Step-by-step explanation:

-12.3 - 14.2 =

in addition or subtraction, if the signs are alike, u add them and keep the same sign

15 POINTS!
joja [24]
8x + (2x - 14)= 7x + 3x -14

10x -14= 10x - 14

These equations are identical, so it would be the  identity property and the answer would either be identity or the fancy 'R'.

Find the area.<br> help pls
lions [1.4K]

Answer:

81.6 inches squared

Step-by-step explanation:

The formula for calculating all parallelograms is Area+=base*height.

The height is given to you, 6.8, the base of the figure is also given, 12.

Now all you have to do is to multiply.

That would get you to 81.6.

(When asked for area of parallelogram, the length of any line other than the height and base is not needed)

hoped this helped!
