Answer:
Step-by-step explanation:
- 20 - 15(2²· 5/4) = Exponent
- 20 - 15(4 · 5/4) = Parenthesis
- 20 - 15(5) = Multiplication
- 20 - 75 = Subtraction
- - 55
The pens were 20% off of the original price
Distribute
x^2 + 5x+ 3x+ 15
Add like terms
x^2+8x+15
Answer:3
Step-by-step explanation:if it is 3 cubes tall that means it will be 3 cubes
This question explores something known as exponential growth, and is often used to determine compound interest after a period of time.
We can use equation
y = xr^n
Where y is the value after n years, x is the initial value and r is the percentage growth each year.
By substituting
1462 * 1.03^10
We get a value that rounds to 1965, so your answer is D.
