Answer:

The lengths of the sides are 15 cm , 17 cm and 19 cm.

Step-by-step explanation:

Step 1. Perimeter P means adding up all three sides.


Step 2. Let n be an odd integer.


Step 3. Let n+2 and n+4 be the next two consecutive odd integers.


Step 4. Then P=n+n+2+n+4=51.


Step 5. Solving the equation Step 4 yields the following steps


3n%2B6=51


Subtract 6 from both sides of the equation


3n%2B6-6=51-6

3n=45


Divide 45 to both sides of the equation


3n%2F3=45%2F3


n=15 Then n%2B2=17 and n%2B4=19. Also, P=15+17+19=51 which is a true statement.


Step 6. ANSWER: The lengths of the sides are 15 cm , 17 cm and 19 cm.

When lines are parallel...
Otrada [13]

Answer:

1) Congruent

2) Supplementary

3) Congruent

4) Congruent

Step-by-step explanation:

1) The Alternate Interior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent .

2) Formally, we can say that if two lines are parallel, then consecutive interior angles are supplementary. We refer to this as the consecutive interior angles postulate.

3) When the lines are parallel, the corresponding angles are congruent . When two lines are cut by a transversal, the pairs of angles on one side of the transversal and inside the two lines are called the consecutive interior angles.

4) The Alternate Exterior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate exterior angles are congruent.

G(x) = x^2 + 2x + 6
g(x) = x^2 + 2x + 1 + 5
g(x) = (x+1)^2  + 5

so
f(x) = x^2 to g(x) = (x+1)^2  + 5
shifted to the left 1 unit and up 5 units

answer is A. left 1 unit and up 5 units
