1.)

2x^2 + 16x + 32 =

= 2(x^2 + 8x + 16) =

= 2(x + 4)^2

**Answer:**

Option a is correct

**Step-by-step explanation:**

**11x² - 4x = 1**

**Rewriting the equation:**

**11x² - 4x - 1 = 0**

from above equation, a = 11, b = -4, c = -1

As we are asked to solve it with quadratic equation:

put values of a, b and c

taking 2 common above and cutting it with denominator

P = 2l + 2w

p-2w = 2l

p-2w/2 = l

Substitute the perimeter and you should be able to work it out

35x=245

so you would divide both sides by 35

x=7

so it would take her 7 weeks or 1 month and 3 weeks to pay her friend back
