Answer:

Perimeter would be 12 because you add 2a+2b

Step-by-step explanation:

Since perimeter is adding all the sides you have to add 4+4+2+2

Answer:

Step-by-step explanation: A=4, b=2

Top side 3b this means 3(2)=6

The bottom side measurement is the same 6

The left side 3a - b means 3(4) - 2 = 10

The right side measurement is the same as the left 10

Don't forget is a rectangle ( In a rectangle, all the angles are the same, and the opposite sides are the same length and are also parallel.)

The perimeter is the sum of all sides:

Therefore, 6 + 6 + 10 + 10 =32

Hope this help!

A bag contains 42 red marbles, 6 white marbles, and 8 gray marbles. You randomly pick out a marble, record its color, and put it

Elanso [62]

For any single draw,

$\mathbb P(\text{white})=\dfrac6{42+6+8}=\dfrac6{56}$
$\mathbb P(\text{gray})=\dfrac8{42+6+8}=\dfrac8{56}$

Drawing a white marble or a gray marble are disjoint events; only one of them can happen. So

$\mathbb P(\text{white or gray})=\mathbb P(\text{white})+\mathbb P(\text{gray})-\underbrace{\mathbb P(\text{white and gray})}_0$
$\mathbb P(\text{white or gray})=\dfrac6{56}+\dfrac8{56}=\dfrac{14}{56}$

Out of 224 draws, you should expect $\dfrac{14}{56}\times224=56$ of the marbles to be either white or gray.
