answer:

there is a pattern with the ratios of corresponding sides. you can see that the measurement of each side of the first triangle divided by two is the measure of the corresponding side of the second triangle. use patterns like this to problem solve the length of missing sides of similar triangles.

good luck :-)

hopefully, this helps

have a great day !!

Solving quadratic equation using the completing method.<br>(a).x^2+6x+1=0

irina1246 [14]

Answer:

$x = -3 + 2\sqrt2 \ , \ x = -3 - 2\sqrt2$

Step-by-step explanation:

x² + 6x + 1 = 0

a = 1 , b = 6 , c = 1

$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\x = \frac{-6 \pm \sqrt{36-4}}{2}\\\\x=\frac{-6 \pm \sqrt{32}}{2}\\\\x= \frac{-6 \pm \sqrt{16 \times 2}}{2}\\\\x = \frac{-6 +4\sqrt2 }{2}\\\\x = -3 + 2\sqrt2 \ , \ x = -3 - 2\sqrt2$

What is the end behavior of the graph?

hichkok12 [17]

Imagine that this curve is a roller coaster. A dot on the roller coaster would be a car for a person to sit in, so to speak. As this car moves to the right, the car ultimately moves downward. So this means that as x gets larger, y gets smaller. Put another way: as x approaches infinity, f(x) approaches negative infinity.

Similarly, we can move the other way to work our way to the left. Moving to the left has us go up this time. As x approaches negative infinity, f(x) approaches positive infinity

These two facts point to choice B as the final answer

PLEASE HELP ILL GIVE BRAINLIEST

Alexxx [7]

Answer:

Answer is 25ft.

Step-by-step explanation:

l=20ft.

h=16ft.

let 'w' be x.

then

l=√w2+h2

or l=√x2+(16)2

squareing on both side.

or (20)2=√(x+16)2

or 400=x+16

or x=400/16

or x=25.

so that the value of W is 25ft.
