What is the set of all solutions to the equation \sqrt{x + 2}= {-x} x+2 =−xsquare root of, x, plus, 2, end square root, equals

NARA [144]

Answer:

$x = 2$ or $x = -1$

Step-by-step explanation:

Given

$\sqrt{x + 2}= {-x}$

Required

Find the possible values fo x

$\sqrt{x + 2}= {-x}$

Square both sides

$( \sqrt{x + 2})^2= ({-x})^2$

$x + 2 = x^2$

Equate to 0

$x^2 - x - 2 = 0$

Expand

$x^2 + x -2x - 2 = 0$

Factorize:

$x(x + 1) - 2(x + 1) = 0$

$(x -2)(x +1) = 0$

Split:

$x - 2 = 0$ or $x + 1 = 0$

$x = 2 + 0$ or $x = 0-1$

$x = 2$ or $x = -1$

Monica has a 24

melamori03 [73]

Answer:

The fraction of frame did Monica paint blue is $\frac{3\sqrt{6}}{2}$

Step-by-step explanation:

Given as :

The area of square frame = A = 24 square inches

Monica paint $\frac{3}{4}$ of one side of the frame blue

Let the measure of one side of frame = x

So, From Area of square

Area = side × side

Or, A = x × x

Or, x ² = 24

∴ x = $\sqrt{24}$ = 2 $\sqrt{6}$

So, Measure of each side = x = 2 $\sqrt{6}$

Now, As Monica paint $\frac{3}{4}$ of one side of the frame blue

So, The painted part = $\frac{3}{4}$ × 2 $\sqrt{6}$

∴ The painted part = $\frac{3}{2}$ × $\sqrt{6}$

I,e The fraction of painted blue = $\frac{3\sqrt{6}}{2}$

Hence, The fraction of frame did Monica paint blue is $\frac{3\sqrt{6}}{2}$ Answer

Solve the triangle. A = 46° a = 33 b = 26

frozen [14]

Using sin rule:
a/sin A =b/sin B=c/sin c
SIN A=sin 46=0.72
THEN:sin B =(0.72*26)/33=0.57
then B= 34°
AS the sum of triangle angles=180
then C=180-(46+34)=100°
then c =(a*sin C)/sin A
sin C=sin 100=0.98
=(33*0.98)*0.72=45
