Answer:
Solution for 2(x-5)-8=20 equation:
Simplifying
2(x + -5) + -8 = 20
Reorder the terms:
2(-5 + x) + -8 = 20
(-5 * 2 + x * 2) + -8 = 20
(-10 + 2x) + -8 = 20
Reorder the terms:
-10 + -8 + 2x = 20
Combine like terms: -10 + -8 = -18
-18 + 2x = 20
Solving
-18 + 2x = 20
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 2x = 20 + 18
Combine like terms: -18 + 18 = 0
0 + 2x = 20 + 18
2x = 20 + 18
Combine like terms: 20 + 18 = 38
2x = 38
Divide each side by '2'.
x = 19
Simplifying
x = 19
Hello!
The problem has asked that we simplify the given expression using the Distributive Property. The Distributive Property states the following:
a(b + c) = ab + ac
a(b – c) = ab – ac
In this case, we’ll use the second of the two formulas listed above. Let’s begin by inserting any known values given in the original problem:
a(b – c) = ab – ac
5(2x – 5) = 5(2x) – 5(5)
Now simplify the right side of the equation:
5(2x) – 5(5) = 10x – 25
We have now proven that 5(2x – 5) is equal to 10x – 25. Therefore, the correct answer is C.
I hope this helps!
Answer:
its either -10 or 0
Step-by-step explanation:
If the sides are in the ratio of 5:3 then the area will increase by a factor of:(5 / 3) ^2

Area of small hexagon = 81
Area of larger hexagon = 81 * 2.777777777
Area of larger hexagon = 225 square meters
The correct answer for that question is 280
