Answer:
- (x+2) (x-2)=
-4
(n+m) (n-m)=
- (r+9) ( r-9)=
-81
Step-by-step explanation:
Given:
The given term is 3x.
To find:
The like terms.
Solution:
Like terms are the terms which contain same variable and degree.
In the given term 3x, the variable is x and its degree is 1.
The variable in 4y is y and, 8 and 0.257 are constant. So, 4y, 8, 0.257 and 3x are not like terms.
On 10 has variable x and degree 1. So, 3x and 10x are like terms.
Therefore, the correct option is B.
Answer:
√32 or partially rooted 4√2
Step-by-step explanation:
defined as..
√((x2-x1)²+(y2-y1)²)= distance between 2 points
√((5-1)²+(7-3)²)= √32
Answer:
By the Pythagoras theorem, the hypotenuse (c), is equivalent to:
a^2+ b^2= c^2 where a and b are the other two sides of the right angled triangle, hence c= square root (15^2+ 20^2)= 25
