Answer:

Box 1 = -4

Box 2 = -3

Box 3 = -5

Step-by-step explanation:

-4x^{2} + 2x - 5(1 + x)

=> -4x^{2} + 2x - 5 - 5x

=> -4x^{2} + (2x + - 5x) -5

=> -4x^{2} - 3x - 5

This equation can no more be divided / simplified, so,

The answer = -4x^{2} - 3x - 5

So, in the boxes, the answer will be,

Box 1 = -4

Box 2 = -3

Box 3 = -5

If my answer helped, kindly mark me as the brainliest!!

Thank You!!

2sin² theta = sin theta for - 270° ≤ 0 ≤180°
sertanlavr [38]

Answer:

θ = 0°

θ = 30°

θ = 150°

θ = 180°

Step-by-step explanation:

2sin² θ = sin θ

Then

2sin² θ - sin θ = 0

Then

sin θ (2sin θ - 1) = 0

Then

sin θ = 0  or  2sin θ - 1 = 0

Then

sin θ = 0  or  sin θ = 1/2

…………………………………………

We have sin θ = 0 and - 270° ≤ θ ≤180°

Then

θ = 0 or θ = π = 180°

On the other hand,

sin θ = 1/2 and - 270° ≤ θ ≤180°

Then

θ = π÷6 or θ = 5π÷6

π÷6 = 30° and 5π÷6 = 150°

Please help!! I'll give 50 points
Scrat [10]

Answer: y=0 and x=3

Step 1: Solve for x in 2x+9y=6.

2x+9y=6

2x=6-9y (Subtract 9y from both sides)

x=3 - 4.5y( Divide both sides by 2)

Step 2: Replace x with 3-4.5y

-7x - 8y = -21\\-7(3-4.5y) - 8y = -21\\

Step 3: Solve for y

(-21)+31.5y-8y=(-21) (By looking at this, we can determine that y=0)

Step 4: Replace y with 0

2x+9y=6\\2x+9(0)=6\\2x=6\\

x=3 (Divide both sides 2)

Therefore, y=0 and x=3
