Answer:
- 1 5/24 cm
Step-by-step explanation:
We'll have to get the fractions to a common denominator. the least common denominator for 3 and 80 is 240.
So - 1 1/3 = - 1 80/240 = 320/240
21/80 = 63/240
-11/80 = -33/240
-------------------------------------
-320/240 + 63/240 - 33/240 = -290/240 = - 1 50/240 = -1 5/24 cm
(-2x+10Y)(4X-6Y) can be simplified as -8x+-60Y because you have to combine like terms such as -2x and 4x.
