Answer:
The answer is x= 9 and -3
You must fine 2 number that multiply to equal -27 and add to equal -6
(x-9) (x+3)
Then equal the parts of the binomial to zero
x - 9 = 0
x + 3 = 0
You must get x by its self.
When you do so, you'll have the answer as -3 and 9

Answer:
C. 74 sqft
Step-by-step explanation:
The bottom has a surface area of 4ft * 5ft = 20sqft
Theres two 3ft x 5ft sides and two 3ft x 4ft ones.
2 * 3ft * 5ft + 2 * 3ft * 4ft = 2 * 15sqft + 2 * 12sqft = 30sqft + 24sqft = 54sqft
Total surface of the outside is thus
20sqft + 54sqft = 74sqft
So if you need 1/2 cup for a 3-layer, then it means that you need a third of that for a one-layer. you need to divide 1/2 by 3. It is easier to get that if you use another form of 1/2, for example 3/6. In this case you simply divide this by 3 and you'll get 1/6.
Answer:
Then g = 5.
Step-by-step explanation:

2*5 - 4 = 6
So 2 x 5 = 10.
Which the equation is now 10 - 4 = 6.
So the answer is 5.
