Subtract these polynomials. (6х2 – ҳ+ 8) — (х2 + 2) = а. 7х2 – x+6 в. 5х2 – x+ 10 с. 5x? - x+6 d. 7x2-x+ 10

5 x^2 - x + 6

Step-by-step explanation:

- (x^2 + 2) + 6 x^2 - x + 8

- x^2 - 2 + 6 x^2 - x + 8

(6 x^2 - x^2) - x + (8 - 2)

5 x^2 - x + (8 - 2)

= 5 x^2 - x + 6

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
