Answer:
n=0
Step-by-step explanation:
Clear parenthesis w/ distribution:
3(-7n+1)=-21n+3
Move everything over to one side:
6n+3=-21n+3
6n=21n Subtract the 3 on the right.
-15n=0 Subtract the 21.
n=0 Divide the -15.
Answer:21
Step-by-step explanation: solve whats in the numerator then solve whats in the denominator then you divide
Answer:
rational algebraic expression
Answer:
The factors of x²-64 is equal to (x-8)(x+8).
Step-by-step explanation:
The given expression is:
x²-64
we know that, 8² = 64
So,
(x²-8²) = (x-8)(x+8) [As (a-b)(a+b) = a²-b²]
So, the factors of x²-64 i equal to (x-8)(x+8).
Answer:
The two column proof is presented as follows;
Statement 
Reason
1. Parallelogram SUPN 
⊥ 
1. Given
and 
⊥
2. ∠SRU = ∠PMN = 90° 2. Definition of perpendicular lines
3. ∠SRU ≅ ∠PMN 2. Definition of congruency
4. 
║ 
4. Opposite sides of a parallelogram are congruent
5. ∠SNR ≅ ∠PUM 5. Alternate interior angles are congruent
6. ≅ 6. Opposite sides of a parallelogram are congruent
7. ΔPMU ≅ ΔSRN 7. By AAS rule of congruency
By the Angle-Angle-Side (AAS) rule of congruency, we have that, if two angles and a corresponding adjacent side (∠SRU ≅ ∠PMN, ∠SNR ≅ ∠PUM, ≅ ) of two triangles (ΔPMU and ΔSRN) are congruent, then the the two triangles are also congruent (ΔPMU ≅ ΔSRN)
