Answer:

the answer to this would be 256.

Step-by-step explanation:

before explaining this,

- negative x negative = positive

- positive x positive = positive

- negative x positive = negative

- positive x negative = negative

this would be because -2 x -2 it equals 4. then, we multiply 4 x -2 and we get -8, then we multiply -8 x -2 and we get 16, then we keep doing the same thing until we get the answer/ used all the -2's.

1. -2 x -2 = 4

2. 4 x -2 = -8

3. -8 x -2 = 16

4. 16 x -2 = -32

5. -32 x -2 = 64

6. 64 x -2 = -128

7. -128 x -2 = 256

Answer:

x = 2

Step-by-step explanation:

1. distribute 9 in 9(x+1)

9x + 9 = 25 + x

2. subtract x from the right side to isolate x onto one side

8x + 9 = 25

3. subtract 9 from the left side

8x = 16

4. divide both sides by 8 to get x alone

x = 2

A card is picked from a standard deck of 52 cards. Determine the odds against and the odds in favor of selecting a red face card

timama [110]

<h3>The probability of picking a red face card from the deck is $(\frac{3}{26} )$ </h3><h3>The probability of NOT picking a red face card from the deck is $(\frac{23}{26} )$ </h3>

Step-by-step explanation:

The total number of cards in the deck = 52

The total number of red( Diamond + Hearts) face cards in the given deck

= 2 Red Queens + 2 Red jacks + 2 Red kings = 6 cards

Let E : Event of picking a red face card from the deck

Now , P( any event) = $\frac{\textrm{The number of favorable observations}}{\textrm{Total number of observations}}$

So, here P(Picking a red face card) = $\frac{\textrm{The number of red face cards}}{\textrm{Total number of cards}} = (\frac{6}{52} ) = (\frac{3}{26})$

Hence, the probability of picking a red face card from the deck is $(\frac{3}{26} )$

Now, as we know P (any event NOT A) = 1 - P(any event A)

So, P(NOT Picking a red face card) = 1 - P(Picking a red face card)

$= 1 - (\frac{3}{26} ) = \frac{26-3}{26} = (\frac{23}{26})$

Hence, the probability of NOT picking a red face card from the deck is $(\frac{23}{26} )$

Lines m and n are parallel. find the value of x.<br> A. 15<br> B. 20<br> C. 65<br> D. 115

torisob [31]

Answer:

Option B, x = 20

Step-by-step explanation:

<u>Step 1: Make an equation</u>

The values of 65 degrees and (3x + 5) are equal.

65 = 3x + 5

<u>Step 2: Subtract 5 from both sides</u>

65 - 5 = 3x + 5 - 5

60 = 3x

<u>Step 3: Divide both sides by 3</u>

60 / 3 = 3x / 3

<em />

Answer: Option B, x = 20
