X2+12x+35 should be written as <span>x^2+12x+35, where "^"
denotes exponentiation.
Since the coefficient of the x^2 term is 1, we can focus on 35, finding its factors. Note that 35 = 1*35, 5*7. Also note that 5+7 = 12.
Thus, </span>x^2+12x+35 can be re-written as (x+5)(x+7). As a check, multiply 5 and 7; you get 35, which matches the original <span>x^2+12x+35. Then add 5x to 7x, obtaining 12x, which also matches.</span>
The scientific notations is 2.9x10^9
The sum of the angles of an n-sided polygon is (n-2)×180°
For a 30-gon, it would be 28x180 = 5040, answer B
Second question is more of a trick question. Exterior angles always add up to 360. So answer H.
Answer:
y=8
Step-by-step explanation:
add 36 to 12. then divide 48 (the result) by 6 to get 8
