How do I determine whether each binomial is a difference of two squares

Answers

Answer 1
Answer: A binomial is a difference of two squares if it can be written as a^2 - b^2. Note the subtraction sign. For example 9x^4 - 16 = (3x^2)^2 - 4^2 so it is a difference of two squares.

The sum of a number b and 3 is greater than 8 and less then 12

Answers

The sum of a number b and 3 is greater than 8 and less than12=> b + 3 < 8
=> b + 3 > 12

Now,let’s combine this into an expression:
=> 8 < b+3 < 12
=>  (8 - 3) < b < (12 - 3)
=> 5 < b < 9
Thus, the answer in the given situation is 9 because 9 is greater than 8 butless than 12.

Based on the graph, which statement is correct about the solution to the system of equations for lines K and J?(1, 1) is the solution to both lines K and J.
(−1, 0) is the solution to line K but not to line J.
(1, 1) is the solution to line K but not to line J.
(0, 4) is the solution to both lines K and J.

Answers

The answer is (1,1) since that is where J and K intersect.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Nina earns $15 for each yard she mows.

She wants to buy a dress that is $109.

so, she needs to mow

= 109/ 15

= 7.266 yards

Hence, Nina needs to mow 7.266 yards of lawn.

Step-by-step explanation:

Step 1: Define

Point (3, 6)

Point (4, 2)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m.

  1. Substitute [SF]:                    m=(2-6)/(4-3)
  2. Subtract:                              m=(-4)/(1)
  3. Divide:                                 m=-4
