Answer:

\boxed{ \bold{ \boxed{ \sf{12 {x}^{2}  - 13x - 14}}}}

Step-by-step explanation:

\sf{(3x + 2)(4x - 7)}

Use the distributive property to multiply each term of the first binomial by each term of the second binomial

\longrightarrow{ \sf{3x(4x - 7) + 2(4x - 7)}}

\dashrightarrow{ \sf{12 {x}^{2}  - 21x + 8x - 14}}

Collect like terms

\longrightarrow{ \sf{12 {x}^{2}  - 13x - 14}}

Hope I helped!

Best regards! :D

Answer:

12x^{2}  + 29x - 14

Step-by-step explanation:

(3x+2)(4x-7)

Multiply out 3x first then 2

(3x * 4x) - (3x * -7) + (2 * 4x) + (2 * -7)

12x^{2} - (- 21x) + 8x + ( -14)

12x^{2} + 21x + 8x - 14    Combine like terms

12x^{2}  + 29x - 14

three cones have a volume of 192π cm³.Cone A has a radius of 2 cm. Cone B has a radius of 3 cm. Cone C has a radius of 4 cm. fin
andrew11 [14]

9514 1404 393

Answer:

  A: 144 cm

  B: 64 cm

  C: 36 cm

Step-by-step explanation:

The volume of a cone is given by ...

  V = (1/3)πr²h

Solving for h, we get ...

  3V/(πr²) = h

Filling in the given values, we get ...

  3(192π)/(πr²) = h

  576/r² = h

Then the heights of the different cones are ...

  A: r = 2, h = 576/4 = 144 . . . cm

  B: r = 3, h = 576/9 = 64 . . . cm

  C: r = 4, h = 576/16 = 36 . . . cm

Which equation has a slope of –3/2 and a y-intercept of 5?
Natasha_Volkova [10]
I’m not sure what you’re options are but an equation in Y=mx+b form for this would be y= -3/2x + 5

M is always the slope
B is always the y intercept

A 24 foot ladder is placed against a building at an angle of 75⁰. How far is the bottom of the ladder from the building?
yanalaym [24]
24ft is the hypotenuse, at an angle of 75<span>⁰, and we need to find the adjacent.

We use cos(), which is adjacent divided by hypotenuse.

Therefore, we can find the adjacent by doing:

25 * cos(75) = 6.47ft

Round the answer however you like.</span>

A low P-Value in ANOVA table mean that the population mean of each treatment effects are different. the population mean of at le
Verizon [17]

Answer:

The population mean of at least one treatment effect are different.

Step-by-step explanation:

An analysis of variance (ANOVA) is conducted in order to determine if there are significant differences between the values of the population mean with respect to the response variable for the domains that under the effects of different treatments. A low p-value leads to reject the null hypothesis of the following hypothesis system:

H_0: \mu_1=\mu_2=...=\mu_k\\\\\\H_a: \mu_i \neq\mu_j, for $ for some i, j between 1 and k.$

Rejecting H0 means that this hypothesis is false and, in turn, allows us to conclude that the population mean of one of the domains is different from the others.
