Answer: 39
Step-by-step explanation:
SInce the problem asks for the expression when a=2 and d=5, you olug in the values of a and d and solve.
(5)²+3(2)+6+(2) [exponent]
25+3(2)+6+2 [multiply]
25+6+6+2 [add]
39
After plugging in a=2 and d=5, we got 39 as our answer.
You mean what is 9/0 simplified to?
Answer: x = 9/4
Step-by-step explanation:
4x+12+2=23
4x+14 = 23
4x = 9
x = 9/4
Answer:
A = choosing a red marble
B = choosing a green marble
Probability of A happening = P(A) = 5/(3+5+4) = 5/12
Probability of B happening = P(B) = 4/(3+5+4) = 4/12
Probability of either happening = P(A) + P(B) = 5/12 + 4/12 = 7/12
The key word in their question is red OR green and that is why we add the two probabilities. If they ask the probability of them both happening (if they said red AND green), you would multiply P(A)*P(B).
