Find the value of x in the circle below. Assume that lines that appear to be tangent are tangent.8O2O48OO12

Mathematics

If one of the lines is tangent (the one whose length equals 8) and the other line is secant (the one that goes from the that intersects the circle), then the square of the length of the tangent is equal to the product of the external secant segment and the total length of the secant, like this:

8²=4×(4+x)

From this equation we can solve for x like this:

64 = 4×4 + 4x

64 = 16 + 4x

64 - 16 = 4x

48 = 4x

12 = x

x = 12

Then, x equals 12

The number sentence 4x6=6x4 is an example of the what property
monitta

Answer:

commutative property of multiplication

Step-by-step explanation:

The value of the product of the given equation remain the same while the order is reversed

The number sequence 4 × 6 = 6 × 4 is an example of the commutative property of multiplication

Reason:

The given number sentence is 4 × 6 = 6 × 4

Required: The property the number sentence is an example of (represent)

Solution:

The difference between the left and right expression is that the order of the

values being multiplied is changed or reversed (commute)

Therefore, the number sentence states that the value of the multiplication

of two variables remain equal when the places of variables are

interchanged as follows; a × b = b × a

a × b = b × a is an example of commutative property of multiplication

Therefore;

4 × 6 = 6 × 4 is an example of the commutative property of multiplication
