What is the power of x? <br> A) 2 <br> B) 3 <br> C) 6 <br> D) 7
Thepotemich [5.8K]

Answer:

A

Step-by-step explanation:

They are basically wanting the value of x.

These are 2 secant lines drawn. Secant Line is a line that intersects the circle at 2 points.

To solve this, we have to use secant-secant theorem.

Secant-Secant Power Theorem tells us that if 2 secant lines are drawn from external point (here, E) to a circle, then, product of measure of one secant's external part and total secant is equal to other secants external part and whole secant.

In algebra, that is:

(x+1)(x+1+11)=(x+4)(x+4+1)

Let's multiply and find the value of x:

(x+1)(x+1+11)=(x+4)(x+4+1)\\(x+1)(x+12)=(x+4)(x+5)\\x^2 + 13x + 12=x^2+9x+20\\13x+12=9x+20\\13x - 9x = 20 - 12\\4x = 8\\x = 2

Hence, the correct answer choice is A

Will 1/4 x 7/8 be larger or smaller than 1/4? Explain your answer.
sweet-ann [11.9K]
It will be smaller than 1/4.

The reason being that 7/8 is a fraction which is less than 1, and that it can only be greater than 1/4 when the multiplying number, is a number which is greater than 1.

Note: When  a positive number is multiplied by a number which is less than 1, it makes the positive number to be smaller and

When a positive number is multiplied by a number which is greater than 1, it makes the positive number to be bigger.

Multiply 5.5395 by factors of 10, 100, and 1000.
qwelly [4]

Answer:

I) 55.395

ii) 553.95

iii) 5539.5

Step-by-step explanation:

If we multiply 5.5395 by 10, the decimal point moves forward once

5.5395 \times 10 = 5.5395 \times  {10}^{1}  = 55.395

If we multiply by 100, the decimal point moves forward 2 times.

5.5395 \times 100 = 5.5395 \times {10}^{2}  = 553.95

If we multiply 5.5395 by 1000, the decimal point moves forward three times.

5.5395 \times 1000 = 5.5395 \times {10}^{3}  = 5539.5

How can I solve for x?
anygoal [31]

Answer:

37 degrees

Step-by-step explanation:

The angles within a triangle always add up to 180 degrees. Right angles are always 90 degrees. 53 + 90 = 143 degrees. 180 - 143 = 37 degrees
