If you mean (3x-4)^2, the answer will be 9x^2 - 24x + 16.
Answer:
yes
number of tiles needed = (200 x 200) / (30 x 30) = 44.4
Step-by-step explanation:
number of tiles needed = Area of comfort room / area of tiles
Area of a square = length²
convert area of comfort room to cm
100 cm = 1 meter
2 x 100 = 200
number of tiles needed = (200 x 200) / (30 x 30) = 44.4
50 tiles are more than enough to tile the room
If the negative square root is found to be one of your solutions, then that is indicative of a pair of imaginary roots (the imaginary i). According to the conjugate rule, if you have one solution that is imaginary, you will have another but with the opposite sign. For example, if a solution to a quadratic is found to be 2 - i, then its conjugate, 2 + i is also a solution. They will ALWAYS go in pairs. Same thing with radical solutions. If one solution is found to be 
then
will also be a solution.
Step-by-step explanation:
15=2c+7
15-7=2c
8=2c
8/2=c
4=c
c=4
There is two ways to attempt this problem. The first is that you could prove that angle CDE is congruent to angle DAB (of which I'm not totally sure is possible) or option two. Your second choice is to prove that Line segment DE is a flat line because line segment AB is also a flat line.
