Answer:
y(3x + 4y)(x + 8y)
General Formulas and Concepts:
<u>Alg I</u>
Step-by-step explanation:
<u>Step 1: Define expression</u>
3x²y + 28xy² + 32y³
<u>Step 2: Simplify</u>
- Factor out <em>y</em>: y(3x² + 28xy + 32y²)
- Factor trinomial: y(3x + 4y)(x + 8y)
- What multiplies up to 32 adds up to 28 with 3 being multiplied as a coefficient? Numbers are 4 and 8.
Answer:
True.
Step-by-step explanation:
[0, 1] means all numbers in between 0 and 1, 0 and 1 included.
A probability is always a number in that interval. For example: 0.384, 0.222, 0.938, etc!
Answer:
$8.20
Step-by-step explanation:
0.70*4=2.80
1.80*3=5.40
5.40+2.80=8.20
$8.20
Answer:
AD = 3
Step-by-step explanation:
Pythagoras theorem formula: a² + b² = c² (c being the hypotenuse, the longest side of the triangle).
Using this formula, you can easily say that c²-b²=a². c=5, b=4, making the equation 5² - 4² = a ².
Expanding the formula, you'll get 25 - 16 = a².
25 - 16 = 9.
This means that 9 = a².
To find a, you need to root 9. Using a calculator, you'll know that this number is 3, meaning that AD = 3.
