Answer 2

Answer:

6 no. answer

4+3x 3x sq. -5x

5-4x+2xsq. -x +2x+5

__________.(add) __________(add)

9-x+2xsq. 2x sq. -3x+5

Step-by-step explanation:

2x sq. - X+9

2x sq.+- 3x+-5

sub. 2x+4

OR

{(4+3x) + (5-4x + 2x sq.)} - { (3x sq. - 5x sq. ) + (X sq. + 2x+5)}

= 4+3x+5-4x+2x sq. -3x sq. +5x+ X sq. - 2x-5

=4+3x-4x+2x sq. +5 - 3 X sq. + x.sq. + 5x -2-5

( rearranging the terms )

= -x + 2x sq. +9 - 3 X sq.+3x-5

=2x +4..... ANSWER

7. NO ANSWER

Given -

Four sides are..

(X+4) , (2x -2), (3x-8) ,( 40-5x)

perimeter of quadrilateral is - sum of the total

perimeter of quadrilateral is

(X+4) + (2x-2) + (3x-8) + (40-5x)

= X+2x+3x- 5x-2 -8-40

= 6x+5x+4+40-10

=X+44-10

=X+34.... ANSWER

HENCE THE PERIMETER OF QUADRILATERAL IS( X+34)..

HOPE THIS WILL HEPS U MATE ❣️
