Answer:
A. y = -8x -5
Step-by-step explanation:
You will notice that when x increases from 2 to 5, y decreases from -21 to a number that is more negative. Thus only the first two answer choices are possibilities, since the others have a positive coefficient for x.
Trying the first given point in the first answer choice, we see that it works:
-21 = -8·2 -5
so, that is the equation we're looking for.
y = -8x -5
Rewritten: 4(5.75 + 4.25)
solved: 4(10) = 40
explanation: it was easier this way because we did not have to work with decimals
Answer:

Step-by-step explanation:
GIVEN: The length of each side of a square is
inches more than the length of each side of a small square. The sum of the areas of the square is
inches.
TO FIND: the lengths of the sides of the two squares.
SOLUTION:
let the length of side of small square be 
Area of small square 
As length of each side of bigger square is
more than the smaller square
length of side of bigger square 
Area of bigger square 
Also
Sum of areas of both square 




as the length of side can never be negative

length of side of smaller square 
length of side of bigger square 

Hence the length of smaller and bigger square are
and
respectively.
