Answer:
the answer to the question is 15$
The area of a square can be calculated by using this formula:
Where "s" is the length of a side of the square.
In this case, you can identify that:
Then, in order to estimate the area of the square, you can follow these steps:
1. Round the length "s" to the nearest whole number. Since the first digit after the Decimal point is 7 and:
You must round up:
2. Knowing that:
You can determine that:
Hence, the answer is: Option C.
Answer:
See below in bold.
Step-by-step explanation:
(A) 20 -4x=12 -x+8-3x
-4x + x + 3x = 12 + 8 - 20
0 = 0 This is an Identity.
Infinite solutions.
B). 5x+4x-3=24+8x
9x - 8x = 24 + 3
x = 27. One solution.
C. 5x+6=2x+6+3x-15
5x - 2x - 3x = -15 + 6 - 6
0 = -15
No solution.
Well the way I multiply bigger numbers is like this...
43 x 42
43
42
3 times 2 equals six
then 4 times 2 is 8
then add your zero place
then 4 times 3
and then 4 times 4
Or..something like this.
