Sara is working on a Geometry problem in her Algebra class. The problem requires Sara to use the two quadrilaterals below to ans
zloy xaker [14]
Part A:

Given a square with sides 6 and x + 4. Also, given a rectangle with sides 2 and 3x + 4

The perimeter of the square is given by 4(x + 4) = 4x + 16

The area of the rectangle is given by 2(2) + 2(3x + 4) = 4 + 6x + 8 = 6x + 12

For the perimeters to be the same

4x + 16 = 6x + 12
4x - 6x = 12 - 16
-2x = -4
x = -4 / -2 = 2

The value of x that makes the <span>perimeters of the quadrilaterals the same is 2.



Part B:

The area of the square is given by

Area=(x+4)^2=x^2+8x+16

The area of the rectangle is given by 2(3x + 4) = 6x + 8

For the areas to be the same

x^2+8x+16=6x+8 \\  \\ \Rightarrow x^2+8x-6x+16-8=0 \\  \\ \Rightarrow x^2+2x+8=0 \\  \\ \Rightarrow x= \frac{-2\pm\sqrt{2^2-4(8)}}{2}  \\  \\ = \frac{-2\pm\sqrt{4-32}}{2} = \frac{-2\pm\sqrt{-28}}{2}  \\  \\ = \frac{-2\pm2i\sqrt{7}}{2} =-1\pm i\sqrt{7}

Thus, there is no real value of x for which the area of the quadrilaterals will be the same.

The sum of two consecutive integers is less than 55 the pair of integers with the greatest sum are 26 27
gayaneshka [121]

Answer:

28

Step-by-step explanation:

Let first integer = x

so second integer = x + 1

according to question we get the equation,,,,

(x) + (x + 1) < 55

x + x + 1 < 55

2x + 1 < 55

subtract 1 from both sides ,we get

2x < 54

divide both sides by 2 we get ......

x < 27

1st integer = x and x < 27

also as we need sum of integer with greates sum so we take x = 26

and 2nd integer = x+1

= 27 + 1

= 28

now if you add both the integers you get sum = 54 which is less than 55 and so this verify you second condtion also .......

hope this will help you

Please feel free to revert back for any further queries.
