What is (x+5)+2x^2=2x+1
andrew-mc [135]

Answer:

Step-by-step explanation:

Area of Square = (x+5)²= x² + 10x + 25

Area of rectangle = 2x  * x  = 2x²

area of rectangle + 1 = Area of square

 2x² + 1 = x² + 10x +25

2x² + 1 - x² - 10x - 25 = 0

x²  - 10x - 24 = 0

(x - 12) (x + 2) = 0

x - 12 = 0   ;   Ignore x + 2  because length wont come in negative

x = 12

Melinda takes out a loan to purchase a car. The balance on her loan after x months is represented by the equation y = 10,000 – 2
Arlecino [84]

Answer:

Melinda's loan will be equal to the value of the car after 10 months.

Step-by-step explanation:

We are given,

Balance on the loan is given by, y = 10,000 - 250x.

Also, Value of the car is given by, y = 8,000 - 50x.

Since, it is required to make Melinda's loan equal to the value of the car.

We have,

10,000 - 250x = 8,000 - 50x.

i.e. 250x - 50x = 10,000 - 8,000

i.e. 200x = 2,000

i.e. x = 10.

Thus, Melinda's loan will be equal to the value of the car after 10 months.

Addition (must show work) can someone solve 1. m + 13 =29 2. z + x =34 <br><br> 3. 87 + p = 136
azamat

Greetings ! Your Answer Is Below.

Answer;

1. m = 16

2. x = -z + 34 or z = -x + 34

3. p = 49

Step-by-step explanation;

1. m + 13 - 13 = 29 - 13       | Subtract 13 from both sides ( m = 16 )

2. - z + 34                          | Add -z to both of the sides ( x = - z + 34 )

Or - x + 34                         | Add -x to both of the sides ( z = - x + 34 )

3. 136 - 87 = 49                 | Subtract 87 from both sides ( p = 49 )
