C.
Because deceased means minus, so you eliminate A. Product means multiplication so 3n-7
Answer:
x=14
Step-by-step explanation:
-3+x=11
+3 +3
x=14
27. =
3,500,000 x 4,000 = 14,000,000,000
2x² + 13x + 15
First you multiply the first and last number, 2 · 15 = 30
Now you need to find the factors of 30 that add or subtract to +13(I added the plus sign to indicate that the factors that add/subtract to 13 must come out as positive 13)
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30 [1 · 30, 2 · 15, 3 · 10, 5 · 6]
You can do either 15 and 2 because 15 - 2 = 13, or 3 and 10 because 3 + 10 = 13.
I will be doing 10 and 3
2x² + 13x + 15 Instead of 13x, you can replace it with 3x and 10x because when you add it together it is 13x
2x² + 3x + 10x + 15 Now you can factor them out separately
x(2x + 3) + 5(2x + 3) You can factor out (2x + 3) from x and 5 to get:
(2x + 3)(x + 5)
Answer:
( x - 6 )² - 35
Step-by-step explanation:
x² - 12x + 1
→ Half the middle term and place it inside the bracket
( x - 6 )² + 1
→ Square it
( x - 6 )² - 36 + 1
→ Simplify
( x - 6 )² - 35
