Not sure if this is right but I would just expand it out again to get 8x-20. ?

Using the distributive property, we can go 4(2x) - 4(5) which would equal 8x-20.
Hope this helps and please give brainliest!

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

Name of the circle: X {a circle is named by its center}

Answer:

$\sf 500,000,000,000=5 \times 10^{11}$

$\sf 0.00000000005=5 \times 10^{-11}$

Step-by-step explanation:

Scientific notation

$\large\boxed{a \times 10^n}$

where:

$1\leq a < 10$

$n$ is any positive or negative whole number.

To convert a number into scientific notation, move the decimal point to the left or right until there is one digit to the left of the decimal point.

The number of times you have moved the decimal point is $n$ .

If the decimal point has moved to the left, $n$ is positive.
If the decimal point has moved to the right, $n$ is negative.

To convert 500,000,000,000 into scientific notation, move the decimal point 11 places to left, so a = 5. As we have moved the decimal point 11 places to the left, the exponent "n" is 11 and is positive.

$\implies \sf 500,000,000,000=5 \times 10^{11}$

To convert 0.00000000005 into scientific notation, move the decimal point 11 places to the right, so a = 5. As we have moved the decimal point 11 places to the right , the exponent "n" is 11 and is negative.

$\implies \sf 0.00000000005=5 \times 10^{-11}$
