2n^2+15n+7 in factored form

Mathematics
1 answer:
Korolek [52]3 years ago
7 0

Answer:

(2 n + 1) (n + 7)

Step-by-step explanation:

Factor the following:

2 n^2 + 15 n + 7

Factor the quadratic 2 n^2 + 15 n + 7. The coefficient of n^2 is 2 and the constant term is 7. The product of 2 and 7 is 14. The factors of 14 which sum to 15 are 1 and 14. So 2 n^2 + 15 n + 7 = 2 n^2 + 14 n + n + 7 = 7 (2 n + 1) + n (2 n + 1):

7 (2 n + 1) + n (2 n + 1)

Factor 2 n + 1 from 7 (2 n + 1) + n (2 n + 1):

Answer:  (2 n + 1) (n + 7)

Solve the equation square root X-6+2 = 6 for the variable. Show each step of your solution process
zhannawk [14.2K]
The first step would be to isolate the square root on the left side.  √x-6+2 = 6 √x-6 = -2+6  √x-6 = 4We would have to take away the radical on the left and square the equation.  (√x-6)2 = (4)2 x-6 = 16Finally, x -22 = 0 x = 22

Step-by-step explanation:

<u>Step 1: Define</u>

-15x + 5 = -10x + 25

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Add 15x on both sides:                    5 = 5x + 25
  2. Subtract 25 on both sides:              -20 = 5x
  3. Divide 5 on both sides:                   -4 = x
  4. Rewrite:                                             x = -4

Trey and Brandon each bought a new hockey stick for $80.
Gre4nikov [31]

Answer:

$4

Step-by-step explanation:

Trey sold his $80 hockey stick for 25% less. This means that he received 75% of the $80. Convert the percentage to a decimal, so it will be .75. Multiple .75 by $80 and you will get the final answer which is $60.

Brandon sold his $80 hockey stick for 30% less. This means that he received 70% of the $80. Convert the percentage to a decimal, so it will be .70. Multiple .70 by $80 and you will get the final answer which is $56.

Trey received $4 more for his hockey stick.
