Answer:

Length of Arc = 4

Step-by-step explanation:

Circumference is the whole circle's perimeter.

Arc length is a "part" of the circumference.

Whole circle is 360 degrees, so the arc length with a central angle of 72 degrees will be:

72/360 = 1/5th of the whole circle

The whole circle has circumference of "20", so 1/5 th of that would be:

(1/5) * 20 = 4

Length of Arc = 4

Leftover Expression
Mumz [18]

The second leftover expression is not o(a+b). It is 6(a + b). I have attached the correct question to depict that.

Answer:

The equivalent expressions are;

8a + 2 and 6a + 6b

Step-by-step explanation:

The two leftover expressions are given as;

2(4x + 1) and 6(a + b)

In algebra, equivalent expressions are simply those expressions which when simplified, give the same resulting expression as the initial one.

Thus simply means expanding or collecting like times to make it clearer.

Now, in our question, like terms have already been collected. This means that to find an equivalent expression, we will just expand the bracket.

Thus;

2(4x + 1) will be expanded by using the 2 outside the bracket to multiply the terms inside the bracket. This gives;

8x + 2

Similarly,

6(a + b) will be expanded by using the 2 outside the bracket to multiply the terms inside the bracket. This gives;

6a + 6b

Thus;

The equivalent expressions are;

8a + 2 and 6a + 6b

Bas_tet [7]

Step-by-step explanation:

use Pythagoras theorem,

{a}^{2}  +  {b}^{2}  =  {c}^{2}

{6}^{2}  +  {8}^{2}  =  {c}^{2} \\ 36 + 64 =  {c}^{2}  \\ c = \sqrt{100 }   \\ c = 10
