Get all the n together so 3n+2n=5n
5n-17=38
Minus 17 from both sides
5n= 55
N= 11

First you +17 to both sides to get 3n+2n=55
then you do 3n+2n= 5n
so you have 5n=55
so then n=11

Simplify (2x-3)(2x-2)
tensa zangetsu [6.8K]

Answer:

We get the final answer of -4x + 6

Step-by-step explanation:

Let's simplify step-by-step.

2x −3(2x−2)

Distribute:

= 2x+ (−3)(2x) + (−3)(−2)

= 2x+ −6x + 6

Combine Like Terms:

= 2x + −6x + 6

= (2x + −6x) + (6)

= -4x + 6

Simultaneous Equation <br><br> (x+5)(x+2)=65 , xy=24<br><br> Plssss help me ✌
Ne4ueva [31]

Answer:

  • (-11.70, -2.05), (4.70, 5.10)

Step-by-step explanation:

<u>Given equations</u>

  • (x+5)(x+2)=65
  • xy=24

<u>Solving the first equation for x:</u>

  • (x+5)(x+2)=65
  • x^2 + 7x + 10 = 65
  • x^2 + 7x - 55 = 0
  • x = (-7 ± √(49+4*55))/2
  • x = -11.70, x = 4.70

<u>Then solving for y:</u>

  • y= 24/(-11.7) = -2.05
  • y = 24/4.7 = 5.10

<u>Solution set: </u>

  • (-11.70, -2.05), (4.70, 5.10)
