Answer:
4
Step-by-step explanation:
How many times does the denominator go into the numerator, in this case 10 goes into 40 4 times.
3 + 3 + 3 + 3 + 5 + 5 = 22
the perimeter is 22 cm
6 - 5x
the number isn't specific so u'll need to use a variable for it
u're multiplying that number by 5 so u'll write it as 5x
and ur subtracting it from 6
