The correct answer is no.
Area of square = x^2
If length is multiplied by 3, then each side of square is now 3x
new Area = (3x)^2 = (3x)*(3x) = 9x^2
So the Area has increased by a factor of 9.
In general, the Area will always increase by a factor which is the square of the factor applied to the side length.
Since its adding and subtracting just add the coefficients of similar terms (coefficient is the number in front, term is the coefficient and variables, similar terms are terms that have the same variables)
3ab-9ab+7ab
3-9=-6: -6ab+7ab
-6+7=1: 1ab or ab :)
Answer:
5 and 7
Step-by-step explanation:
<u>Fast and loose</u>: 12 is written as a sum of two odd numbers as 1+11; 3+9; 5+7. The only consecutive pair is 5 and 7
<u>Let's use algebra</u>: let's call 2n+1 the first and 2n+3 the second.
Their sum is 2n+1 +2n+3 = 4n+4 = 12. Thus, n+1=3 and n= 2. It means the 2 numbers are 2x2+1 =5 and 2x2+3 =7
