Is that a minus sign in between the x) and x=8?
the last step is wrong because we multiply the powers in this case we do not subtract them.
we use power subtract in division.
we use power multiplication when we raise to power and the root is power like square root of x
so
![\sqrt[3]{x} = {x}^{ \frac{1}{3} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bx%7D%20%20%3D%20%20%7Bx%7D%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20)
in our case
this step is wrong
![2x \times \sqrt[3]{ \frac{2}{y} \times \frac{y}{y} }](https://tex.z-dn.net/?f=2x%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B2%7D%7By%7D%20%20%5Ctimes%20%20%5Cfrac%7By%7D%7By%7D%20%7D%20%20)
it should be
![2 x \times \sqrt[3]{ \frac{2}{y} \times \frac{ {y}^{2} }{ {y}^{2} } }](https://tex.z-dn.net/?f=2%20x%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B2%7D%7By%7D%20%20%5Ctimes%20%20%5Cfrac%7B%20%7By%7D%5E%7B2%7D%20%7D%7B%20%7By%7D%5E%7B2%7D%20%7D%20%7D%20)
so we get
![2x \times \sqrt[3]{2 {y}^{2} \times \frac{1}{ {y}^{3} } }](https://tex.z-dn.net/?f=2x%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B2%20%7By%7D%5E%7B2%7D%20%5Ctimes%20%20%5Cfrac%7B1%7D%7B%20%7By%7D%5E%7B3%7D%20%7D%20%20%7D%20)
![= \frac{2x}{y} \times \sqrt[3]{2 {y}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B2x%7D%7By%7D%20%20%5Ctimes%20%20%5Csqrt%5B3%5D%7B2%20%7By%7D%5E%7B2%7D%20%7D%20)
Answer:
Just list all the coefficients.
Step-by-step explanation:
one thing to know
If a variable is just there, like x, it's coefficient is always a one

Answer: 95°
Step-by-step explanation: We are given information for Angles 1 and 4, which happen to be vertical angles, meaning they are congruent. Because of this, we can say 3x+10=4x-15, therefore x=25. Angles 1,2,3 and 4 must add up to 360°, and since we know angles 1 and 4 are 85° (3*25 + 10 = 85), we can find angles 2 and 3. 360° - 85° - 85° = Angle 2 + Angle 3. Angle 2 + Angle 3 = 190, and because Angles 2 and 3 are vertical angles and therefore congruent, we can divide 190 by 2 and get that Angles 2 and 3 equal 95°. Because lines b and c are parallel, any corresponding angles created by a transversal are congruent. This basically means Angles 3 and 7 must be congruent, therefore Angle 7 = 95°
Congruent - same meaning as equal
Vertical Angles - each of the pairs of opposite angles made by two intersecting lines.
