Answer:
Area = 53 in²
Step-by-step explanation:
area of a box = 8 * 6 = 48 in²
area of a triangle = 1/2 * b * h
b = 6 - 4 = 2 in
h = 13 - 8 = 5 in
area of a triangle = 1/2 * 2 * 5 = 5 in²
total area = area of a triangle + area of a box
total area = 5 in² + 48 in²
total area = 53 in²
Answer: B. |x-100| = 25
Explanation:
Draw out a number line. Mark 75, 100 and 125 on the number line as points A, B, and C in that order. Don't worry about the spacing.
The value of x represents where the train is. So if we had say x = 85, then it would be at location 85 on the number line. Writing |x-100| is the distance from x to 100. The absolute value ensures the distance is never negative. We want this distance to be 25 because after traveling 25 cm, the switch is turned, and the train goes the other way.

Answer:
x = 1, x = -1
Step-by-step explanation:
x^2 - 3x - 1 = -3x
Simplify...
x^2 - 3x - 1 + 3x = 0
x^2 - 1 = 0
Use this formula to factor: (a-b)(a+b) = a^2 - b^2
So x^2 - 1 will factor to...
(x-1)(x+1)
Solve for the equation: (x-1)(x+1) = 0
x - 1 =0
x = 1
x + 1 = 0
x = -1
