First, you can factor out the -. You then get
.
It becomes clear that this is a difference of squares. So, you can factor this to be
Plugging in the - into one of the two factors gives you
Therefore, the answer is A.
Hey there!
We can find the answer to this by finding how much is 3/4 of the sugar and subtracting that from the 20 pounds of sugar he started with.
3/4 in decimal form is 0.75, so we can multiply 20 by 0.75 to get 3/4 of 20.
0.75 x 20 = 15
This means 3/4 of the sugar is 15 pounds.
Now we can subtract that from the original 20 pounds he started with.
20 - 15 = 5
He has 5 pounds of sugar left.
Hope this helps!
Answer:
(-16x + 13)° + (-20x + 23)° = 180° ( St. angle)
-16x° + 13° - 20x° + 23° = 180°
-4x° + 36° = 180°
-4x° = 180°-36°
-4x° = 144°
-x° = 144°/4
-x° = -36°
x° = 36°
