Answer: 9
Step-by-step explanation: Here, we have the expression <em>4x - 7</em> and we want to evaluate the expression when <em>x</em> is equal to 4.
To evaluate an expression, we simply plug the value
of the variable into the expression and solve.
So here, since <em>x</em> is equal to 4, we have 4(4) - 7.
4(4) is equal to 16.
So we have 16 - 7 which is equal to 9.
So the value of our expression when <em>x</em> is equal to 4 is 9.
Answer:
The congruent segments are LN and NK ⇒ C
Step-by-step explanation:
<em>If a line is a perpendicular bisector of another line, that means this line intersects the other line in its midpoint and form right angles around this point</em>
∵ Line JM is the perpendicular bisector of line LK
→ That means JM intersect LK at the midpoint of LK
∵ Line JM intersects line LK at point N
∴ Point N is the midpoint of LK
∵ N divides LK into two segments LN and NK
∵ N is the midpoint of LK
→ That means LN equals NK
∴ LN = NK
∴ The congruent segments are LN and NK
