Answer:
Answer a
Step-by-step explanation:
Since there is a radical in the first fraction, we need to multiply it by the same radical in the denominator of another fraction to get rid of the root.
Chang is incorrect because his factoring results in -21 instead of positive 21.
Benjamin is incorrect because his factoring results in positive 9x instead of -9x.
Habib's answer is incorrect because 4 + 12x is not equivalent to the expression above.
A correct factor would be: 4-3(3x-7)
The answer is $5.25 or .75 cents each
Answer:
45
Step-by-step explanation:
46
Ratio of rise can also mean the slope so let's find the slope given the two points.
slope formula;
m = y2 - y1/ x2 - x1 (3, 4), (-2, 0) (x1, y1), (x2, y2)
m = 0 - 4/ -2 - 3
m = -4/-5
m = 4/5
so your answer is B.
hope this helps, God bless!
