Answer:
(n + 1)(3n + 7)
Step-by-step explanation:
3n² + 10n + 7
Consider the factors of the product of the n² term and the constant term which sum to give the coefficient of the n- term.
product = 3 × 7 = 21 and sum = + 10
The factors are + 3 and + 7
Use these factors to split the n- term
3n² + 3n + 7n + 7 ( factor the first/second and third/fourth terms )
3n(n + 1) + 7(n + 1) ← factor out (n + 1) from each term
= (n + 1)(3n + 7) ← in factored form
<u>Answer:</u>
The correct answer option is B. Construct a line perpendicular to XP through point A.
<u>Step-by-step explanation:</u>
We are given an incomplete figure of construction of a perpendicular line and we are to determine whether which of the given answer options is the next step in the construction.
From the given marks, we can deduce that a perpendicular line to XY is being constructed, passing through P.
So the next step must be to construct a line perpendicular to XP through point A to complete the construction.
Answer:
1). 1.25 / 250 = .005M
.005 = 1 liter
2). (20)(.5) = 10M

The answer is
C. - (x + 3)(x - 4)
because if you solve this....
- (x + 3)(x - 4)
(-x - 3)(x - 4)
-x^2 +4x - 3x + 12
-x^2 + x + 12
2/9=0.222.....
it is alot closer to zero than any of ther other numbers
