Which of the following is the solution set of 18 - 3n + 2 = n + 20 - 4n?

Answers

Answer 1

Answer:

Answer:

The solution set is the set of all real numbers.

Step-by-step explanation:

Solve: $18-3n+2=n+20-4n$

Like terms are those terms which have same variable to the same power:

Combine like terms;

$20-3n=20-3n$

Subtract 20 from both sides we get;

$20-3n-20=20-3n-20$

Simplify:

$-3n=-3n$

Add 3n to both sides we get;

$-3n+3n=-3n+3n$

Simplify:

$0=0$ for all n

Thus, the given system is dependent.

Therefore, the solution set is set of all real numbers.

Answers

Answer:

The correct option is;

C) AA Similarity Postulate

Step-by-step explanation:

The given parameters are;

BE║CD Given

∠A is congruent to ∠A Reflective property

∠ACD is congruent to ∠ABE Corresponding angles formed by parallel lines and a transversal

∠ADC is congruent to ∠AEB Corresponding angles formed by parallel lines and a transversal

ΔABE ~ ΔACD AA Similarity Postulate

When two angles of one triangle are equal to the corresponding two angles of another triangle, given that the third angle of both triangles are also equivalent based on sum of angles of a triangle postulate, the two triangles are said to be similar based on Angle-Angle (AA) Similarity Postulate.

Given the trinomial, what is the value of the coefficient 'B' in the factored form?2x2 + 14xy − 36y2 = 2(x + By)(x − 2y)

B= ____________

Answers

2x2 + 14xy -36y2 = (2x+2By)(x - 2y)
2x2 + 14xy -36y2 = 2x2 -4xy +2Bxy -4By2
2x2 + 14xy -36y2 = 2x2 + (2B-4)xy -4By2
since the coefficient of y2 is equal so
-4B = -36
B = 9
if you want to make sure subs in coeeficient of xy by B=9
and you'll get 14 so the answer is right
B=9

Answer:

the answer is B=9 i think

What is the value of x y and z below?

Answers

Answer: Y=76 X=104 Z=104

Step-by-step explanation:

The degree 76 and y are both equal so you add it and it is 152.

Then subtract 360-152 to get 208 and since X and Z are equal you divide and get 104.
