Answer:

A White Marble

Step-by-step explanation:

The chance of choosing a white marble is 7/12 (amount of red marbles = 2 because there is no exact number, the problem only states there are more than one marble. To find probability, add all of the possible changes combinations of choosing a marble from the bag. ( 3 + 7 + 2 = twelve. After finding how many possible combinations there are, subtract the # of possible combinations from the # of marbles that are not white. ( 12 - 5 = 7 ). Finally, put the amour of white marbles next to the # of possible combinations. (7/12)

H(x)=(x+5)^2 if we solve h(x)=36

Ivan

Answer:

x = - 11

Step-by-step explanation:

Solving

(x + 5)² = 36 ( take square root of both sides )

x + 5 = ± $\sqrt{36}$ = ± 6 ( subtract 5 from both sides )

x = - 5 ± 6

Then

x = - 5 + 6 = 1

x = - 5 - 6 = - 11

The other solution is x = - 11

Find two consecutive even integers such that twice the second is the same as 186 less than the first integer.

Alisiya [41]

Step-by-step explanation:

let the 2 integers be x and x + 1

2(x + 1) + 186 = x

2x + 188 = x

x = -188

therefore the 2 integers are -188 and -187

5 x 6 = 30

30 + 8.3 = 38.3
