Step-by-step explanation:

$\frac{2a}{a + b - c} = \frac{2b}{b + c - a} = \frac{2c}{a + c - b} = k \\ \\ by \: theorem \: on \: equal \: ratios \\ \\ \frac{2a + 2b + 2c}{a + b - c + b + c - a + a + c - b} = k \\ \\ \frac{2(a + b + c)}{a + b + c} = k \\ \\ \therefore \: k = 2$

Answer:

see explanation

Step-by-step explanation:

the perimeter (P) is the sum of the 4 sides

(a)

P = a + b + c + d

= x + 7 + 2x + 2 + 8x + x + 10 ← collect like terms

= 12x + 19

(b)

If x = 4 , then

P = 12x + 19 = 12(4) + 19 = 48 + 19 = 67

(c)

If x = 2 , then

P = 12x + 19 = 12(2) + 19 = 24 + 19 = 43

(d)

P = a + b + c + d

= x² + 4x + 8 + 2x² + x ← collect like terms

= 3x² + 5x + 8
