Write -2x 2(-5x 2 +4x 3) in standard form

Answers

If you would like to write -2x^2 * (-5x^2 + 4x^3) in standard form, you can do this like this:

Writing the polynomial in standard form means that you have to write the terms by descending degree:
-2x^2 * (-5x^2 + 4x^3) = 2 * 5 * x^2 * x^2 - 2 * 4 * x^2 * x^3 = 10 * x^4 - 8 * x^5 = - 8x^5 + 10x^4

The correct result would be - 8x^5 + 10x^4.

The expression $-2x^2(-5x^2 + 4x^3)$ in standard form is $10x^4 - 8x^5$ .

Given Expression, $-2x^2(-5x^2 + 4x^3)$

Simplify it by expanding the multiplication and combining like terms.

$-2x^2(-5x^2 + 4x^3)$

First, distribute $-2x^2$ to each term inside the parentheses:

$-2x^2 * -5x^2 + (-2x^2) * 4x^3$

$10x^4 - 8x^5$

The expression $-2x^2(-5x^2 + 4x^3)$ in standard form is $10x^4 - 8x^5$ .

Therefore, the standard form is $10x^4 - 8x^5$ .

Option C

Step-by-step explanation:

Lane is 10 times Mels age. If the difference in their age is 27, how old is Mel?

Answers

The answer is 3!

explanation; 3x10 equals 30. the difference is 27 years and 30-3=27!

L = 10M
27 = L - M

27 = 10M - M

27 = 9M

M = 3

L = 10M = 10(3) = 30

Lane is 30 years old
Mel is 3 years old

Whats the least common denominator for 2 ∕3 , 5 ∕6 , and 9 ∕4

Answers

Finding the least common denominator-
What is the smallest number that all denominators can go into? Well I see that the 2/3 has a relation to 5/6. ( 3 * 2 = 6 ).

4 (9/4) does not have a relation to the 6 in 5/6. So, what is the smallest number that 6 and 4 can go into? I see that it is 12. So the answer is 12.
All three numbers, 4, 6, and 3 can go into 12 and 12 is the smallest.

A student earns $7.50 per hour at her part-time job. She wants to earn at least $200.Enter an inequality that represents all of the possible numbers of hours (h) the student could work to meet her goal.

Enter the least whole number of hours the student needs to work in order to earn at least $200

Answers

Answer: 7.50 h ≥200

She needs to work 27 hours to earn at least $200.

Step-by-step explanation:

Hi, to write the inequality we have to analyze the information given:

Earnings per hour : $7.50

Hours : h

She wants to earn at least $200.

So, she earns $7.50 per hour, the expression that represents the statement is $7.50h.

She wants to earn at least $200, "at least" means more or equal (≥200).

Mathematically speaking:

$7.50 h ≥200

This is the inequality that represents all of the possible numbers of hours (h) the student could work to meet her goal.

For the second part we simply solve the inequation:

7.50 h ≥200

h ≥200/7.50

h ≥ 26.67

Rounded to the nearest whole number:

h ≥ 27

She needs to work 27 hours to earn at least $200.

Total amount of cash the student earns per hour is $7.5, let the time taken to earn $200 be h, thus the inequality representing this will be:
7.5h≤200
thus
h≤80/3
writing in whole numbers we shall have:
h≤27
