Find the solutions to the equation below.

taurus [48]

2x²+7x+3=0

2x²+(1+6)x+3=0

2x²+1x+6x+3=0

x(2x+1)+3(2x+1)=0

(2x+1)(x+3)=0

2x+1=0. x+3=0

2x=-1. x=-3

x=-1/2

What is midpoint of A(2, 3) and B(-2, 5)?

Elis [28]

Answer:

The midpoint of A and B is (0, 4).

Step-by-step explanation:

Use the midpoint formula, ((x₁ + x₂)/2 , (y₁ + y₂)/2)

First, solve for the x part.

(2 + (-2))/2

0/2

0

So the x-coordinate of the midpoint is 0.

Then, solve for the y part.

(3 + 5)/2

8/2

4

So the y-coordinate of the midpoint is 4.

The product of a binomial and a trinomial is x3+3x2-x+2x2+6x-2 Which expression is equivalent to this

solong [7]

The answer is the first one.
Explanation:
X^3 stays the same because there are no other cubed numbers in the problem
Next you combine the x^2s
The x^2s are +3x^2 and +2x^2
Since they are both positive, you add them: 3x^2 + 2x^2 = 5x^2
Next you do the x values
-x and +6x, also known as 6x - x = 5x
Lastly, you just add in the -2 and get:
X^3 + 5x^2 + 5x - 2

In the diagram the length of segment TR can be represented by 5x-4.

masya89 [10]

Answer: The correct option is D, i.e., 15 units.

Explanation:

It is given that the length of segment TR can be represented by 5x-4.

From figure it is noticed that the side TR and RV is equal and the length of segment RV is 2x+5. So,

$5x-4=2x+5$

$3x=9$

$x=3$

The value of x is 3, so the length of side RV is,

$2x+5=2(3)+5=11$

In triangle TRS and angle VRS,

TR=VR

$\angle TRS=\angle VRS=90^{\circ}$

RS=RS (common side)

By SAS rule of congruence triangle,

$\triangle TRS\cong\triangle VRS$

Therefore the side TS and VS are congruent sides.

From figure it is noticed that the length of side TS is 6x-3, therefore the length of side VS is also 6x-3.

$VS=6x-3=6(3)-3=15$

Hence, the length of side VS is 15 units and option D is correct.
