Length - l
Width - w
Given,
Perimeter = 60 
2(l +w) = 60
l + w = 30 
l = 30 - w
Given,
l = 3w
30 - w = 3w
4w = 30
--- w = 7.5
--- l = 3w = 3 * 7.5 = 29.5
Hence, the length of the rectangle is 29.5 and the width is 7.5

Answer:
70
Step-by-step explanation:
100 - 2(x + 5) = 100 - 2x - 10 = 90 -2x
90 - 2x
90 - 2×10
90 - 20 = 70
 
        
                    
             
        
        
        
hey there
the answer is
14x + 6 = 5x + -3
6 + 14x = 5x + -5
6 + 14x = -3 + 5x
6 + 14x + -5x = -3 + 5x + -5x
Combine like terms: 14x + -5x = 9x
6 + 9x = -3 + 5x + -5x
Combine like terms: 5x + -5x = 0
6 + 9x = -3 + 0
6 + 9x = -3
6 + -6 + 9x = -3 + -6
Combine like terms: 6 + -6 = 0
0 + 9x = -3 + -6
9x = -3 + -6
Combine like terms: -3 + -6 = -9
9x = -9
Divide each side by '9'.
x = -1
Simplifying
x = -1
