Answer:
(x-3)(x+5)
Step-by-step explanation:
x²+2x-15 find two numbers that add to make +2 and make a product of -15
-3×5=-15
-3+5=2
(x-3)(x+5)
Answer:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Answer:
24
Step-by-step explanation:
She visits 3 temples one by one
She offers 1/2 of what she has in the baske
- So 1/2 to the first
- 1/2 of 1/2 to the second =1/4
- And 1/2 of 1/2 of 1/2 to the third 1/8
She is left with 3 flowers
If she gave 1/2 of what she had left to the 3rd, and the other half was 3
Then it means she gave the 3rd 3 flowers
So 3 is 1/8th of what she had at the beginning
Multiply 3*8 and you get 24
Hope this helps ^_^

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = x² + 1
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(a + 1) = (a + 1)² + 1
- Expand [FOIL]: f(a + 1) = a² + 2a + 1 + 1
- Combine like terms: f(a + 1) = a² + 2a + 2
