The zeros of this function is -4 and -8
viktelen [127]3 years ago
3 0

Answer:

Step-by-step explanation:

The given equation is:

f(x)=x^2+12x+32

Simplifying the above expression, we have

f(x)=x^2+4x+8x+32

f(x)=x(x+4)+8(x+4)

f(x)=(x+4)(x+8)

Thus, zeroes of the given function will be:

f(x)=0

(x+4)(x+8)=0

x=-4 and x=-8

Therefore the zeroes of the given function are x=-4 and x=-8.

HELP PLEASE <br><br><br> Simplify.
maksim [4K]
Simplifying
2x + -3(3 * 0.6x + 2.7)

Multiply 3 * 0.6
2x + -3(1.8x + 2.7)

Reorder the terms:
2x + -3(2.7 + 1.8x)
2x + (2.7 * -3 + 1.8x * -3)
2x + (-8.1 + -5.4x)

Reorder the terms:
-8.1 + 2x + -5.4x

Combine like terms: 2x + -5.4x = -3.4x
-8.1 + -3.4x

The local radio tower is located 20 miles east and 12 miles north of Pamela's cabin. The radio tower has a 25 mile broadcast rad
pychu [463]

Answer:

x^2 +y^2 -40x -24y  -81 =0

Step-by-step explanation:

We can write the equation of a circle in the form

(x-h)^2 + (y-k)^2 = r^2

Where (h,k) is the center and r is the radius

Assuming that Pamela's cabin is the center

( x-20)^2 + (y- 12)^2 = 25^2

We want to get to general form

x^2 + y^2 + Dx + Ey + F = 0,

Distributing

x^2 -40x +400 + y^2 -24y +144 = 625

x^2 +y^2 -40x -24y +544 -625 =0

x^2 +y^2 -40x -24y  -81 =0

Show that 6^3-1 is divisible by 5 using our identities
Doss [256]

Answer:

Step-by-step explanation:

a³-b³=(a-b)(a²+ab+b²)

6³-1=6³-1³=(6-1)(6²+6*1+1²)=5×43

so 6³-1 is divisible by 5.
