Factor completely 5x2 – 50x + 120

Mathematics
1 answer:
zaharov [31]3 years ago
5 0
The answer is 5(x - 4)(x - 6)
 
5x² – 50x + 120 = 5*x² -  5*10x + 5*24
                           = 5(x² - 10x + 24)
                           = 5(x * x - 4x - 6x + 6*4)
                           = 5(x(x - 4) - (6x - 6*4))
                           = 5((x(x - 4) - 6(x - 4))
                           = 5(x - 4)(x - 6)

If a right angled triangle has 3 sides a,b and c when a=3,b=6 ,what is the value of c?​
Nataliya [291]

Answer:

c = 3√5 ≈ 6.708

Step-by-step explanation:

Use the Pythagorean Theorem because this is a right triangle.

a^2 + b^2 = c^2

3^2 + 6^2 = c^2

9 + 36 = c^2

45 = c^2

√45 = c

<u>c = 3√5 ≈ 6.708</u>

IM IN DESPERATE NEED FOR HELP SOMEONE HURRRRYYY
LenaWriter [7]

Answer:

yes, triangle DEF is similar to triangle DBC, BC corresponds to EF, and angle DCB corresponds to angle F.

Step-by-step explanation:

Part A: Angle D is congruent to angle D by the reflexive property. Since line BC is parallel to line EF then angle DCB = angle DFE by corresponding angles.  Hence triangle DEF is similar to triangle DBS by the AA Similarity Postulate.

Part B: BC corresponds to EF because they are in the same order and the triangles listed DEF and DBC

Part C: Angle DCB corresponds to angle F since they are corresponding angles with the two given parallel lines BC and EF.

No, he is not correct. The lines are the same, so there are an infinite number of solutions.

When two lines are parallel, then the solution is empty set.
