Answer:

Step-by-step explanation:
To factor this, you must first take out the GCF (Greatest Common Factor), that
and -147 both have. The terms only have 3 in common, which can be divided with

However, we're still not done since 49 is a perfect square and
can be split into 2, like so:

If you're unsure about the final answer, you can multiply it all together to see if you got the original expression.
Answer:
x = ± 1
Step-by-step explanation:
Given
3(x² - 4) + 7 = - 2 ( subtract 7 from both sides )
3(x² - 4) = - 9 ( divide both sides by 3 )
x² - 4 = - 3 ( add 4 to both sides )
x² = 1 ( take the square root of both sides )
x² = ±
= ± 1
Thus
x = - 1, x = 1

Answer:
<u>Option A</u>
Step-by-step explanation:
To reflect line segment BC over line m, BB' will be perpendicular to the line m
and line m bisector of BB'.
<u>So, the correct answer is option A</u>
A) Line m is the perpendicular bisector of line segment BB' and the line segment CC'
<u>Option b is wrong</u> , it is impossible for the line B'C' to be perpendicular to line BC. B'C' is the image of BC.
<u>Both option c and d is wrong</u> because the perpendicular distance from b to the line m not equal to the perpendicular distance from c to the line m.
