Answer:
PQ = 18
Step-by-step explanation:
If R is the midpoint of PQ, then PR = RQ
⇒ 6x + 7 = 3x + 8
⇒ 3x = 1
⇒ x = 1/3
So PR = 6x + 7 = 6(1/3) + 7 = 9
and RQ = 3x + 8 = 3(1/3) + 8 = 9
⇒ PQ = PR + RQ = 9 + 9 = 18
F(-5) = 6(-5)^3 + 24(-5)^2 - 24(-5) + 5 = 0
so x = -5 is one zero.
The correct answer is the fourth one 324\pi cm3
Answer:
$95.17
Step-by-step explanation:
If in triangles ABC and DEF, AB = DE, AC = DF, and angle A = angle D, then triangle ABC is congruent to triangle DEF. Using words: If 3 sides in one triangle are congruent to 3 sides of a second triangle, then the triangles are congruent.
