let length of the rectangle be l

length is 6 cm longer than the width, w

l = w + 6

perimeter of rectangle is 72 cm

= 2l + 2w

substitute l = w + 6

2(w+6) + 2w = 72

4w + 12 = 72

4w = 60

x = 15

ans is C. 15 cm

Answer:

Step-by-step explanation:

Perimeter = 2 x (length + width)

72 = 2 x ( l + w)

Because l = w +6

72 = 2 x (w + 6 + w)

= 2 x (2w + 6)

= 4w + 12

4w = 60

w = 15 cm

The answer is C.

Use the Side-Splitter Theorem to find x, given that PQ||BC . The figure is not drawn to scale.

MrRa [10]

Answer: x=12

Step-by-step explanation:

1. Accoding to the Side-Splitter Theorem, if a line interesect two sides of the triangle and it is parallel to the third side, then the other two sides are divided by the line proportionally.

2. Then, you can form the following proportion:

$\frac{PA}{BP}=\frac{QA}{CQ}$

3. Substitute values and solve for x:

$\frac{8}{x}=\frac{12}{18}\\18*8=12x\\x=12$
