Step-by-step explanation:
14.50 - 4.25 - 5.15 = 5.10
Answer: <u><em>x=8</em></u>
Step-by-step explanation:
Simplifying
3(x + -2) = 18
Reorder the terms:
3(-2 + x) = 18
(-2 * 3 + x * 3) = 18
(-6 + 3x) = 18
Solving
-6 + 3x = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + 3x = 18 + 6
Combine like terms: -6 + 6 = 0
0 + 3x = 18 + 6
3x = 18 + 6
Combine like terms: 18 + 6 = 24
3x = 24
Divide each side by '3'.
x = 8
Simplifying
x = 8
1. X=5
2. I think I’m not sure is - 5.04

2.49 * 10
Answer:
12 ft
Step-by-step explanation:
we know the areas of the 2 top squares.
the area of a square is simply the square of its side length.
=>
81 ft² means side length is 9 ft.
225 ft² means side length is 15 ft.
these are also 2 of the sides of the right triangle.
the third side we get by using Pythagoras :
c² = a² + b²
with c being the side opposite of the 90 degree angle.
so,
225 = 81 + x²
as x is also the third side of the triangle.
=> 144 = x²
x = 12 ft
