Answer: 3x + 15
Step-by-step explanation:
In order to use the distributive property, you simply multiply the number on the outside by both the number inside the parenthesis
So, in this case, we would multiply 3 by X and 3 by 5
3 times x = 3x
3 times 5 =15
Your new equation is then made by adding these two together
3x+15
Answer 3x + 15
When variables with exponents are divided by each other, you subtract the exponents.
For example:
Answer:
B
285
9 = 7 + 2¹
13 = 9 + 2²
29 = 13 + 2⁴
285 = 29 + 2⁸
