<h3>
Answer: (2x-y)(2x+y)</h3>
===========================================
Work Shown:
4x^2 - y^2
(2x)^2 - (y)^2
(2x-y)(2x+y)
When going from the second step to the third step, I used the difference of squares rule. That rule is a^2-b^2 = (a-b)(a+b). In this case, a = 2x and b = y.
Side note: (2x-y)(2x+y) is the same as (2x+y)(2x-y). We can multiply in any order.
Answer:
Step-by-step explanation:
<h3>Q1</h3>
<u>The ratios of corresponding sides of similar figures are equal:</u>
- x / 25 = 24 / 15
- x / 25 = 8 / 5
- x = 25*8/5
- x = 40
<h3>Q2</h3>
<u>Short sides are x and 15, long sides are 36 and 24. The ratios are same:</u>
- x / 15 = 36 / 24
- x / 15 = 3/2
- x = 15*3/2
- x = 22.5
Correct choice is C
IDK IDK IDK IDK I DONT KNOW
Firstly, solve 38C15.
Then solve 42C12.
Compare your answers.
The goal here is to see if 38C15 = 42C12.
Here is the formula:
nCr = n!/(r!(n - r)!
Go for it.
