There are 120 ways to color the 4 rectangles
<h3>How to determine the number of ways?</h3>
The given parameters are:
Paints, n = 5
Rectangles, = 4
The number of ways to color the rectangles is
This gives
Apply the permutation formula
Evaluate the expression
Ways = 120
Hence, there are 120 ways to color the 4 rectangles

Answer:
y = 4
x = -6
Step-by-step explanation:
multiply first equation by 3
3×(5x+4y)= -14 ➡ 15x + 12y = -42
multiply second equation by -5
-5×(3x+6y)= 6➡ -15x -30y = -30
now add both equations up
15x +12y -15x -30y = -42 -30 (15x will eliminate -15x)
-18y = -72
y = 4 use this to find value of x
3x + 6×4 = 6 ➡ ex = -18 ➡ x = -6
Answer:
78.5 cm
Step-by-step explanation:
The area of a circle is represented by A = πr². Since we are replacing the value of pi(π) with 3.14, and the diameter is 10, meaning the radius(r) is 5, we can plug both values into the equation, to get A = 3.14(5^2). This simplifies to 78.5.
Answer:
Step-by-step explanation:
multiply x as a negative.
Example:
f(x) = 3x + 1
f(-x) = -1(3x) + 1
f(-x) = -3x + 1
