The answer is 3x-3. You have to distribute the 3 to both of the variables in the equations. The 1 in the parentheses is a negative and multiplying the 3 will result in a negative 3.
The correct option is -33/65.
The solution is given below:
Answer:
Step-by-step explanation:
a)
- 1.5x² + 6x + * =
- 1.5(x² + 4x + *) =
- 1.5(x² + 2*2x + 4) =
- 1.5(x + 2)²
- * = 1.5*2² = 6
b)
- 2x² - 5x + * =
- 2(x² - 2.5x + *) =
- 2(x² - 2*1.25x + 1.25²)=
- 2(x - 1.25)²
- * = 2*(1.25)² = 3.125 or 25/8

a.
60 ounces = 3 pounds
So no, you don’t have as much fruit as you need.
b.
60 ounces —> 3 pounds
X ounces —> 4 pounds
Cross product :
(60 x 4) / 3 —> 240/3 = 80
So in order to have 4 pounds of fruits, you need 80 ounces of fruits.
You already have 60 ounces of fruits.
X + 60 = 80
80 - 60 = X
20 = X
You need 20 more ounces to have 4 pounds of fruits.
