Use the order of operations to find the value of the expression five times two plus six minus five

=11 *The answer should be the positive sign.*

Step-by-step explanation:

You had to used stands for P-parenthesis, E-exponents, M-multiply, D-divide, A-add, and S-subtract. It can also go left to right. First, calculate multiply. This gives us 5*2=10. Then rewrite the problem. This gives us 10+6-5. Add and subtract left to right. This gives us 10+6=16-5=11. This gives us the final answer is 16-5=11.

Hope this helps!

Thanks!

Have a great day!

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
