Pulling out like terms
3.1 Pull out like factors :
2x4 - 50 = 2 • (x4 - 25)
Trying to factor as a Difference of Squares:
3.2 Factoring: x4 - 25
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 25 is the square of 5
Check : x4 is the square of x2
Factorization is : (x2 + 5) • (x2 - 5)
Answer:
A (3, 4) B (4, 2) C (0.5, 0.25) D (1, 2.5) E (1.75, 4.25)
Step-by-step explanation:
The coordinate points of a point are (x, y) where x is the number on the x-axis and y is the number on the y-axis.
By looking at points A and B they're easy to tell.
For points C, D, and E they're in between whole numbers so by converting the number given which is a fraction you can get 0.25 from 1/4 which is half of 1/2, 0.5 from 1/2, 0.75 from 3/4 which is half of 1/2 plus 1/2, 1.25 from 1 1/4, etc....

Answer: MAYBE <em>its 126</em>
Step-by-step explanation: The answer that I believe is- uh- idk. But what I know is that Terrell has 340 in total. He reads 253 in total also. But the question is "How many pages did Terrell read between lunch and dinner". Well I don't get this question very good but I think you subtract 253 to 127 which you get 126. If you don't think this is right, do 126 plus 127 which is 253. If I get this answer wrong I'm sorry, but this question is confusing.
Answer:
The probability the code is 14z is .
Step-by-step explanation:
Probability is calculated using the following fraction:
In this case, we are looking at three independent, combined events. This means that each pick of a number or letter does not depend on the previous event, but that the probability of each is linked, so we must multiply each probability together to get the total probability of the compete code. Since the numbers are 00 to 49, there are five total outcomes for the first number (0, 1, 2, 3, 4) and ten total outcomes for the second number (0, 1, 2, 3, 4, 5, 6, 7, 8, 9). The total outcomes for the letter selection would be 26, since there are 26 letters in the alphabet. Now, we multiply each probability together:
