1/2(5x + 12) = 2x - 3
5/2 x + 6 = 2x - 3
5/2 x - 2x = -3 - 6 = -9
5x = 2 x -9 = -18
x = -18/5
Answer:
8900000 * 10^-3
Step-by-step explanation:
(8.9*10^-3)/(10^-6)
(8.9*10^-3)/(1/1000000)
8.9*10^-3* 1000000
8900000 * 10^-3
-4 is the x intercept.as in the values on the x-axis
The 2 rooms only add up to 45,000 square feet (150 x 150 x 2) and the larger room is only 40,000 square feet (200 x 200) so this only gives you 85,000 square feet (40,000 + 45,000) which is not enough for the 100,000.
