Answer:

Step-by-step explanation:

$\frac{\sqrt{x}+1 }{x-\sqrt{x}+1 }=\frac{\sqrt{x}+1}{(x+1)-\sqrt{x}}\\\\=\frac{(\sqrt{x}+1)([x+1]+\sqrt{x})}{([x+1]-\sqrt{x})+([x+1)+\sqrt{x}])}\\\\=\frac{\sqrt{x}*x+\sqrt{x}*1+\sqrt{x}*\sqrt{x}+1*x+1*1+1*\sqrt{x}}{(x+1)^{2}-(\sqrt{x})^{2}}\\\\\\=\frac{x\sqrt{x}+\sqrt{x}+x+1+x+\sqrt{x}}{x^{2}+2x+1-x}\\\\=\frac{x\sqrt{x}+2\sqrt{x}+2x+1}{x^{2}+x+1}\\\\$

Answer:

First Question:

0042=4210000=42104=42⋅1104.

HELP ME PLEASE! I WILL GIVE BRAINLIEST LOTS OF POINTS

Number the tables as follows:

1 2
3 4

Eliminate 3 and 4 immediately, because for x = 2 the y values are wrong (3 and 1).

In tables 1 and 2, the input (1) produces the correct output (-1).

So we have to determine which table agrees 100% with the system of equations given.

Comparing tables 1 and 2, row by row, we see that their contents are the same EXCEPT for the first rows. So focus on determing which of those 2 rows displays values that satisfy both given equations.

First I looked at y=2x-5, and subst. -1 for x. I got -7, which is correct in table 1 but not in table 2 (where the value would be -13).

Thus, table 1 correct represents the solution of the system of equations.

Q # 17. please help me with this

vredina [299]

Hi there!

Dimensions of rectangular room :-

• Length = 109 inches
• Breadth = 103 inches

Dimensions of square tiles :-

• Each side = 3 inches

It's known :-

No. of tiles = Area of rectangular room / Area of tile

No. of tiles = $\dfrac {109 × 103}{3}$

No. of tiles = $\dfrac {11227}{9}$

No. of tiles = 1,247

Hence,
Th' number of tiles required for the job is 1,247

~ Hope it helps!
