Answer:

x = - 3 ± \sqrt{2}

Step-by-step explanation:

x² + 6x + 7 = 0 ( subtract 7 from both sides )

x² + 6x = - 7

using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = - 7 + 9

(x + 3)² = 2 ( take square root of both sides )

x + 3 = ± \sqrt{2} ( subtract 3 from both sides )

x = - 3 ± \sqrt{2}

Which expression is equivalent to the following complex fraction?
tatyana61 [14]
\dfrac{\frac{x}{x-3}}{\frac{x^2}{x^2-9}}=\dfrac{x(x^2-9)}{(x-3)x^2}=\dfrac{x(x+3)(x-3)}{(x-3)x\cdot x}=\dfrac{x+3}{x}

Answer C.

What is the radius pf a circle whose equation is (x+5)^2+(y-3)^2=4^2
Lerok [7]

Answer:

we know that

the equation of the circle is of the form

(x-h)^2+(y-k)^2=r^2

where

(h,k) is the center of the circle

r is the radius of the circle

in this problem we have

(x+5)^2+(y-k)^2=r^2

so

the center is the point (-5,3)

the radius is 4 units

therefore

the answer is

The radius of the circle is equal to 4 units

The ratio of red cars to blue cars in a parking lot was 5:3 . If there was 40 red cars , how many blue cars were there ?
Bas_tet [7]
The answer is x equals 24
you set up a proportion new over old
so for red cars 40 over 5
since we don’t know the new for blue cars we’ll use x
so x over 3
we then make them equal to each other
40 x
—- = —-
5 3
cross multiply, then we get
120=5x
isolate the x by dividing 5 from both sides to get 24
