Determine whether each Identity is true or raise. (2 pommes) True
False
a3 – 63 = (a - b) (a² + ab + b)
a² + 2ab + b2 = (a + b)(a + b)
O
a? – 2ab + b2 = (a + b)(a - b)
a? – b2 = (a + b)(a + b)
O

i think asking google will you get the answer to that question

5/12

step-by-step explanation:

give them both a common denominator so you get 9/12 and 4/12. subtract 9/12 from 4/12 to get 5/12.

perpendicular to x*4 means it's y = -1/4*x+k

so for y = 7 and x = 2

we have 7 = -1/4*2 + k so k = 7.5

so the equation is   y = -1/4x + 7.5
