7 0

Answer:

Sometimes true

Step-by-step explanation:

This is only true for the numbers 0 and 1 because 0 squared is 0 and 1 squared is 1 making the different of their squares 1 and the difference of the numbers also 1.

For every other number combo this is untrue.

Factor. 3x2 + 20x + 25

algol [13]

Answer:

(3 x + 5) (x + 5)

Step-by-step explanation:

Factor the following:

3 x^2 + 20 x + 25

Hint: | Factor 3 x^2 + 20 x + 25 by finding factors of 3×25 whose sum is 20.

Factor the quadratic 3 x^2 + 20 x + 25. The coefficient of x^2 is 3 and the constant term is 25. The product of 3 and 25 is 75. The factors of 75 which sum to 20 are 5 and 15. So 3 x^2 + 20 x + 25 = 3 x^2 + 15 x + 5 x + 25 = 5 (3 x + 5) + x (3 x + 5):

5 (3 x + 5) + x (3 x + 5)

Hint: | Factor common terms from 5 (3 x + 5) + x (3 x + 5).

Factor 3 x + 5 from 5 (3 x + 5) + x (3 x + 5):

Answer: (3 x + 5) (x + 5)

1. If you knew that DE = $\frac{1}{2}$ CB
Then you would know it is a mid-segment.

2. If you knew that CD = DA and BE = EA (point D and point E are midpoints of their respective segments)

Use the number set to answer the question.

Fantom [35]

Answer:

Step-by-step explanation:

The median is the middle value of the data set arranged in ascending order.

If there is no exact value then it is the average of the values either side of the middle.

Arrange the data in ascending order

1, 4, 6, 8, 8, 9

The middle is between 6 and 8, thus

median = $\frac{6+8}{2}$ = $\frac{14}{2}$ = 7
