Answer:
106
Step-by-step explanation:
Ok this question is a bit confusing but once you understand the concept you will be able to answer the question correctly
Always know that bracket is solved first once it is found in the question
So back to the question
-4(2-5)2+82
So let's get to work...
Bracket first
-4(-3)2+82
Multiply with the number at the front then followed by the one at the back
(+12)2+82
24+82
106
Therefore the final answer is 106
I believe you understand how we get the answer...just be careful when solving this kind of question... simple

Answer: C) 3</h3>
The rule we'll use is a^b*a^c = a^(b+c). So we add the exponents.
That means 5^n*5^3 = 5^(n+3)
So 5^n*5^3 = 5^6 turns into 5^(n+3) = 5^6
The bases are equal to 5, so the exponents be equal to one another.
n+3 = 6
n+3-3 = 6-3
n = 3
So 5^3*5^3 = 5^(3+3) = 5^6.
Because 6 * 8 + ( - 2 )* 24 = 48 - 48 = 0 , the vectora u and v are orthogonal ;
Two vectors are orthogonal if their dot product is zero.<span />
Answer:
no
Step-by-step explanation:
To determine if (1, 6) is a solution, substitute x = 1, y = 6 into the left side of both equations and if the value obtained equals the right side then it is a solution.
10(1) - 6 = 10 - 6 = 4 ≠ - 6
- 10(1) + 5(6) = - 10 + 30 = 20 ≠ 30
Then (1, 6 ) is not a solution to the system
