Set f(x) equal to zero and solve. Use the zero product property.

f(x) = 0
(x-9)(x+12)(x-24) = 0
x-9=0 or x+12=0 or x-24=0
x=9 or x=-12 or x=24

The zeros or roots of the polynomial are: 9, -12, 24

How do you simplify this and write as a polynomial in standar form? (x-9)3x-7)+(3x^2-5x+2)

nasty-shy [4]

Answer:

Standard form of $(x-9)(3x-7) + (3x^{2} - 5x+2)$ $=6x^{2} - 39x + 65$

Step-by-step explanation:

Here, the given expression is $(x-9)(3x-7) + (3x^{2} - 5x+2)$

Now, simplifying the above expression in parts, we get

$(x-9)(3x-7) = 3x^{2} - 7x -27x + 63 = 3x^{2} - 34x + 63$

hence, combining both parts:

$(x-9)(3x-7) + (3x^{2} - 5x+2)$ $=(3x^{2} -34x +63) + (3x^{2} - 5x+2)$

= $6x^{2} - 39x + 65$

The above expression is of the STANDARD FORM: $ax^{2} +bx + c$

Hence, the standard form of $(x-9)(3x-7) + (3x^{2} - 5x+2)$ $=6x^{2} - 39x + 65$

To make a specific hair dye, a hair stylist uses a ratio of 1 1/8 oz of red tone, 3/4 oz of gray

nadezda [96]

Answer:

We can call the amounts of red, gray, and brown dye 1 1/8x, 3/4x and 5/8 x respectively and we can write the equation:

1 1/8x + 3/4x + 5/8x = 20

2 1/2x = 20

x = 8 which means that the stylist needs 1 1/8 * 8 = 9 oz red, 3/4 * 8 = 6 oz gray and 5/8 * 8 = 5 oz brown.

Combined, there are Asians, Africans, Europeans, and Americans in a village. The number of Asians exceeds the number of Afric

yanalaym [24]

There are 123 Asians, 25 Africans, 21 Europeans and 8 Americans in the village.

To determine the number of Asians, Africans, Europeans, and Americans in the village, the following calculation must be performed:

A.S + A.F + E.U + A.M = 177
A.S = A.F + E.U + 69
E.U - A.M = 13
E.U = A.M + 13
2A.F = E.U + A.M + 29
A.F + E.U + 69 + A.F + E.U + A.M = 177
A.F + A.M + 13 + 69 + A.F + A.M + 13 + A.M = 177
2A.F + 3A.M = 177 - 13 - 13 - 69
E.U + A.M + 29 + 3A.M = 82
A.M + 13 + A.M + 29 + 3A.M = 82
5A.M = 82 - 13 - 29
A.M = 40/5
A.M = 8
E.U = 8 + 13 = 21
A.F = (21 + 29) / 2 = 25
A.S = 177 - 25 - 21 - 8 = 123

Therefore, there are 123 Asians, 25 Africans, 21 Europeans and 8 Americans in the village.

Solve the system of equations using elimination. SHOW WORK!!!!!!!!!!!!!

irinina [24]

q= 6

r= 7

work--

Multiply 1st column by -2:

-30q+8r=-124

5q+8r=86

Subtract 2nd column from the first column:

-35q= -210

Solve for q:

q=6

Subtract q=6 by any of the two equations, so:

-30q+8r=-124

-30*6+8r=-124

Solve for r:

r=7
