A) (32x² + 24x +12) / 16. Notice that the GCD of 32, 24 and 12 is 4
then let's factorize:

4(8x² + 6x + 3) / 16. Now simplify numerator & denominator by 4

Hence a) = (8x² + 6x + 3) / 4

b) 35/(42x² - 49x +21); the GCD (of denominator) of 42, 49 and 21 is 7
then let's factorize:
35/[7(6x² -7x +3); Notice that 35 = 7.5 ; 7.5/ 7(6x²-7x+3)
Now simplify numerator & denominator by 7

Hence b)= 5/(6x²-7x+3)


Now do the same for the others.

Write an equation in point-slope form for the line that has a slope of 4/5 and contains the point (−5, −3).
ankoles [38]

y = mx + b, where m = slope, and b = y-intercept.

Since you are not given the y-intercept, you have to solve for it through the equation, y = (4/5)x (which is the slope you are given) + b, and replace x and y with values given, which are (-5,-3)

y = (4/5)x + b

-3 = (4/5)(-5) + b

-3 = -4 + b

1 = b


Then replace b in the first equation to get the answer

y = (4/5)x + 1
