Divide both sides by -3, and replace
with
. Then

Factorize the quadratic in
to get

which in turn means

But
for all real
, so we can ignore the first solution. This leaves us with

If we allow for any complex solution, then we can continue with the solution we ignored:

Answer:
<u>The third option</u> 56
Step-by-step explanation:
56 is the middle number but I'm sorry if I'm wrong
Answer:

Step-by-step explanation:
Let x be the distance from the foot of the ladder to the base of the building.
We have a right triangle, so we can use Pythagoras' Theorem.

Answer:
y = 2|x+3| -2
Step-by-step explanation:
1) slope = rise/run= 4/2 =2 - for the right line
2) y = 2|x| initial graph
3) It is moved 3 units left
y = 2|x+3|
4) It moved 2 units down
y = 2|x+3| -2
