Step-by-step explanation: To write 60/80 that has a denominator less than 80, we can write reduce this fraction.
Notice that 60/80 can be reduced because 60 and 80 have a greatest common factor of 20. So we divide both 60 and 80 by 20 to get 3/4. Now, this is an equivalent fraction that has a denominator that's less than 80. Image is provided below.
Answer:
16 : 5
Step-by-step explanation:
For 2 similar polygons with ratio of sides/perimeter = a : b
Then the ratio of areas = a² : b²
Here the ratio of areas = 256 : 325
Hence ratio of perimeters = √256 : √325 = 16 : 5 √13
Length would be 362.5
He width would be 1087.5
Hope this helps :)

(gof)(-3) means the composition of two functions at x = -3.
(gof)(-3) can also be expressed as g(f(-3))
So, first we find f(-3)
f(x) = x² + 5
f(-3) = 9 + 5 = 14
g(f(-3)) = g(14)
g(14) = (14+5)/14 = 19/14
Thus, option C gives the correct answer
