Answer:
2x² + 6x + 4
= 2(x² + 3x + 2)
= 2(x² + 2x + x + 2)
= 2[x(x + 2) + (x + 2)]
= 2(x + 1)(x + 2)
Step-by-step explanation:
well it would be 8b - 20 because you have to multuply by 4 on 5 too not just 2b
Answer:
-3h+4k+2
Step-by-step explanation:
We must subtract 2k from 6k to combine the like terms.
-3h+6k+2-2k
-2k -2k
-3h+4k+2
Since no other numbers can be combined this is our final answer.
Hope this helps! :)
Answer:
Step-by-step explanation:
let CP of the article = x
at 5% gain, SP of article = x + (5/100)x = 1.05x
at 5% loss, SP of article = x - (5/100)x = 0.95x
given that 1.05x - 0.95x = 16.5
⇒ 0.1x = 16.5
⇒ x = 16.5/0.1
⇒ x = Rs. 165.
The cost price of the article is Rs. 165.
3rd one.
6(x + 2) is simply 6x + 12
Do 12 + 7
You will get 19.
Now put that together.
6x + 19, which is option 3
Hope this helped! :D
