What is the factored form of x2 – x – 2? (x – 2)(x 1) (x 2)(x 1) (x – 2)(x – 1) (x 2)(x – 1)
Alexxx [7]

A quadratic equation is an equation whose leading coefficient is of the second degree. The factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

<h3>What is a quadratic equation?</h3>

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.

It is written in the form of ax²+bx+c.

The factored form of the quadratic equation can be done in the following manner,

x^2-x-2\\\\= x^2-2x+x-2\\\\=x(x-2)+(x-2)\\\\=(x+1)(x-2)

Thus, the factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

Veronica works at a music store last week she sold five more than three times the number of headphones that she sold this week.
svet-max [94.6K]

Answer:

14 headphones

Step-by-step explanation:

Use algebraic manipulation. Let x be the number of headphones sold this week:

89 = x + (3x + 5)

Combine like terms:

89 = 4x + 5

Get the x's on one side:

84 = 6x

Divide:

14 = x

So, Veronica sold 14 headphones this week.

Please help me this is urgent
ahrayia [7]

Answer:

we know,

area of circle = πr²

area of semicircle of circle having diameter of 16.

according to formula = πr²

radius = 16/2 = 8 cm

22/7 × (8)² → 22/7 × 64 → 1408/7 = 201.14/2 = 100.57 cm (approx.)

area of semicircle of circle having diameter of 20 cm.

22/7 × 20² = 22/7 × 400 = 8800/7 = 1257.14/2 = 628.57

to get the area of shaded part 628.57 - 100.57 = 528 cm² (approx.)

hope this helps you!
