2. A coin purse contains d dimes and q quarters. There are 20 coins in the purse, and the total value of the coins is $4.25. Which system of equations represents this situation?
A {d + q = 4.25
{0.1d + 0.25q = 20
B {d + q = 20
{0.1d + 0.25q = 4.25
C {d + q = 20
{d + q = 4.25
Complete the pattern: 2×4=8 20×4=80 200×4=800 2000×4=
Which comparison of the two equations is accurate?
Equation A: Sqrt x^2 + 3x-6 - Sqrt X+2
Equation B: Sqrt x^2 + 3x-6 = Sqrt x+2
O Both equations have different solutions because the square root of a number is not the same as the cube root of a
number
O Both equations result in different equations after eliminating the radicals, so they have the different solutions.
O Both equations have the same potential solutions, but equation A might have extraneous solutions.
Both equations have the same potential solutions, but equation B might have extraneous solutions.
Answer: C, Both equations have the same potential solutions, but equation A might have extraneous solutions.
Step-by-step explanation:

A fair con is tossed 80 times in an experiment. If the coin is fair, what would be a reasonable number of times tails should appear
based on your knowledge of the theoretical probability of this event?
Answer: 40 would be a reasonable number of times tails should appear if the coin is fair. Fair means 50/50 chance.
So, divide 80 by 2. 80/2 = 40.

Find the area in the pic please!!
Answer:
Area = 970 ft²
Step-by-step explanation:
The shape is composed of a square and a triangle.
Therefore:
Area of the shape = area of square + area of triangle
✔️Area of square = s²
s = 20 ft
Area = 20²
Area of square = 400 ft²
✔️Area of triangle = ½*b*h
b = 20 + 9 + 9 = 38 ft
h = 30 ft
Area of triangle = ½*38*30 = 570 ft²
✅Area of the shape = 400 + 570 = 970 ft²
