(a^(2)-4ac+3bc)/(a^(2)-ab+bc-ac)+(a +3b)/(b-a)+(a+2c)/(a-c)

The answer is −a^4 + 5a^3b + 2a^3c − 4a^2b^2 − 10a^2bc − a^2c^2 + 8ab^2c + 5abc^2 − 4b^2c^2  / −a^4 + 2a^3b + 2a^3c − a^2b^2 − 4a^2bc − a^2c^2 + 2ab^2c + 2abc^2 − b^2c^2

Step-by-step explanation:

This the equation being simplified

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
