Answer:
If you go by normal method, no. of possible passwords that can be created with 26 alphabets are 26X26X26X26 = 456,976
Step-by-step explanation:
. If you do not want to repeat the alphabets, you can use combinations. i.e. C(26, 4) or 26C4 = 358,800 ways

Answer: 3x2 + 3x - 7
Step-by-step explanation: The first term is, 3x2 its coefficient is 3
The middle term is, +3x its coefficient is 3
The last term, the constant, is -7
1.Multiply the coefficient of the first term by the constant 3 times -7 = -21
2. Find two factors of -21 whose sum equals the coefficient of the middle term, which is 3
Answer/Step-by-step explanation:
1. The figure is composed of a triangle and a rectangle.
Area of the triangle = ½*base*height
base = 4 ft
height = 12 - 8 = 4ft
Area of triangle = ½*4*4 = 8 ft²
Area of rectangle = length * width
Length = 8 ft
Width = 4 ft
Area of rectangle = 8*4 = 32 ft²
✔️Area of the figure = 8 + 32 = 40 ft²
2. The figure is composed of a semicircle and a triangle
Area of the semicircle = ½(πr²)
radius (r) = 3 cm
π = 3
Area = ½(3*3²) = 13.5 cm²
Area of triangle = ½*base*height
base = 3*2 = 6 cm
height = 6 cm
Area = ½*6*6 = 6 cm²
✔️Area of the figure = 13.5 + 6 = 19.5 cm²
X is 16 so turn everything into a equation
