Hello,

6x²-5x-56=0
==>6x²-21x+16x-56=0
==>3x(2x-7)+8(2x-7)=0
==>(2x-7)(3x+8)=0
==>x=7/2 or x= -8/3

Consider the given equation 6x^2-5x=56

We have to use the zero product property to evaluate the solutions to the given equation.

The Zero product property states that "The product of factors is zero if and only if one or more of the factors is zero".

Since, 6x^2-5x=56

6x^2-5x-56=0

We will use "middle the splitting term" method to evaluate its solutions.

6x^2-5x-56=0

6x^2-21x+16x-56=0

3x(2x-7)+8(2x-7)=0

(3x+8)(2x-7)=0

Now, by zero product property,

3x+8=0

x=\frac{-8}{3}

or

2x-7=0

x=\frac{7}{2}

So, the solutions are x=\frac{-8}{3} or x=\frac{7}{2}.

A grain silo is built from two right circular cones and a right circular cylinder with internal measurements represented by the
Murljashka [212]

Answer:

Step-by-step explanation: The volume of the grain silo can be found by adding the volumes of all the solids of which it is composed (a cylinder and two cones). The silo is made up of a cylinder (with height 10 feet and base radius 5 feet) and two cones (each with height 5 ft and base radius 5 ft). The formulas given at the beginning of the SAT Math section:

Volume of a Cone:

V=\frac{1}{3} \pi r^2h

Volume of a Cylinder:

V=\pi r^2h

can be used to determine the total volume of the silo. Since the two cones have identical dimensions, the total volume, in cubic feet, of the silo is given by

V_{silo} =\pi (5^2)(10)+(2)(\frac{1}{3})\pi (5^2)(5)=(\frac{4}{3})(250)\pi

which is approximately equal to 1,047.2 cubic feet.

<u>The final answer is D.</u>
