Answer:
B. 11.4
Step-by-step explanation:
By using the line segment formula
AC = √(9-(-2)^2+(2-5)^2
AC = √130
AC = 11.4
Answer: a) 4b+6
The perimeter is the sum of the sides,
P = b+2 + b+1 + b+2 + b+1
P = 4b + 6
Answer:
Step-by-step explanation:
If there needs to be 4 teachers per 21 students, you would divide the total amount of students by 21 and multiply that answer by 4. SO...:
84 ÷ 21 = 4 groups of 21 students.
4 groups × 4 teachers = 16
*** Answer***
16 TEACHERS
X²+3x-28=0
(x+1.5)² - 1.5² - 28 = 0
(x+1.5)² - 25.75 = 0
(x+1.5)² = 25.75
Note: The answer is not listed on the option given. Maybe worth checking the if the original equation has been copied correctly.
