Answer:

Factoring

Step-by-step explanation:

(x+4)² = 15

x² + 8x + 16 = 15

x² + 8x + 1 = 0

x =  \frac{ - 8 +  \sqrt{64 - 4} }{2}  =  - 4 +  \sqrt{15}  \\  \\ x =  \frac{ - 8 -  \sqrt{64 - 4} }{2}  =  - 4 -  \sqrt{15}

I hope this helps you :)

What’s the distance between (3,4) , (7,2)
Reptile [31]

Answer:

D= 4.47

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

 

Where

(x_1,y_1) = (3,4)

(x_2,y_2) = (7,2)

 

Replacing these values in the distance formula

D =\sqrt{(7-3))^2+(2-4)^2}

D =\sqrt{(4)^2+(-2)^2}

D =\sqrt{16+4}

D =\sqrt{20}

D= 4.47

Help asap
mylen [45]

Answer:

B.2 1/41

Step-by-step explanation:

In a perfect square trinomial of the form ax+bx+c where a, b and c are constants, the value of (b/2)²=ac

In the provided equation the value of a=1, b=-3 c=?

Therefore, (-3/2)²=c since a-the coefficient of x²=1 and 1×c=c

c=2.25= 2 1/4

Thus the trinomial x² - 3x + 2 1/4 is a perfect square.
