Hello, just need the answer for this question. Thank you for your help if you do so.

Mathematics

Answer:

In the first one you are missing (x - 3) so it will be 4(x - 3) and if you factor it out it will be 4x - 12

In the second one you are missing a (x -5)which means 9x(x -5) or when you factor it out it will be 9x^2 - 45x

Step-by-step explanation:

3x^2 -23x + 40 = (3x - 8) (x - 5)

3x^2 -17x + 24 = (3x -8) ( x - 3)

Crank

add the volume of a cone, V=1/3 pi times radius squared times h. The volume of the cone is V=355. Then you add the volume of the cone to the volume of the cylinder. the formula for the volume of a cylinder is V= pi times radius squared times h. So the volume of the cylinder will be V=923. if you add those two together the overall volume is 1,278.

The system of equations below is consistents with infinity many solutions where a and b are constants.Find the values of a and b
Kitty [74]

Answer:

The values of a and b so that the two linear equations have infinite solutions are 3 and \frac{3}{2}, respectively.

Step-by-step explanation:

Two linear equations with two variables have infinite solution if and only if they are<em> linearly dependent</em>. That is, one linear equation is a multiple of the other one. Let be the following system of linear equations:

2\cdot x + y = 6 (1)

a\cdot x + b\cdot y = 9 (2)

The following condition must be observed:

r = \frac{a}{2} = \frac{b}{1} = \frac{9}{6} (3)

After some quick operations, we find the following information:

r = \frac{3}{2}, a = 3, b = \frac{3}{2}

The values of a and b so that the two linear equations have infinite solutions are 3 and \frac{3}{2}, respectively.

BRAINLIEST if right!
FromTheMoon [43]
Alright, so we know that 1 inch is 16 feet on the model. The model that we have is 11.5 inches in length.

To figure this out, simply multiply 11.5 by 16, which equals 184.

This gives us a ratio of 11.5 : 184, which is the same as 1 : 16. You can also write proportions as fractions, so 11.5 / 184 and 1/16 are the same, both equaling 0.0625.

The final answer is 184 ft
