Step-by-step explanation:
When simplifying you want to combine like terms so 14x²-12x² will equal 2x², now we move on to X, where 3x+11x will result in 14x, last we add up numbers without X so 4-3 is 1.
The Answer will end up being 2x²+14x+1 (B)
Answer:153
Step-by-step explanation:
From the question, we are informed that Emilio asks his classmates what month they were born and that he finds that 15 out of 125 classmates were born in July. This gives us a fraction of 15/125 = 3/25.
If there are 1,280 students in Emilio's school, the number of students that he can expect to have birthdays in July would be:
= 3/25 × 1280
= 153.6
There will be 153 students expected
