Reflection over the x axis
Answer:
A = 26.66 ft^2
Step-by-step explanation:
Recall, please, that the formula for the area of a triangle of base b and height h is
A = (1/2)(base)(height).
Here,
A = (1/2)(8.6 ft)(6.2 ft) = 26.66 ft^2, or 26 2/3 ft^2.

"<span>Add or subtract. Be sure to reduce your answer: 5\6-9/20"...
To add or subtract rationals, you must find a common denominator of both fractions.
This can be done by multiplying the denominators by each other:
6*20=120
We must do the same operation to the numerators.
5*20=100
9*6=54
Now we can the subtract the rationals:

<span>=100-54/120
=46/120
=23/60
Hope this helps.
