(2x-5)-(3-9x)=2x-5-3+9x=11x-8
Answer:
This is the “best” method whenever the quadratic equation only contains x2 terms.
The general approach is to collect all x2 terms on one side of the equation while keeping the constants to the opposite side.
step by step: but in order to solve a quadratic using the square root principle the problem must be in the correct form. To solve a quadratic using the square root principle the quadratic must be in vertex form, a(x – h)2 + k.

Answer:
3/20 or 15%
Step-by-step explanation:
Out of 1,2,3,4, and 5, there are 3 prime numbers. This makes the odds of selecting one of those prime numbers 3/5. Then, saying that he does pick a prime number and discards that card, there are now four cards, one of them being the number one. His chances of selecting this card is 1/4.
To find the probability you need to multiply the two probabilities together.
3/5 times 1/4 is 3/20.
So your answer is 3/20 or 15%.
The formula for the number of degrees of an external polygon is
360/n where n is the number of sides
octogon has 8 sides
360/8=45
answer is 45 degrees
