Answer: -x² + 21x + 27
Step-by-step explanation:
Multiply by 3:
-x² + 27 + 21x
Answer:
Step-by-step explanation:
We will prove this with the help of a contradiction:
Let as assume that 
Multiplying both sides by 
which is not possible.
Hence, our assumption was wrong which led us to a contradiction.
Thus,
Make a table with two columns, to find the ordered pair. This is an example.
Answer:
9 1/3, 12 1/2, 14 3/4
Step-by-step explanation:
I assume the formula you’re working with is A=b*h since nothing says otherwise...
((Patio 1))
So you have your area (147) and your base (15 3/4), now you need to plug them in, which should look like this:
147= 15 3/4*h
You need to isolate your h in order to get the missing number, so you should divide both sides by 15 3/4 OR 63/4 ((15*3—>60+3=63))
Dividing by a fraction is the equivalent of multiplying by its reciprocal... so
147 * 4/63 = 588/63 which can be simplified to 84/9 once both the numerator and denominator are divided by 7
In mixed number for it is 9 3/9 which simplified becomes 9 1/3
You solve the other similarly
