For this case, the first thing we should do is use the following equation:
x ^ 2 + x-30
Here, we substitute the value of x = 20
We have then:
(20) ^ 2 + (20) -30 = 390 m ^ 2
Answer:
the area of the land when the length of the dentist's office is 20 meters is:
390 m ^ 2
Answer:
b. divide each side by 4.75
Step-by-step explanation:
4.75x = 24.7
divide each side by 4.75
x = 5.2
check your work
4.75(5.2) = 24.7
24.7 = 24.7
1/2 * 1/2 = 1/4 there is a 25% chance that they will both occur
