This question you are asking is order of operations also know as PEMDAS: please excuse my dear aunt sally is a great way to remember it.

P: parenthesis

E: exponents

M: multiply (From left to right)

> These 2 can be switched. As long as you are going left to right, you do which one comes first.

D: divide (From left to right)

A: add (From left to right)

> These 2 can be switched. As long as you are going left to right, you do which one comes first.

S: subtract (From left to right)

The answer is: 11

Explanation:

If x is 6, then we can start filling things in. Instead of 2(x+1)-3 we can put 2(6+1)-3. Then we do the parenthesis first because of pemdas. we get 6+1= 7. Then we lay it out. 2 (7) -3. 2 times 7 = 14. Last we subtract 3. 14-3= 11. :) That i how we get the answer. Hope this helps :)

What is the difference of the polynomials?(–2x3y2 + 4x2y3 – 3xy4) – (6x4y – 5x2y3 – y5)A–6x4y – 2x3y2 + 9x2y3 – 3xy4 + y5B–6x4y

saul85 [17]

We have to calculate the difference of the given polynomials, we follows as:

$(-2x^{3}y^{2}+4x^{2}y^{3}-3xy^{4})-(6x^{4}y-5x^{2}y^{3}-y^{5})$

After opening the brackets, the signs of all the terms changes as there is negative sign before the bracket.

= $(-2x^{3}y^{2}+4x^{2}y^{3}-3xy^{4})-6x^{4}y+5x^{2}y^{3}+y^{5})$

Combining all the like terms, we get as

= $(-2x^{3}y^{2})+(4x^{2}y^{3}+5x^{2}y^{3})-3xy^{4}-6x^{4}y+y^{5}$

= $-2x^{3}y^{2}+9x^{2}y^{3}-3xy^{4}-6x^{4}y+y^{5}$

Option A is the correct answer.

2. In the product of (4a3 + 5a2 – 11a) and (-15 + 3a – 7a2), the co-efficient of a4 is …………………… .

vekshin1

Answer:

- 23

Step-by-step explanation:

We could do this the long way and expand the whole product or note that the $a^{4}$ terms arise from the product of the a³ and a terms and the product of the a² and a² terms, that is

4a³ × 3a = 12 $a^{4}$

+ 5a² × - 7a² = - 35 $a^{4}$

Summing gives

12 $a^{4}$ - 35 $a^{4}$ = - 23 $a^{4}$

with coefficient - 23

An aquarium is expanding its touch tank exhibit and is going to double the dimensions of the original tank.

tigry1 [53]

If you double the dimensions of the tank, you also double the volume of the tank.
Therefore, volume of the new touch tank = 2000 x 2 = 4000 ft^3

Which is the highest value 4.008,4.08,4.8 or 0.480?

Alex787 [66]

Answer:

4.8

Step-by-step explanation:

Let's see here we know the last one can't be the highest because there is no digit that is to the left of the decimal place, so that is a pure fraction, now we're all left with 4 in the left place, so we compare all the digits, and we find that the third option has 8 tenths, which is in fact greater than 8 hundredths or 8 thousandths.
