= 2(2x + 5)

Step-by-step explanation:

Given that:

= (7x + 5) - (3x - 5)

By simplifying

"-" sign before bracket will alter the inner signs

= 7x + 5 - 3x + 5

Adding like terms

Answer:

Step-by-step explanation:

<h3>7) The lengths of the tangent from an external point to a circle are equal.</h3>

2x - 1 = x + 10

2x = x + 10 + 1

2x = x + 11

2x -x = 11

$\sf \boxed{\bf x = 11}$

8) Radius : XC

Chord: CB

Diameter : AB

Compute 1 + 2 + 3 +....+ 1,997 + 1,998 + 1,999

sp2606 [1]

Answer:

1 999 000

Step-by-step explanation:

Formula:

$1+2+3+.\ .\ .+n=\frac{n\times \left( n+1\right) }{2}$

………………………………………

Then

$1+2+3+....+1997+1998+1999=\frac{1999\times \left( 1999+1\right) }{2}$

$1+2+3+....+1997+1998+1999=\frac{1999\times \left( 2000\right) }{2}$

$1+2+3+....+1997+1998+1999=\frac{3998000 }{2}$

$1+2+3+....+1997+1998+1999=1999000$
