Answer:

(x - 26)(x + 14)

Step-by-step explanation:

We need to find 2 numbers that add up to -12 and multiply to -364.

We know we will need one positive number and one negative number:

-26 and 14 work to multiply to -364.

-26 and 14 add up to -12.

∴ (x - 26)(x + 14)

At a baseball game, 3 drinks and 4 hotdogs cost $15.00. At the same game, 3 drinks and 1 hotdog cost $10.50. Find the cost for a

Serhud [2]

Answer:

Step-by-step explanation:

Given data

Let the cost of drinks be x

and the cost of hotdogs be y

3x+4y=15-------1

also

3x+y= 10.5------2

solve 1 and 2

3x+4y=15

-3x+y= 10.5

3y= 4.5

divide both sides by 3

y= 4.5/3

y= $1.5

Put y= 1.5 in 1

3x+4(1.5)=15

3x+6= 15

3x=15-6

3x= 9

x= 9/3

x= $3

Hence the cost of a drink is $3

6x + 2y = 12 solve for y

RUDIKE [14]

Subtract 6x from both sides to get:

2y=-6x+12

Then divide both sides by 2 to get:

y=-3x+6

I need help on this question I’m confused I think a &b are the same and c &d are different but I’m not to sure !

Nina [5.8K]

<h3>Answer: They're all the same</h3>

====================================================

Reason:

$2^6$ means we have 6 copies of "2" multiplied out as shown in choice B. That explains how A and B are the same, and we can say

$2^6 = (2*2*2)*(2*2*2)$

The parenthesis are optional, but I find they're handy to count the '2's easier.

----------------

Now notice that

$2^3 = 2*2*2$

So,

$2^6 = (2*2*2)*(2*2*2)\\\\2^6 = (2^3)*(2^3)\\\\2^6 = (2^3)^2\\\\$

The last step is possible because we have two copies of $2^3$ multiplied together.

This shows that choice C is equivalent to A and B.

-------------------

Lastly,

$2^6 = (2*2*2)*(2*2*2)\\\\2^6 = (2*2)*(2*2)*(2*2)\\\\2^6 = (2^2)*(2^2)*(2^2)\\\\2^6 = (2^2)^3\\\\$

The jump to the last step is possible because we have three copies of $2^2$ multiplied together.

This shows choice D is equivalent to the others.

All four expressions are the same.

They represent different ways to say the same number. That number being 64.
