Answer:

Option A true is the answer.

Step-by-step explanation:

The given circle there are two arcs AB and CD.

Angles formed by these arcs at the center arc 30°

Formula of length of arc = r × θ

where r = radius of the circle

and θ = angle formed by arc at the center.

mAB = OA × (30°) [ By formula ]

similarly mCD = DC × (30°)

Since OA = OC = r (radii of the circle )

So mAB = mCD

Therefore, statement is true.

Option A true is the answer.

How do you solve 4s+5=19

kolbaska11 [484]

4s + 5 = 19

First, subtract 5 from both sides. / Your problem should look like: 4s = 19 - 5.
Second, simplify 19 - 5 to 14. / Your problem should look like: 4s = 14.
Third, divide both sides by 4. / Your problem should look like: s = $\frac{14}{4}$ .
Fourth, simplify $\frac{14}{4}$ to $\frac{7}{2}$ . / Your problem should look like: s = $\frac{7}{2}$ which is the answer.

Simplify the following rational expression.

Answer:

(x-8)/(4x-4) x ≠ 1 or 8

Step-by-step explanation:

Common factors can be cancelled, but cannot be ignored when it comes to determining where the function is undefined.

$\dfrac{x^2-16x+64}{4x^2-36x+32}=\dfrac{(x-8)^2}{4(x-8)(x-1)}=\boxed{\dfrac{x-8}{4x-4}}$

The function is undefined for x=1 and x=8, the values of x that make the original denominator zero.
