Answer:
20 feet wide, 24 feet long
Step-by-step explanation:
Let x - width, y - length.
The perimeter is given by the formula:
P = 2*(width + length) or using x, y
P = 2*(x + y) = 88
x + y = 44
And we know that the ratio between the sides is 5/6:
x/y = 5/6. x is on top because the length is bigger than the width
x = 5y/6
Plug this in the first expression:
y + 5y/6 = 44. Muliply by 6
6y + 5y = 264
11y = 264
y = 264/11 = 24.
So x = 5(24)/6  = 20

Answer:
- 48°
- 60°
- 72°
Step-by-step explanation:
The sum of ratio units is 4+5+6 = 15, so each unit stands for 180°/15 = 12°. Multiplying the ratio units by 12° gives the angle values:
   4×12° : 5×12° : 6×12° = 48° : 60° : 72°
Angles 1 to 3 are 48°, 60°, 72°, respectively.
 
        
             
        
        
        
Since the first term is -5 and the difference is 6 so a2=1,a3=7,a4=13,a5=19. Hope that helped. if you have any questions regarding how I got the values, feel free to ask. :')
        
             
        
        
        
Answer:
Step-by-step explanation:
x² + 9x + 18 = x² + 6x + 3x + 18
                    = x(x + 6) + 3(x + 6)
                    = (x + 3)(x + 6)
x² + 16x + 63 = x² + 9x + 7x + 63
                      = x(x + 9) + 7( x+ 9)
                      = (x + 7)(x + 9)
y² + 13y + 36 = y²+ 9y + 4y + 36
                      = y(y + 9) + 4(y + 9)
                      = (y + 4)(y + 9)
(a). Factored form of the expression (y² + 13y + 36) is (y + 4)(y + 9).
Therefore, Lyndsey's answer is wrong.
(b). Factors are (y + 4) and (y + 9).
(c). Factored form of the expression should be (y + 4)(y + 9) instead of Lindsey's answer (y + 6)(y + 6).
