2 answers:

8 0

Let's look at the two denominators:
7= 7
4= 4
LCM(7,4)= 4*7= 28

5/7+ 1/4
= (5*4)/ (7*4)+ (1*7)/ (4*7)
= 20/28+ 7/28 (common denominator is 28)
= 27/28

The final answer is 27/28~

what is the area and perimeter of the figure with the given vertices? (7,8) , (-5, -8) , (7,-8) , (-5,8)?

MArishka [77]

Answer:

perimeter: 56 units
area: 192 square units

Step-by-step explanation:

We assume you're interested in the convex polygon, so the given vertices are <em>not</em> listed in order around the figure.

The figure is 12 units by 16 units, so has a perimeter of ...

P = 2(L +W)

P = 2(16 +12) = 56 . . . . units

and an area of ...

A = LW

A = (16)(12) = 192 . . . . square units
