Answer:
g
Step-by-step explanation:
It is a right triangle so,
a² + b² = x²
9² + 12² = x²
225 = x²
√225 = x
15 = x
Hope this helps :)
The answer is (x+1)x(3x-2)
cups of brown sugar needed for only 1 cup of flour
<em><u>Solution:</u></em>
To make banana bread, Colin uses
of a cup of brown for every 2 cups of flour
To find: Amount of brown sugar should Colin use to make a small batch with only 1 cup of flour
Let "x" be the amount of brown sugar needed for only 1 cup of flour
From given information,


This forms a proportion and we can solve the sum by cross multiplying

Thus
cups of brown sugar needed for only 1 cup of flour
Combine the two sets to form one giant set. If needed, toss out any duplicate values.
So,
A U B = {4,7,10,13,17, 3,5,7,9}
Toss out the duplicate item "7" and sort the values to get
A U B = {3,4,5,7,9,10,13,17}
