Two.

Square root of 2 = 1.414213562... Square root of 7 = 2.645751311... The sum is 4.059964873...

7+10+(-6x)=17-6x

10 square root of 3.

-6x^2 - 78x - 252 Improved answer: -6x+6x+7 When simplified = 7

The square root of 9 is 3, therefore 3 + 7 = 10

It is: 4+7 = 11

if x^2 = 49, then the square root property says you can take the square root of both sides as long as you make one a plus-minus. x^2 = 49, which means square root of x^2 = plus minus the square root of 49 the square root of 49 is 7, so +- 7. We get: x = plus/minus 7 (this means either positive 7 or negative 7)

x^2 - 6x + 5x + 7 = 0 => x^2 - x + 7 = 0The roots of this equation are0.5 - 2.5981*i and 0.5 + 2.5981*i where iis the imaginary square root of -1.

4x + 7 = 6x -7 14=2x so x = 7 (plus a negative # is simply - that number)

No, it is not.

f(x)=6x2+7x+2 f(x)=(6x+1)(x+2) x= -1/6 and x= -2 The above answer is not correct. (6x+1)(x+2) yields 6x2+13x+2, not the original equation. The answer can be arrived at using the quadratic equation, where ax2+bx+c=0 and x=[-b (+-) square root(b2-4ac)] / 2a x=[-7(+-) square root (72-4(6)(2))] / 2(6) x=[-7(+-)square root(49-48)]/12 x=[-7(+-)1]/12 x=-1/2 and -2/3

Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)

y = x2 - 6x + 2 y = x2 - 6x + 9 - 7 y = (x - 3)2 - 7

It already is in the form a+ib. a = root 7, the b=1 (i.e 1 x i ).

x2 + 6x = 7 ⇒ x2 + 6x + 9 = 7 + 9 ⇒ (x + 3)2 = 16 ⇒ x + 3 = ±4 ⇒ x = -7 or 1

I believe the answer to that is 11.000128147136572

Plus or minus 7.

Thanks to limitations of the browser used for posting questions, it is not possible to tell whether the sides are 6x - 7 units or 6x + 7 units. For 6x - 7 units, area = 36x2 - 84x + 49 square units. For 6x + 7 units, area = 36x2 + 84x + 49 square units.

7 plus the square root of 5 is an irrational number because the square root of 5 is a never ending decimal number that can't be expressed as a fraction.

The square root of 49 is +7 OR -7 So the answers are -65/6 and 71/6 or -6.8333... and 7.1666...

That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (3 plus or minus the square root of 2) divided by 7. x = 0.6306019374818707 x = 0.2265409196609864
