Answer:
11
Step-by-step explanation:
Given
x² - 7x + 10 = 28 ( subtract 28 from both sides )
x² - 7x - 18 = 0 ← in standard form
(x - 9)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 9 = 0 ⇒ x = 9
x + 2 = 0 ⇒ x = - 2
The distance between the solutions is
| 9 - (- 2) | = | 11 = 11 units
Answer: 32 people will ride on each bus.
Step-by-step explanation: First, you need to add the total amount of people going on the bus. You add the number of students and adults. 267 kids + 21 adults = 288 total people. Now, you divide 288 by 9 and get 32. That means 32 people will ride on each bus.
Technically, is infinite because you could assign one person to more that one group
Answer:
E= 49
F= 90
D=90
Step-by-step explanation:
To find F and D you need to divide 180 by 2. To find E you need to subtract 131 from 180.
Answer:
18 edges
Step-by-step explanation:
v-e+f=2
