Expand And Simplify (x-2)(2x+4)
Answer 2

Answer:

2x² - 8

Step-by-step explanation:

Given

(x - 2)(2x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

x(2x + 4) - 2(2x + 4) ← distribute both parenthesis

= 2x² + 4x - 4x - 8 ← collect like terms

= 2x² - 8

Answer:

the answer is x= 5 and y = 1.5

Answer :Value of x is 5 Value of y is 1.5Explaination :

Here we have been given with two equations and we will solve them by elimination by substitution method inorder to get the value of x and y.

5x - 4y = 19 (Equation No 1)x + 2y = 8 (Equation No 2)

From Equation No 2 :-

>> x + 2y = 8

>> x = 8 - 2y

In Equation No 1 :-

Substituting here the value of x which we got above as (8 - 2y).

>> 5x - 4y = 19

>> 5 (8 - 2y) - 4y = 19

>> 40 - 10y - 4y = 19

>> 40 - 14y = 19

>> -14y = 19 - 40

>> -14y = -21

>> 14y = 21

>> y = 21 / 14

>> y = 1.5

Finding out value of x :-

>> x = 8 - 2y

>> x = 8 - 2 (1.5)

>> x = 8 - 2 × 1.5

>> x = 8 - 3

>> x = 5

Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month. Write and solve an equation that can be used to determine gg, the number of gigabytes of data Sofia can use while staying within her budget.

Answers

Answer:

To stay within budget, she must use 4.5 gigabytes.

Step-by-step explanation:

Giving the following information:

Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month.

First, we need to establish the total cost formula:

Total cost= 58.5 + 4*x

x= number of gigabytes

Now, we isolate x:

76.5= 58.5 + 4x

18/4= x

4.5= x

To stay within budget, she must use 4.5 gigabytes.

You began operating a small general electric contracting company two years ago. Originally, it was just you and your cousin, but it has grown to five licensed electricians, plus one office manager who takes calls from customers, schedules the work, and orders parts and supplies. Your company handles a wide range of work, including installing new circuit breaker panels, rewiring existing electrical systems for renovations and additions, and installing residential light fixtures, security lighting systems, swimming pool lighting, and ceiling fans. Business has really taken off, and your current manual systems and procedures can no longer keep pace. The office manager has been exploring several options and has identified three different software packages designed for small contractors. Each one of the packages includes software designed for managing parts and supplies inventory, scheduling jobs, and invoicing customers. One of the packages also provides the capability to perform accounts receivable and accounts payable functions. Two of the software packages are from large, well-known companies, and both have an initial licensing cost of roughly $550 plus $100 per year for software support. The other software package is open-source software, with no initial cost and no support cost. The office manager is unsure how to proceed, but has your agreement to spend up to $1000 on new software.Which one of the following should be your next step?a. Define the basic business functions that you need the software to be able perform.b. Determine the date by which you need the new software installed and operational.c.
