QP = = 8 and KG ~ RQ =
= 8
So we multiply 4 and 8 to get 32

Step-by-step explanation:
To add or subtract 2 fractions, they must have same denominators, if they not do that
- Find the Lowest common multiple of the two denominators (LCM)
- Replace each denominator by it
- Divide The LCM by each denominator and multiply the numerator of each fraction by its quotient
∵ ( x +
) + (
x -
)
- Let us start with adding the like terms
∴ ( x +
) + (
x -
) = (
∵ ( x +
x ) have same denominators, then we can add them
∴ ( x +
x ) =
x
∵ ( -
) do not have the same denominators, then we must find
LCM of 8 and 4
- The LCM of 8 and 4 is 8 because 8 is the first common multiple
of 8 and 4
∵ LCM of 8 and 4 is 8
- Divide 8 by the denominator 4
∵ 8 ÷ 4 = 2
- Multiply the numerator of the fraction by 2
∴
∴ ( -
) = (
-
) =
∴ ( x +
) + (
x -
) =
x +
The sum of ( x +
) + (
x -
) is
