Answer:
1. f (2) = 3 x 2^x-1
2. f (-1) = -3 x 2^x
3. f (10) = 3 x 2^x/10
Step-by-step explanation:
Answer:
100
Step-by-step explanation:
First, you look at wether the first digit in this case is above or below a 5. Since it is, you would round up. The closest hundred to this number is 100, so that is the answer. For 3 digit numbers or higher, look at the tens place to determine the nearest hundred. Same rule applies for rounding up or down.

40+5=45 is written in extended form so your answer is 45
Answer:
x² + 10x + 25
Explanation:
Before we begin, remember the following:
(a + b)(a + b) = (a + b)² = a² + 2ab + b²
Now, for the given we have:
(x + 5)(x + 5)
We can note that the two brackets are identical.
Therefore, we can apply the above rule as follows:
(x + 5)(x + 5) = (x + 5)²
= (x)² + 2(x)(5) + (5)²
= x² + 10x + 25
Hope this helps :)
