2x(5+3x)-x find the coefficient of x

Mathematics

s344n2d4d5 [400]3 years ago
4 0

To start, we need to distribute

multiply 2x by <em>everything</em> in the parenthesis

2x (5 + 3x) - x

2x × 5 = 10x

2x × 3x = 6x²

now we have...

10x + 6x² - x

<em>simplify </em>

<u>6x² + 9x </u>

the coefficient of x is 9!

Evelyn has $524.96 in her checking account. She must maintain a $500 balance to avoid a fee. She wrote a check for $32.50 today.
cupoosta [38]

A linear inequality to represent the algebraic expression is given as 492.46 - x ≥ 500

<h3>Linear Inequality</h3>

Linear inequalities are inequalities that involve at least one linear algebraic expression, that is, a polynomial of degree 1 is compared with another algebraic expression of degree less than or equal to 1.

In this problem, her minimum balance must not decrease beyond $500 or she will pay a fee.

where

  • x = withdrawals

The inequality to represent this can be written as

524.96 - 32.50 - x ≥ 500

Simplifying this;

492.46 - x ≥ 500

The linear inequality is 492.46 - x ≥ 500

Please awnser questions, no links, no I dont know
balandron [24]

Answer: C

Step-by-step explanation:

The equation is 3x = 6, that represents 3 x ? = 6, babe. 3 x 2 = 6, so that means C must be the answer. If it was D, it would be 0.2 I think, and if it was B, it would’ve been -2. If it was A, it would’ve been 0. Bye-bye toots~
