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

3c-d=T<br> Could you<br> solve for c
RSB [31]
- - Let's solve for C.

Starting off with our equation:
3c+d=T

Transform:
3c=T+D

Solve for that:
\frac{3c}{3} = \frac{T+D}{3}


Solve for that for the last time and your answer is \frac{T+D}{3} =C

What are the roots of the quadratic equation 2x2+7x+4=0? Select all that apply.
skad [1K]

Answer:

option A and B

x=\frac{-7+\sqrt{17}} {4}

and

x=\frac{-7-\sqrt{17}} {4}

Step-by-step explanation:

we have

2x^2+7x+4=0

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}

in this problem we have

2x^2+7x+4=0

so

a=2\\b=7\\c=4

substitute in the formula

x=\frac{-7\pm\sqrt{7^{2}-4(2)(4)}} {2(2)}

x=\frac{-7\pm\sqrt{17}} {4}

so

x=\frac{-7+\sqrt{17}} {4}

and

x=\frac{-7-\sqrt{17}} {4}
