Simplify the expression 3a+5b+2c+8b by combining like terms

3a+13b+2c

Step-by-step explanation:

Like terms are terms with the same variable, which in this case is 5b and 8b.

Using the distributive property,

5b+8b=(5+8)b=13b

Since there are no other like terms, all you have to do is use 13b in the expression instead of 5b and 8b, and you end up with

3a+13b+2c

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
