What is the value of 3n + 1 when n = 4?

13

Step-by-step explanation:

Equation:

3n + 1

Let's substitute 4 into the equation as n.

3n + 1

3(4) + 1

Solve:

3(4) + 1

Multiply:

3(4) + 1

12 + 1

Add:

12 + 1

= 13

Therefore, the value of the expression is 13.

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)
