Step-by-step explanation:
23x + xy - y + 3y + 5 - 20x + 6xy = 23x - 20x + xy + 6xy -y + 3y + 5
= 3x + 7xy + 2y + 5
Errors:1) The combined coefficients of the x terms should be 3x, not 43x
2) The coefficients of the y terms have been multiplied.
3) The constant was left off.
To find the perimeter of the triangle, you will add the lengths of each side.
We know two of the sides are 16.2 cm. We also know that the third side is half this (16.2/2) or 8.1 cm.
16.2 cm + 16.2 cm + 8.1 cm = 40.5 cm
The perimeter of the triangle is 40.5 cm.
