Answer:

p(x) = x² - 2x -8

Step-by-step explanation:

We need to find the quadratic equation with roots 4 and -2 , we know that if a and ß are the roots of equⁿ , then the polynomial is ,

[tex]\implies p(x) =k[ x^2-(\alpha + \beta)x+\alpha\beta] [/tex]

Where k is constant . Substitute respective values ,

=> p(x) = k [ x² - ( a + ß )x + aß ]

=> p(x) = k [ x² - ( 4-2) x + (4)(-2) ]

=> p(x) = k [ x² -2x - 8 ]

If k = 1 ,

=> p(x) = x² - 2x - 8

Answer and Step-by-step explanation:

The volume would be 120, which isn't anything of the options listed.

This is because to find the volume of a cube, you multiply the base times the width times the height.

Answer:

Okay first I'll reply to the question one. If x is 2 and there's 12x, you need to multiply 12 by 2 and the reply is 24. For the y, it's almost the same thing, you multiply 3 by 2. The final reply is 24 for x and 6 for y. For the second answer it's the same principe,  if s = 2 and in the equation is 4s, you just need to do 2 multipliate by 4. So at least, the reply is 8 for the var s. For the p, the answer is 24 because, 8 multipliate by 3 is 24. Finally for the g, you just need to multiply 4 and 16 and the reply is 64. So the final answer of your second question is 8+24+64.

Answer: Angle 5

Step-by-step explanation:

The transversal is the line in between the two angles, and they are interior as they are inside two other lines, they are also alternate, thereby making them alternate interior angles.

Answer: 5

hope this helps be nice if its wrong <3

Using the "slope-intercept" form of the line's equation (y = mx + b), you solve for b (which is the y-intercept you're looking for). Substitute the known slope for m, and substitute the known point's coordinates for x and y, respectively, in the slope-intercept equation. That will let you find b.

Hope that helps!!!!

Answer:

it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis.

Answer:

I think that Aliya is paid 3 dollars more than Eric per hour .

a number is divisible by 3 if the sum of its digits is divisible by 3. 375, for instance, is divisible by 3 since sum of its digits (3+7+5) is 15. And 15 is divisible by 3. 1+2=3 and 3 is divisible by 3

Answer: [tex]412000000\ cm^3[/tex]

Step-by-step explanation:

Given

Number is [tex]412\ m^3[/tex]

we know

[tex]1\ m=100\ cm\\\\\therefore 1\ m^3=1000000\ cm^3[/tex]

For [tex]412\ m^3[/tex] it is

[tex]\Rightarrow 412\ m^3=412\times 1000000=412000000\ cm^3[/tex]

Answer:

the angle sum of quadrilateral is 360 degree

x+2x+3x+4x = 360

10x=360

x= 360/10

x= 36

1 angle= 36

2 angle= 2*36=72

3 angle =3*36=108

4 angle= 4*36= 144

Step-by-step explanation:

Answer:

x = 138° because they are alternate interior angles. Alternate interior angles are congruent.

Answer:

[tex]\frac{8}{21}[/tex]

Step-by-step explanation:

[tex]\frac{2}{7}[/tex] ÷ [tex]\frac{3}{4}[/tex]

to divide fraction, take the reciprocal of the second fraction and multiply it by the first fraction:

[tex]\frac{3}{4} = \frac{4}{3}[/tex]

[tex]\frac{2}{7}[/tex] × [tex]\frac{4}{3}[/tex]

multiply like normal:

[tex]\frac{2}{7}[/tex] × [tex]\frac{4}{3}[/tex] = [tex]\frac{8}{21}[/tex]

Answer:

8/21

Step-by-step explanation:

2/7 * 4/3 = 8/21

Answer:

y= -5

Step-by-step explanation:

-3(4) +9y = 57

-12 + 9y = 57

-12 + 12 + 9y = 57 + 12

9y/9 = -45

y= -5

Answer:

D=121

Step-by-step explanation:

First fin the angles on the inside using the outer angles. Always use 180 as your main number to subtract from. 180-131 = 49  180-108= 72   72+49=121

180-121=59  180-59=121

Or an easier way is to see if your outer angles equal up to 360

So 131+108=239

360-239=121

And there's your solution.

Answer: 2 bags

Step-by-step explanation:

First find the area of the yard.

The area given the units would be:

= Length * Width

= 45 * 55

= ‭2,475‬ ft²

Victor needs enough fertilizer to cover ‭2,475‬ft² but each bag covers only 1,250 ft².

The number of bags needed is therefore:

= ‭2,475‬ / 1,250

= 1.98

= 2 bags

Answer:

The area of the regular nonagon is 7921.8 square inches.

Step-by-step explanation:

Geometrically speaking, the area of a regular polygon is determined by following area formula:

[tex]A = \frac{p\cdot a}{2}[/tex] (1)

Where:

[tex]A[/tex] - Area of the regular polygon, in square inches.

[tex]p[/tex] - Perimeter, in inches.

[tex]a[/tex] - Apothem, in inches.

If we know that [tex]p = 162\,in[/tex] and [tex]a = 97.8\,in[/tex], then the area of the regular nonagon is:

[tex]A = 7921.8\,in^{2}[/tex]

The area of the regular nonagon is 7921.8 square inches.

Step-by-step explanation:

12.3(6) + 11.5(7)

73.8 + 80.5 = 154.3
