Answer:

17 k + -25

Step-by-step explanation:

Simplify the following:

-5 (1 - 5 k) - 4 (2 k + 5)

-5 (1 - 5 k) = 25 k - 5:

25 k - 5 - 4 (2 k + 5)

-4 (2 k + 5) = -8 k - 20:

25 k + -8 k - 20 - 5

Grouping like terms, 25 k - 8 k - 20 - 5 = (25 k - 8 k) + (-5 - 20):

(25 k - 8 k) + (-5 - 20)

25 k - 8 k = 17 k:

17 k + (-5 - 20)

-5 - 20 = -25:

Answer: 17 k + -25

Show that the following statement is an identity by transforming the left side into the right side. sin θ (sec θ + csc θ) = tan

ExtremeBDS [4]

Answer:

Step-by-step explanation:

Required to prove that:

Sin θ(Sec θ + Cosec θ)= tan θ+1

Steps:

Recall sec θ= 1/cos θ and cosec θ=1/sin θ

Substitution into the Left Hand Side gives:

Sin θ(Sec θ + Cosec θ)

= Sin θ(1/cos θ + 1/sinθ )

Expanding the Brackets

=sinθ/cos θ + sinθ/sinθ

=tanθ+1 which is the Right Hand Side as required.

Note that from trigonometry sinθ/cosθ = tan θ
