Answer:
a=-0.5
Step-by-step explanation:
Distributive property for left side, difference of squares for right side.
8a-9a^2=-40+36-9a^2
-9a^2 cancels out
8a=-4
a=-0.5
Each foot of the patio would be 49 feet because a square has four equal side lengths and 196/4=49. now don't put you'll whole faith in me, this is a good guess.
T is the midpoint of the line, meaning that in line SU, line ST and line TU are of equal length, since T is at the middle of the line.






Hope this helps. 頑張って!
Answer:
2.54 , 2 , 1/4 , -1.79 , -4
Step-by-step explanation:
5p + 9c = p
subtract 9c from both sides=> 5p + 9c - 9c = p - 9c
simplify=> 5p = p - 9c
subtract p from both sides=> 5p - p = p - 9c - p
simplify=> 4p = -9c
divide both sides by -9 (to isolate c) => 4p/ -9 = -9c/ -9
4p/-9 = c, or c = 4p/ -9
