A and b are positive integers and a−b=2. Evaluate the following:
Nata [24]

Answer:

1/9

Step-by-step explanation:

You can put in any 2 numbers that would make a-b=2 true, so if you use a=4 and b=2, then 3^2/3^4=1/9. This is still true with any 2 numbers that make a-b=2 true. Hope this helps!

Implify the expression. write your answer using decimals. 22.5 + 7(n−3.4
Tresset [83]
An algebraic expression consists of variables which are represented with letters like for this case we have n, a coefficient which is indicated by numbers (e.g. 22.5, 7 and 3.4 ) and  sometimes exponents Oftentimes expressions contains a number of terms which consists of those elements. To simplify an expression, we need to remember that we can only add and subtract terms that have the same base of the variable. As for multiplying and dividing, we can proceed with these operations accordingly. We simplify as follows:

<span>22.5 + 7(n−3.4)
22.5 + 7n - 23.8
7n - 1.3

The simplified expression would be written as </span>7n - 1.3.

The figure shows a kite inside a rectangle. Which expression represents the area of the shaded region? 2x2 4x2 6x2 8x2
Savatey [412]
The picture in the attached figure

we know that
area of the <span>the shaded region=area of rectangle -area of a kite

area of rectangle=(3x+x)*(x+x)----> 4x*2x---> 8x</span>²

area of a kite=(1/2)*[d1*d2]
where d1 and d2 are the diagonals
d1=4x
d2=2x
so
area of a kite=(1/2)*[4x*2x]----> 4x²

area of the the shaded region=8x²-4x²-----> 4x²

the answer is 
4x²
