Answer:He has 74 baseball cards

Step-by-step explanation:

He has 38 baseball cards left, and since his dog ate half of it he must have had double the amount of cards. So 38 + 38 . This equals to 74.

Which algebraic expression is a polynomial with a degree of 2? 4x3 − 2x 10x2 − StartRoot x EndRoot 8x3+ StartFraction 5 Over x E
kati45 [8]

Answer:

6x^2 - 6x + 5

Step-by-step explanation:

Given

List of Options

Required

Which of the options has a degree of 2

The general format of a polynomial is

ax^n + bx^{n-1} + ..... + cx^{n-n}

<em>Where n represents the degree </em>

In this case;

n = 2

Substitute 2 for n in expression above;

ax^n + bx^{n-1} + ..... + cx^{n-n}

ax^2 + bx^{2-1} + ..... + cx^{2-2}

ax^2 + bx^{1} + ..... + cx^{0}

ax^2 + bx + c *1

ax^2 + bx + c

Comparing this format to the list of given options; the option with the same format is: 6x^2 - 6x + 5

Where a = 6; b = -6 and c = 5

<em>Hence, the polynomial with a degree of 2 is </em>6x^2 - 6x + 5

Can someone help me please 
gayaneshka [121]
Wow !  If I understand what's go0ing on here, then
we have to be careful, and THINK .

I was going to ask you "What does  Ф  mean ?", and then I realized,
Ф is a new operation that the teacher invented.

The first line on the board is the definition of Ф .

Ф means "<u>Add the two numbers and subtract 4</u>."

Now you have to use this new invention to find the value
of the second line:

Take care of the stuff inside the parentheses first: ( 4 Ф 2 )
<u>Add the two numbers and subtract 4
</u>4 + 2 - 4 = <u>2</u><u>
</u>That's the part inside the parentheses. It's <span><u>2</u> .</span><u>

</u>NOW, we have to do the new operation with the 2 inside,
and the 3 that's outside the parentheses:<u>

</u>3 Ф 2
<u>Add the two numbers and subtract 4</u>
3 + 2 - 4 =<u> 1</u>

And that's the final value of 3 Ф (4 Ф 2) .  It's <u>1</u> .

Pretty sneaky.

Which ratio is not equivalent to 15/18?<br> A: 25/30<br> B: 90/105<br> C: 60/72<br> D: 35/42
professor190 [17]

Answer:

B

Step-by-step explanation:

Both of the two numbers should equal the same amount when dividing.

For example, in A

25÷15=1.666...

30÷18=1.666...

Both of these answers are the same so that means that 25/30 is equivalent to 15/18

When you're dividing B though, they don't equal the same amount

90÷15=6

105÷18= 5.833...

that means that 90/105 does NOT equal 15/18

good luck
