Answer:
The two expression to represent area is (5 x - 10) sq. units or 5( x- 2) sq. units
Step-by-step explanation:
Here, the length of the rectangle = (x-2) units
The width of the rectangle = 5 units
Now, AREA OF A RECTANGLE = LENGTH x WIDTH
So, here AREA = 5 ( x- 2)
= (5 x - 10) sq. units
( as by Distributive property: A (B-C) = AB - AC)
Hence, the two expression to represent area is (5 x - 10) sq. units or 5( x- 2) sq. units
Answer:
x^2-6x+9 = (x-3)^2
4m^2-4m+1= (2m-1)^2
Step-by-step explanation:
Answer:
The values of x and y is given by the equation 
.
Step-by-step explanation:
Given : Five whole numbers are written in order 4 6 x y 10
, the mean and median of the five numbers are the same.
To find : The values of x and y ?
Solution :
Observations 4, 6, x, y, 10.
Mean is summation of observation divided by number of observation.
i.e. 
Median is middle term of observations.
Median of odd terms 
term
term
The mean and median of the five numbers are the same.
i.e. 
The values of x and y is given by the equation .
first the square root of 4 is 2 so we can sub that in.
now we have 2(2*2)^-2.
2 * 2 of course is 4
with 2(4)^-2, keep in mind that negative exponents just mean to "flip" the number and turn the exponents positive.
so 4^-2 is the same as 1/4^2 or 1/16.
finally 1/16 * 2 = 2/16. 2/16 simplified is 1/8.
