Answer:
8x³ + 12x² - 16x - 16
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Distributive Property
Step-by-step explanation:
<u>Step 1: Define expression</u>
(4x² - 2x - 4)(2x + 4)
<u>Step 2: Simplify</u>
- Expand: 8x³ - 4x² - 8x + 16x² - 8x - 16
- Combine like terms (x²): 8x³ + 12x² - 8x - 8x - 16
- Combine like terms (x): 8x³ + 12x² - 16x - 16
Answer:
13-n=4
Subtract both sides by 13
-n=-9
n=9
Step-by-step explanation:
13 less means - and a number means n that you don’t know. is means = sign. And so we get the answer that I gave you. Thank you

Answer:
-29/20
Step-by-step explanation:
-9/4 = r - 4/5
-r = -4/5 + 9/4
-r = 29/20
r = -29/20
3 small boxes and 6 large boxes were sent to the retailer.
Step-by-step explanation:
Number of books held by small boxes = 30
Number of books held by large boxes = 40
Total books held by boxes = 330
Let,
x represent the number of small boxes
y represent the number of large boxes
According to given statement;
y = 2x Eqn 1
30x+40y=330 Eqn 2
Putting value of y from Eqn 1 in Eqn 2
Dividing both sides by 110
Putting x=3 in Eqn 1
3 small boxes and 6 large boxes were sent to the retailer.
