The triangle is an equiangular triangle so that means it must be an equilateral triangle.
3x - 3 = x + 8
2x = 11
x = 5.5
BC = 3(5.5) - 3
BC = 13.5
Answer:
Step-by-step explanation:
1) If you really meant X^2+12=40, then this simplifies to x^2 = 28, and therefore x = ±√28, or x = ±2√7.
2) If you meant X^2+12x=40:
a) Take half of the coefficient of x: that would be (1/2)(12), or 6.
b) Square this result, obtaining: 6² = 36
c) Add this 36 to x^2 + 12x + 40, and then subtract it: We get:
x² + 12x + 36 - 36 = 40, or x² + 12x + 36 = 76
We have to add 36, as indicated above, to "complete the square."
Answer:
Average rate of change = 1
Step-by-step explanation:
Average rate of change of a function between x = a and x = b is defined by,
Average rate of change = 
We have to find the average rate of change of the function in the interval 2 ≤ x ≤ 4
Therefore, average rate of change of the function = 
From the graph attached,
f(4) = 4
f(2) = 2
Average rate of change = 
= 1
Therefore, average rate of change of the function in the given interval is 1.
What is 20% divided by 200?
20% ÷ 200 = ?
20% ÷ 200 = 0.001
20% divided by 200 is 0.001.
