Question

Exam: Final

Answer 1

Answer:

D)

$6x - 4$

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

where,

Length = 2x - 3; width = x + 1

Thus,

$p = 2(2x - 3 + x + 1)$

Collect like terms in the bracket

$p = 2(2x + x - 3 + 1)$

$p = 2(3x - 2)$

Expand the bracket

$p = 6x - 4$

Answer 2

Answer:

D. 6x-4

Step-by-step explanation:

Since the perimeter of rectangle is;

2 [length + width]

length = (2x - 3)

width = (x + 1)

2 [(2x - 3) + (x + 1)]

4x - 6 + 2x + 2

6x - 4
