I believe the answer is A.
Absolute value best proves my answer.
Absolute value is how far a number is from zero.
Ok. So, if 8 pens cost £12. Then we would divide £12 by 8. Each pen costs £1.5.
So now we are going to multiply £1.5 and 10. £1.5*10=15.
The total of 10 pens is £15.
I hope this helps, if you need any additional help, just ask. I am here to help you as needed.
The answer is D. 64. Have a nice day!
59.4cm
Use Pythagorean theorem to find the diagonal (^ means exponent)
a^2 + b^2 = c^2
42^2 + 42^2= c^2
1764+1764=c^2
3528=c^2
square root both sides
c= 59.39696962
round and you get 59.4 cm
