She forgot to distribute the 2 fully.
ie. After the 3 to the 9x.
It should have been,
2(3 + 9x) - 2x
6 + 18x - 2x
6 + 16x

Define the words <br><br> please help
Brrunno [24]

Answer:

Irrational Number: A number that cannot be written as a fraction  

a

b

(where b ≠ 0), a repeating decimal, or a terminating decimal.

Rational Number: A number that can be written as a fraction  

a

b

(where b ≠ 0), a repeating decimal, or a terminating decimal.

Repeating Decimal: A decimal where, when dividing, a digit or group of digits repeats without end in the quotient; there is a pattern in the digits that repeat without end.

Terminating Decimal: A decimal that, when dividing, ends with a remainder of zero.

Perfect cube: A number that is made by cubing a number: a3 = a • a • a.

Perfect square: A number that is made by squaring a number: a2 = a • a.

Cube Root:

if a3 = b, then a = 3√b

For principal square root this was the best I could do: The principle of square roots requires that the square root of the side with the unknown (x) only includes x without any exponent (other than 1). The simplest form that fits this criterion is: but x can also be an expression.

I hope this helps :3

The sum of 4 times a number and -3 added to 9 times the number
Phoenix [80]

Answer:

The sum of 4 times a number and -3 added to 9 times the number is:

4x + (-3 + 9x)

Step-by-step explanation:

Determine what each of the words means

"the sum of" - you are going to be adding the following two numbers.

"4 times a number" - Let x be the number, so, 4x is the first number.

"and -3 added to" - again, it's going to be addition of this number and the following number.

"9 times the number" - let x be the number, so, 9x is the second number in the second addition.

Now that we know what it all means, put it together:

4x + (-3 + 9x)


I really hope this helps you =)
