Hi there!  

»»————- ★ ————-««

I believe your answer is:  

170

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

\text{The phrase can be rewritten as:}\\\\10 * (8-(-9))\\---------------\\\rightarrow 8-(-9) = 8 + 9 = 17\\\\\rightarrow 10 * 17\\\\\rightarrow \boxed{170}

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

How many solutions does the equation have? 6-a = 1/3(9a-18)
Alex777 [14]
6 - a = \frac{1}{3} (9a - 18)

First, simplify \frac{1}{3} (9a - 18) to \frac{9a-18}{3} / Your problem should look like: 6 - a =  \frac{9a - 18}{3}
Second, multiply both sides by 3. / Your problem should look like: 18 - 3a = 9(a - 2)
Third, expand. / Your problem should look like: 18 - 3a = 9a - 18
Fourth, add 3a to both sides. / Your problem should look like: 18 = 9a - 18 + 3a
Fifth, simplify 9a - 18 + 3a to 12a - 18. / Your problem should look like: 18 = 12a - 18
Sixth, add 18 to both sides. / Your problem should look like: 18 + 18 = 12a
Seventh, add 18 + 18 to get 36. / Your problem should look like: 36 = 12a
Eighth, divide both sides by 12. / Your problem should look like: \frac{36}{12} = a
Ninth, since 3 goes into 12 to get 36, simplify \frac{36}{12} to 3. / Your problem should look like: 3 = a
Tenth, switch sides. / Your problem should look like: a = 3

Answer: a = 3 (one solution)

Show that if u+v and u-v are orthognal, then the vectors u and v must have the same length.
pashok25 [27]

Answer with Step-by-step explanation:

We are given that

u+ v and u-v are orthogonal

We have to prove that u and v must have the same length.

When two vector a and b are orthogonal then

a\cdot b=0

By using the property

(u+v)\cdot (u-v)=0

We know that

(a+b)\cdot (a-b)=\mid a\mid^2-\mid b\mid^2

\mid u\mid ^2-\mid v\mid^2=0

\mid u\mid^2=\mid v\mid^2

Magnitude is always positive

When power of base on both sides are equal then base will be equal

Therefore,

\mid u\mid=\mid v\mid

Hence, the length of vectors u and v must have the same length.
