Answer:
Perimeter of rectangle = 14x - 2
Area of rectangle = 10x² + x - 2
Step-by-step explanation:
<u>Finding the perimeter of the rectangle:</u>
⇒ Perimeter of rectangle = 2(L) + 2(B)
⇒ Perimeter of rectangle = 2(2x + 1) + 2(5x - 2)
⇒ Perimeter of rectangle = 4x + 2 + 10x - 4
⇒ Perimeter of rectangle = 14x - 2
<u>Finding the area of the rectangle:</u>
Area of rectangle = LB
⇒ Area of rectangle = (2x + 1)(5x - 2)
⇒ Area of rectangle = 10x² - 4x + 5x - 2
⇒ Area of rectangle = 10x² + x - 2
The ratio of male fishes to female fishes is 3 : 2
<u>Solution:</u>
Given, male punky fish = 9 stripes
Female punky fish = 8 stripes.
Total stripes = 86
<em><u>Finding the ratio of male fish to female fish:</u></em>
Let the number of male fishes be "m", and the number of female fishes be "n"
The, given that, total strips = 86
which means, total male strips + total female stripes = 86


The only values that can satisfy above equation are m = 6 and n = 4
Now, ratio of male fishes to female fishes = m : n = 6 : 4 = 3 : 2
Hence, the ratio of male fishes to female fishes is found out as 3 : 2
Answer:

Step-by-step explanation:
Both angles labeled, are actually <u>Supplementary Angles</u> (which two angles that add up to
). So, to find the missing measurement of an angle, which is the angle labeled in
, you need to take
and subtract it from
to get the missing angle measurement:

(angle measurement for the angle labeled in
)
