Answer:
Only the isosceles trapezoid has an area of 32 cm².
Step-by-step explanation:
Let's calculate the area of each polygon.
For the two triangles we have:
This polygon does not have an area of 32 cm².
For the rectangle we have:
This polygon does not have an area of 32 cm².
For the rectangle trapezoid we have:
So, this polygon does not have an area of 32 cm².
Finally, for the isosceles trapezoid:
This polygon does have an area of 32 cm².
Therefore, only the isosceles trapezoid has an area of 32 cm².

3x-6+4=-20
- add 6 to both sides
3x+4=-20 +6
3x+4=-14
- then subtract 4 from both sides
3x=-14 - 4
3x=-18
- then divide 3 from both sides
-18 divided by 3 = -6
x= -6
Rectangles are similar figures, thus if scaled copies of each other then the ratios of corresponding sides must be equal
compare ratios of lengths and widths
rectangles A and B
k = 
= 
← ratio of lengths
k = 
= ← ratio of widths
scale factors are equivalent, hence rectangle A is a scaled copy of B
rectangles C and B
k = 
= 
← ratio of lengths
k = 
= 
← ratio of width
scale factors (k ) are not equal, hence C is not a scaled copy of B
rectangles A and C
k = 
= 
← ratio of lengths
k = 
← ratio of widths
the scale factors are not equal hence A is not a scaled copy of C
Answer:
10.92
Step-by-step explanation:
turn the percent into a decimal, .28
.28×39=10.92
59= 3x +2
57=3x
19=x
Which means she has 19 friends.
