Use the difference of squares factor rule to get
4x^2-9y^4
(2x)^2-(3y^2)^2
(2x-3y^2)(2x+3y^2)
The final answer is choice C
Note: the order of the factors does not matter
Answer:
234 times
Step-by-step explanation:
<u>Number of times the number 7 appears in a hundred</u>
7 as units digit (07-17-27 ..... 97): 10 times
7 as tens digit (70-71-72..... 79): 10 times
20 times the digit 7 appears in first one hundred (0-100)
Let's calculate how many times 7 would be as units or tens in 7 hundreds
20X7 = 140 times digit 7 appears until number 699
<u>Now, from 700 to 777</u>
7 as hundreds digit (700-701-702 .... 777): 78 times
7 as tens digit (770-771-772 .... 777): 8 times
7 as units digit (707-717-727....777): 8 times
78 + 8 + 8 = 94 times the digit 7 appears in the range 700 - 777. Plus 140 times
140 + 94 = 234 times

Hello from MrBillDoesMath!
Answer: Perimeter = 17x + 4
Discussion:
(So you are trying to sneak #2 out of me too..... );
Perimeter = sum of lengths of sides. Starting at the bottom of the figure and proceeding counterclockwise.
Perimeter = (3x +2) + (3x+2) + (4x-1) + (4x-1) + (3x + 2) .
Separate and combine x's and constants:
Perimeter = (3x + 3x+4x+4x+3x) + (2 + 2 -1 -1 + 2) =
= 17x + 4
You answer has the wrong constant value ( you wrote 17x + 1. The constant should be 4)
Thank you,
MrB
