5x - (2x - 1) = 2

Distribute the - sign.

5x - 2x + 1 = 2

Combine like terms.

3x + 1 = 2

Subtract 1 from both sides.

3x = 1

Divide both sides by 3

x = 1/3 or 0.33

Anybody can help?????

The formula of an area of a circle:

A=\pi r^2

r - a radius

We have r = 14m. Substitute:

A=\pi\cdot14^2=196\pi\ m^2

If you want an approximate area, you can accept \pi\approx3.14

Then:

A\approx196\cdot3.14=615.44\ m^2

So the perimeter would be about 46. But 46.48 exactly.

For what value of x is PQ || BC?<br> A 5<br> B. 6<br> C. 7<br> D. 8
Dahasolnce [82]

Answer:

C. 7

Step-by-step explanation:

In\: \triangle ABC\\\overline{PQ} \parallel \overline {BC}.. (given) \\

Therefore, by Basic Proportionality theorem:

\frac{AP}{PB} = \frac{AQ}{QC} \\\\\therefore \frac{x}{x+7} = \frac{x-3}{x+1} \\\\ \therefore \:  \frac{x - x - 7}{x + 7}  =  \frac{x - 3 - x - 1}{x + 1}  \\ (by \: dividendo) \\  \\  \frac{ - 7}{x + 7}  =  \frac{ - 4}{x + 1}  \\  \\  \frac{7}{x + 7}  =  \frac{4}{x + 1}  \\  \\ 7x + 7 = 4x + 28 \\  \\ 7x - 4x = 28 - 7 \\  \\ 3x = 21 \\  \\ x =  \frac{21}{3}  \\  \\ \huge \red{ \boxed{ x = 7}}
