Answer:
Option D = 5x= 25
Step-by-step explanation:
-1 + 26 = 25
-3y + 3y = 0
2x +3x = 5x
Hence, 5x +0= 25
5x = 25
Answer:
-2
Step-by-step explanation:
To find the slope you have to do (y2-y1)/(x2-x1).
So in this case (-7-11)/(5+4)
So the slope is -2
Answer:
5 11/36
Step-by-step explanation:
Answer:
Step-by-step explanation:
Square Root of 225 is 15 (with -15 also it would work but let’s stick to positive root)
Now, the 1st Odd Number is 15 -2 = 13 and the 3rd Odd Number is 15 + 2 = 17.
The required Numbers are 13 and 17.
This works for 3 consecutive Even Numbers also.
Why does it work?
Because, if we have 3 numbers to be a-2, a and a+2 (Doesn’t really matter if a is positive or negative)
(a-2)*(a+2) = a^2 - 4
So, you see adding 4 to the Product of the 1st Number and the 3rd Number (a^2 - 4 + 4 = a^2) gives you the square of the Middle Number, which is a^2!
