Factorize <br><br> cos2A - 5 cosA + 6
Tamiku [17]

Answer:

Let's assign the variable x to cosA. The expression then becomes x² - 5x + 6. To factorize this we need to find two numbers that have a sum of -5 and a product of 6; these numbers are -2 and -3 so the expression becomes (x - 2)(x - 3). Since we know that x = cosA the final answer is (cosA - 2)(cosA - 3).

1) v=1 (Add 10 to both sides of the equation. You should get -9+10, which makes the answer 1)

2) v=7 (like number 1, add 10 to both sides of the equation. 10+-3=7)

3) x=7 (add 3 to both sides of the equation. 4+3=7)

4) m=29 (divide -377 by -13, you should get 29)

5) b=6 (add 7 to both sides of the equation. 7+-1=6)

6) p=5 (add 13 to both sides of the equation. 13+-8=5)

7) p=8 (divide 40 by 5)

8) a=-19 (Divide 418 by -22. The answer is -19.)

10. Daniels goes to the shopping center. He has a bank account with a
Savatey [412]

Answer:

-$36

Step-by-step explanation:

Daniel has a starting balance of $259, so anything he spends will be deducted by this amount. To find out how much he spent, we need to add up everything he bought.

He spent $45 + $150 + $100, adding to a grad total of $295.

To find out how much money Daniel has left, we need to subtract his purchases from his funds. This would be $259 - $295. This leaves you with a final answer of -$36 in Daniel's bank account.
