First we factor out 3a and -4. 3a(2a-5)-4(2a-5) =Now we take out (2a-5) our what’s left in brackets.(2a-5)(3a-4)

Heya!

Here is your answer:

6a²-15a-8a+20


= 3a(2a-5) -4(2a-5)

Answer:

The exact value of tan(M) is 5/12 ⇒ answer (C)

Step-by-step explanation:

* Lets revise the trigonometry functions

- In ΔABC

# m∠B = 90°

# Length of AB = a , length of BC = b and length of AC = c

# The trigonometry functions of angle C are

- sin(C) = a/c ⇒ opposite side to ∠C ÷ the hypotenuse

- cos(C) = b/c ⇒ adjacent side to ∠C ÷ the hypotenuse

- tan(c) = a/b ⇒ opposite side to ∠C ÷ adjacent side to ∠C

* Now lets solve the problem

- In ΔONM

∵ m∠N = 90°

∵ MN = 12

∵ ON = 5

∵ tan(M) = ON/NM ⇒ opposite side of ∠(M) ÷ adjacent side of ∠(M)

∴ tan(M) = 5/12

* The exact value of tan(M) is 5/12

Is this answer correct? Thank you

Your answer is technically correct, but you need to simplify it. Both 12 and 36 can be divided by 12. After doing that you get:
1:3
Also, you need to make sure the order is correct, 1:3 also fixes the order.
