Answer:
3/ 10
Step-by-step explanation:
Count of numbers up to 50 = 50
Prime numbers up to 50 :
{2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47}
Count of prime numbers up to 50 = 15
Hence, ratio of prime numbers to all numbers ;
15 : 50
3 / 10
48? i guess. i hope this helps u out with ur question
length of square = 18
x = side of square
x-7 = side of triangle
3(x-7) + 39 = 4x
3x-21 + 39 = 4x
3x+18 = 4x
18=x
square 18x4 =72(perimeter square)
triangle side (18-7=11)
11x3 = 33(perimeter triangle)
72-33=39
(x+4)²-3
x x=x²
4 4 =8
then +3
but a plus and a minus makes a minus so it would be -3
