Simplify -2x x 3x x -x
Answers
Answer:
2x
Step-by-step explanation:
i think this is correct, I'm not 100% sure that it is because the question was a little confusing.
ANSWER:
It would be 6x^3.
PRIOR NOTE:
For this question, it's slightly unclear regarding the formatting with it, but in here I'm going to assume that you've asked what is:
-2x * 3x * -x
when simplified. If it was something else, then the final answer would be different.
BACKGROUND:
To start, when multiplying two terms together, the variable will become squared or to the second power. For example:
2x * 2x = 4x^2
PROCESS:
With this question, it is asking for -2x * 3x * -x, though lets just start with the -2x * 3x part:
-2x * 3x = -6x^2
Now, finishing it off with the * -x part.
-6x^2 * -x = 6x^3
It goes to the third power, because now you have multiplied 3 x's together. The answer is also now positive since a negative * a negative = a positive.
With this, the final answer is 6x^3.

y=x/4+1/2 find the x and y Pls help asap
Answers
Answer:
y = 1/4x + 1/2 and x = -2 +4y
Step-by-step explanation:
Solving it in a way that x/4 is a fraction and not division so you would make that 1/4x. y = x/4 +1/2 x/4 is 1/4x so then you subtract 1/2 from both sides to get y - 1/2 = 1/4x. You can then divide 1/4 on both sides. -1/2 divided by 1/4 is -2 and 1/4y. This will get your answer of x = 1/4y -2 for x. Y is just 1/4x + 1/2

In which set do all of the values make the inequality 3x-7_>11 true? {6,11,15} {0,7,12} {−2,3,6} {−5,0,5}
Answers
Answer:
{6, 11, 15}
Step-by-step explanation:
Given the inequality expression 3x-7≥11
Add 7 to both sides
3x-7+7≥11+7
3x ≥ 18
Divide both sides by 3
3x/3 ≥ 18/3
x≥6
Hence the solution to the inequality are the values of x greater than or equal to 6. Hence the required solutions are {6, 11, 15}

All together Maria and Nick had $12. After Maria spent 30% of her money and Nick spent 50 % of his money, Maria and Nick were left with the same amount. How much money did Nick have to begin with?
Answers
Answer:
$4.5
Step-by-step explanation:
Let the amount of money
Maria had = x
Nick had = y
All together Maria and Nick had $12.
= x + y = 12
x = 12 - y
After Maria spent 30% of her money and Nick spent 50 % of his money, Maria and Nick were left with the same amount.
30% of x = 50% of y
30/100 × x = 50/100 × y
0.3x = 0.5y
We substitute 12 - y for x above
0.3(12 - y) = 0.5y
3.6 - 0.3y = 0.5y
3.6 = 0.5y + 0.3y
3.6 = 0.8y
y = 3.6/0.8
y = $4.5
Therefore, in the beginning, Nick originally had $4.5
Identify the solution(s) of t2+15t=−36.
Answers
Answer:
i solved for t and got
t= -3, -12
Step-by-step explanation:
Answer:
t = - 12, t = - 3
Step-by-step explanation:
Given
t² + 15t = - 36 ( add 36 to both sides )
t² + 15t + 36 = 0 ← in standard form
(t + 12)(t + 3) = 0 ← in factored form
Equate each factor to zero and solve for t
t + 12 = 0 ⇒ t = - 12
t + 3 = 0 ⇒ t = - 3

ASA
Step-by-step explanation:
The ASA (angle side angle) identity states that if 2 triangles share 2 angles and one side in between the angles with each other, they are congruent. Since that is the case here, it is the answer.
Answer:
ASA
Step-by-step explanation:
When you have 2 angles and a side, look and see if the side is between the 2 angles. What that means is that both angles share the one side.
If that happens, then the solution to congruence is ASA. I'd be very careful about using SSA. There are exceptions and you should not choose it if you have a choice. Sometimes it works and sometimes it does not.

Sylvie bakes 4 trays of muffins. Each tray contains 8 muffins. She gives away 12 muffins to friends.
Let m represent the number of muffins Sylvie has left.
Which equation could be used to find the value of m?
4×8−12=m
4 + 8 + 12 = m
4 × 8 + 12 = m
4+8−12=m
Answers
Answer:
4x8-12
Step-by-step explanation:
If she had 4 trays and EACH had 8 muffins you would multiply. So 32 muffins in total, but when you take away which is subtraction, it would be the value of m which is 32-12 and you would get 20 muffins left.
