Which is an example of a quadratic trinomial ​

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:

y= -5

Step-by-step explanation:

-3(4) +9y = 57

-12 + 9y = 57

-12 + 12 + 9y = 57 + 12

9y/9 = -45

y= -5

C is the  answer

Step-by-step explanation:

The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. The measure of side DE is 12.3.

The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. It is given by the formula,

[tex]c =\sqrt{a^2 + b^2 -2ab\cdot Cos\theta}[/tex]

where

c is the third side of the triangle

a and b are the other two sides of the triangle,

and θ is the angle opposite to the third side, therefore, opposite to side c.

In the given triangle the length of the side DE can be found using the law of cosine. Therefore, the length of the side DE can be written as,

DE² = DF² + EF² - 2(EF)(DF)(Cos 59°)

DE² = 144 + 169 - 2(12 × 13 × Cos 59°)

DE² = 144 + 169 - 160.6918

DE² = 152.30812

DE = 12.3413 ≈ 12.3

Hence, the measure of side DE is 12.3.

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:

35.9 units cubed

Step-by-step explanation:

Hello There!

The figure shown is a rectangular prism

The formula for volume of a rectangular prism is

Length times width times height

The dimensions for the shown figure are given

height = 4 1/2

length = 2 1/8

width = 3 3/4

given this information we just plug it in to the formula

so

[tex]V=3\frac{3}{4}*4\frac{1}{2} *2\frac{1}{8}[/tex]

then we plug it in to a calculator and get that the volume is equal to

35.859375

finally we round to the nearest tenth and get that the volume is equal to

35.9 units cubed

Answer:

A Luis le quedan 70 kg de patatas.

Step-by-step explanation:

Para encontrar la respuesta, primero tienes que determinar la cantidad total de patatas que Luis ha vendido multiplicando la cantidad de kilos en cada bolsa por el número de bolsas vendidas:

2,5kg*10=25 kg

Ahora que sabes que Luis ha vendido 25 kg de patatas puedes restar esto de la cantidad de kilos que tenía para saber cuánto le queda:

95-25=70

De acuerdo a esto, la respuesta es que a Luis le quedan 70 kg de patatas.

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: 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:

8/13 cups of sugar

Step-by-step explanation:

Jamal is baking 4 batches of chocolate chip cookies. He needs 2 13 cups of sugar for each batch. Which expression could be used to determine the total amount of sugar that Jamal needs?

For the above question

1 batch of chocolate chips cookies = 2/13 cups of sugar

4 batches = x

Cross Multiply

x = 4 × 2/13 cups of sugar

x = 8/13 cups of sugar

Answer:

W = 6.75

L = 20.25

Step-by-step explanation:

2(w + 3w) = 54

8w = 54

w = 6.75

L = 20.25

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.

Formula for SA of a rectangular prism: [tex]SA = 2(lw + lh + wh)[/tex]

Plug in length, width, and height

[tex]SA = 2((4.2)(14.1)+(4.2)(9)+(14.1)(9))[/tex]

[tex]SA = 447.84[/tex] ft

48+140=188

92+210=302

if you at all it equals 490

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.
