Write in a standard form 2750000

In the instructions for this problem I am told to distribute -4x^2. Why?
the order of operations is the order in which to simlify
if you look inside the parenthases, all like terms have been combined so the inside of parenthasees have already been simlified
expanding the exponents won't make it any easier so we move to distriubiting (or mulitplying)
so then the next step is mulitply -4x^2 by the trinomial

<span>In the order of operations you must do problems inside parentheses first. Why does multiplying monomials by polynomials change this? </span>multiplying monomails by polynomials does not change this

<span>Would the answer come out different if I did the work according to the order of operations?
no because distributing first is what you should do if you follow order of operations

I need to do all of them.

uh, solve for x? Its simple, but first, since it is a prep for a test, you should study how to solve for x, which is easy. So To solve for x, bring the variable to one side, and bring all the remaining values to the other side by applying arithmetic operations on both sides of the equation. Simplify the values to find the result.

Let’s start with a simple equation as, x + 2 = 7

How do you get x by itself?

Subtract 2 from both sides

⇒ x + 2 - 2 = 7 - 2

⇒ x = 5

Now, check the answer, x = 5 by substituting it back into the equation. We get 5 + 2= 7.

L.H.S = R.H.S

And then for a triangle:

Solve for x" the unknown side or angle in atriangle we can use properties of triangle or thePythagorean theorem.

Let us understand solve for x in a triangle with the help of an example.

△ ABC is right-angled at B with two of its legs measuring 7 units and 24 units. Find the hypotenuse x.

then in △ABC by using the Pythagorean theorem,

we get AC2 = AB2 + BC2

⇒ x2 = 72 + 242

⇒ x2 = 49 + 576

⇒ x2 = 625

⇒ x = √625

⇒ x = 25 units

get it? Good

Answer: you didnt add a question or possible answer choices so nobody can answer this question

Step-by-step explanation:

Divide the ones column dividend by the divisor.

Multiply the divisor by the quotient in the right place column.

Subtract the product from the ones column.
