What is the value of the expressionwhen a = 5 and b =2? 2a + b - 3 a. 6 b. 24 c. 9 d. 11

Put the numbers where the corresponding variables are and do the arithmetic.

... 2(5) +(2) -3

... = 10 + 2 - 3

... = 12 - 3

... = 9

The appropriate choice is ...

... C. 9

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
