Answer:
x = 20
Step-by-step explanation:
Intersecting Chords Theorem: ab = cd
Step 1: Label our variables
<em>a</em> = x
<em>b</em> = x - 11
<em>c</em> = x - 8
<em>d</em> = x - 5
Step 2: Plug into theorem
x(x - 11) = (x - 5)(x - 8)
Step 3: Solve for <em>x</em>
x² - 11x = x² - 8x - 5x + 40
x² - 11x = x² - 13x + 40
-11x = -13x + 40
2x = 40
x = 20
Answer:
v = -16
Step-by-step explanation:
<u>→Distribute the 5 to (-7v - 11):</u>
14 - 10v + 11 = 20v - 35v - 55
<u>→Add like terms:</u>
25 - 10v = -15v - 55
<u>→Add 15v to both sides:</u>
25 + 5v = -55
<u>→Subtract 25 from both sides:</u>
5v = -80
<u>→Divide both sides by 5:</u>
v = -16
Answer:
A
Step-by-step explanation:
Hi!
An exponent is the same thing as just multiplying the expression by itself the number of times the exponent says. So we need to multiply 1/3 by itself three times.
1/3 * 1/3 * 1/3 = 1/27
