Solve using Quadratic Formula <br>x^2 + 3x - 3 = 0

katrin [286]

Answer:

a= 1 , b= 3 , c= –3

$x = \frac{ - b \frac{ + }{} \sqrt{ {b}^{2} - 4ac} }{2a} \\ x = \frac{ - 3 \frac{ + }{} {} \sqrt{ {3}^{2} - 4(1)( - 3)} }{2(1)} \\ = \frac{ - 3 \frac{ + }{} \sqrt{9 + 12} }{2} = \frac{ - 3 \frac{ + }{} \sqrt{21} }{2} \\ \\ x = \frac{ - 3 \frac{ + }{} \sqrt{21} }{2} \\ \\ x = 0.79 \\ x = - 3.79$

Could someone help me please?

Answer:

a. 7.2

b. 6

Step-by-step explanation:

Since the side lengths of similar polygons are proportional to each other, therefore:

$\frac{b}{10} = \frac{9}{15} = \frac{a}{12}$

Thus, let's find b using:

$\frac{b}{10} = \frac{9}{15}$

Cross multiply

$b*15 = 10*9$

$15b = 90$

Divide both sides by 15

b = 6

Let's find a using:

$\frac{9}{15} = \frac{a}{12}$

Cross multiply

9*12 = 15*a

108 = 15a

Divide both sides by 15

a = 7.2

Selection D) is appropriate.

The triangles are congruent by SSA, given the angle is a right angle, not ASA or AA. YX is not congruent to UW, so C) is incorrect.

If K is the midpoint of HJ, HK equals x+6, and HJ equals 5x-6, then KJ equals?

Natasha2012 [34]

X + 6 = 5x - 6
12 = 4x
x = 3
KJ = 2 ( x+ 6 ) = 2 * 9 = 18
