Solve this equation. <br> Leave the answer as an improper fraction. <br> 3x^2 + 2 = 11 - x^2

Nikolay [14]

Answer:

$x = \frac{3}{2}orx=-\frac{3}{2}$

Step-by-step explanation:

The given Equation is

$3x^{2} + 2 = 11-x^{2}$ .................(i)

Adding ( $x^{2} -11$ ) on both sides of (i)

$3x^{2}+2+x^{2}-11 = 11-x^{2}+x^{2}-11$

solving and cancelling out the terms will give

⇒ $4x^{2} -9=0$

⇒ $(2x)^{2} -(3)^{2} = 0$ ...................(ii)

Now we Know that

$(a)^{2} -(b)^{2} = (a-b)(a+b)$

Applying this on equation (ii)

$(2x-3)(2x+3)=0$

This will lead us to

Either 2x-3 =0 .......(iii) or 2x+3=0 ..........(iv)

Solving equation (iii) for value of x

2x - 3 =0

adding 3 on both sides

2x -3 +3 = 0+ 3

2x = 3

Cross multiplying gives

$x=\frac{3}{2}$

Solving equation (iv) for value of x

2x + 3 =0

adding -3 on both sides

2x -3 +3 = 0- 3

2x = -3

Cross multiplying gives

$x=\frac{-3}{2}$

so $x=\frac{3}{2}$ and $x=\frac{-3}{2}$

The figure is a parallelogram.<br> Solve for x.

lions [1.4K]

Answer:

x = 7

Step-by-step explanation:

Adjacent angles of a parallelogram are supplementary.

$\therefore \: (14x + 2) \degree + 80 \degree = 180 \degree \\ \\ \therefore \: (14x + 2) \degree = 180 \degree - 80 \degree \\ \\ \therefore \: (14x + 2) \degree = 100 \degree \\ \\ 14x + 2 = 100 \\ 14x = 100 - 2 \\ \\ 14x = 98 \\ \\ x = \frac{98}{14} \\ \\ x = 7$
