40%= 2/5 so, 70×2/5= 14 ×2.
so the expression is= (14)(2) which is 28!
thanks
:D

The answer is 12 because the lines of the parrellel shape he’ll come across each other
Answer:
51m
Step-by-step explanation:
For this equation, you want to use pythagoras' theorem (or pythagorean theorem) to work out the hypotenuse (diagonal line)
The formula for this is a²+b²=c², where c is the hypotenuse.
We can sub in the 2 sides for a and b, turning the equation into 24²+45²=c².
Working out the squares gives 576+2025=c², which can be solved to c²=2601.
To get c, we must square root both sides, which results in c=51m.
**This question involves pythagoras' theorem, which you may wish to revise. I'm always happy to help!
