Answer:
<em> (1). x = 14 ; (2). 70°</em>
Step-by-step explanation:
<em>(1).</em> m∠ACD = m∠A + m∠B
6x + 2 = (2x + 1) + (3x + 15)
6x - 5x = 14
<em>x = 14</em>
<em>(2).</em> m∠ABC = 180° - m∠CBD = 140°
<em>m∠A</em> = m∠C = 140° ÷ 2 = <em>70°</em>
Answer:
![24\sqrt[3]{x^{7}}](https://tex.z-dn.net/?f=24%5Csqrt%5B3%5D%7Bx%5E%7B7%7D%7D)
Step-by-step explanation:
The exponent rule that applies to products like this is ...
... (a^b)(a^c) = a^(b+c)
In your problem, this is
... x^(1/3)·x^2 = x^(1/3 +2) = x^(1/3 +6/3) = x^(7/3)
This fractional exponent translates to the root of a power:
... = (x^7)^(1/3)
In typeset form, it is ...
![\sqrt[3]{x^{7}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B7%7D%7D)
You have already figured correctly that the coefficient is 3·8 = 24.
The answer is 19.125 or you can round it to 19.13
Answer:
Step-by-step explanation:
The third digit can be 8 6 4 2 or 0
The last digit can be 4 3 2 1 or 0
The second digit 8 4 0 which makes the last digit 2 1 0
The first digit is 3
The choices are
The first digit is 3. That's all you can be sure of. Lets assume zero is not a choice.
3 8 4 2
3 4 2 1
