Answer:

<em>=10x^2+8x+3</em>

Step-by-step explanation:

Lets simplify step by step.

=5x^2+3x+4+5x^2+5x+-1

Combine like Terms.

=5x^2+3x+4=5x^2+5x=-1

=(5x^2+5x^2)+(3x+5x)+(4+-1)

=10x^2+8x+3

<u><em>=10x^2+8x=3</em></u>

Determine if the triangles, CEG and DEF ,are similar. If so, identify the similarity
Harlamova29_29 [7]

Answer:

A

Step-by-step explanation:

AA similarity means 2 angles must be similar.

Angle 1: Angle E is the same for both triangles

Angle 2: Angle F and angle G are congruent because they both have right angle markings so they are both 90 degrees.

The floor of a room is being covered with tile. An area one half
tangare [24]

Answer:

Only the floor area \frac{3}{8} has been covered

Step-by-step explanation:

Assuming that the floor of the room is rectangular, then its area is equal to the product of its length times its width.

A = lw

Let's now call A 'the area that was covered with tiles.

We know that half the length was covered, then:

l' = \frac{1}{2}l

w' = \frac{3}{4}w

So:

A' = \frac{1}{2}l(\frac{3}{4}w)

A' = \frac{3}{8}lw

Finally:

A' = \frac{3}{8}A

Select the vertical asymptote(s) of the function <img src="https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B%28x%2B6%29%28x-1%29%7D%
Bess [88]

Answer:

As the described function, we want to find vertical asymtotes, we find the value of x so that the denominator is equal to 0.

Here, (x - 2)(x + 6) = 0

=> x = 2, x =-6

=> Option C is correct.

Hope this helps!
