The length of a rectangle is 3 more than twice its width, w. Which expression represents the area of this rectangle, and what is the area if the width is 5 cm? w(2 + 3w): 85 cm?
w(3 + 2w): 65 cm
2w(w + 3): 80 cm2
(w + 2)(3w): 105 cm2

Step-by-step explanation:

Let width be w.

Let the length equal 3+2w.

Since w=5 cm,

3+2w=13 cm

Area of rectangle= length× width

Area=13×5

Area=65 cm2

So the answer is the 2nd option. Hope it helps!

8x+8> 7x+14

8x-7x> 14-8

x> 6

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
