Answer:
8
Step-by-step explanation:
number of rooms=6÷3/4=6×4/3=8
Z=4t-5
z+t=180
z= 180-t
4t,-5=180-t
5t=185
t=37
180-37=z = 143
Just solve the quadratic, you need to figure out what value you can use to FOIL and get c^2+5c-24=0. so you need to figure out what values you can add together to get 5 and multiply together to get -24 so try (c+8)(c-3) here 8 and 3 make sense since 8-3 = 5 and 8*-3=-24 so the answer is (c+8)(c-3).
