Simplify the expression to a polynomial in standard form: (4x+5) (x^2-3x-2) PLEASE HLEP

pickupchik [31]

Answer:

$4x^3-7x^2-23x-10$

Step-by-step explanation:

So we have the expression:

$(4x+5)(x^2-3x-2)$

Distribute. Multiply (4x+5) to each term:

$(x^2)(4x+5)+(-3x)(4x+5)+(-2)(4x+5)$

Distribute:

$=(4x^3+5x^2)+(-12x^2-15x)+(-8x-10)$

Combine like terms:

$=(4x^3)+(5x^2-12x^2)+(-15x-8x)+(-10)$

Add and simplify:

$=4x^3-7x^2-23x-10$

And this is in descending order, so it's in standard form.

If sin42 degrees = 2/3 then cos48 degrees = what? If tan20.5= 3/8, the tan69.5= what?

Anna11 [10]

Big ifs, question writers. These are of course approximations.

The "co" in cosine comes from complementary angles. It means since

$42^\circ + 48 ^\circ = 90^\circ$

$\sin 42^\circ = \cos 48^\circ$

Answer: cos 48° = 2/3

Similarly,

$20.5^\circ +69.5^\circ = 90^\circ$

$\tan 69.5^\circ = \cot 20.5^\circ = \dfrac{1}{\tan 20.5^\circ} = \dfrac 8 3$

Answer: tan 69.5° = 8/3

Use the diagram to complete the statement. CF =

kondor19780726 [428]

Answer:

∠ECF = 37°

Step-by-step explanation:

∠ACG = 37° because it is a complementary angle to 53° (37° + 53° = 90°)

∠ECF = 37° because it is a vertical angle to 37°

Work out the volume of a cuboid 2cm by 4cm by 5cm

andrew-mc [135]

For a cuboid's volume you simply go length x width x heigth so 2x4x5 so it's 40.
