We  know that

in the figure <span>equivalent ratios are
</span>BS/BC
and
AR/AC

therefore

AR/RC is not equivalent

the answer is 
AR/RC

Find all the zeros of the equation 12x^2-64=-x^4
Natalija [7]

Answer: all the zeroes of the above equation will be

(x-4)(x+4)(x-2)(x+2)

Step-by-step explanation:

Since we  have given that

12x^2-64=-x^4\\\\x^4+12x^2-64=0

We need to find the zeroes of the above equation.

So, we will use  "Split the middle terms" :

x^4+12x^2-64=0\\\\x^4+16x^2-4x^2-64=0\\\\x^2(x^2-16)-4(x^2-16)=0\\\\(x^2-4)(x^2-16)=0\\\\x^2-4=0\ or\ x^2-16=0\\\\\text{ "Using }a^2-b^2=(a+b)(a-b)"\\\\x^2-4=x^2-2^2=(x-2)(x+2)\\\\x^2-16=x^2-4^2=(x+4)(x-4)

So, all the zeroes of the above equation will be

(x-4)(x+4)(x-2)(x+2)

Mikela claims that the sum of any two numbers is greater than the larger of the two numbers. Jim claims that the sum of any two
qaws [65]

<u>ANSWER:  </u>

The statement of Jim is correct

<u>SOLUTION:  </u>

Given statements are  

Mikela claims that sum of any two numbers is greater than the larger of the two numbers.  

Jim claims that the sum of any two natural numbers is greater than the larger of the two numbers.

Let a,b be the two numbers and a is the greatest of a and b

According to the mikela statement = a + b > a

b > a – a

b > 0

Here, we got an condition that b > 0, but it may not be true always.  

Above condition fails when b is either 0 or negative number.  

Jim - sum of any two natural numbers is greater than the larger of the two numbers.

Let a,b be the two natural numbers. And a is the greatest of a and b

According to the jim statement  =  a + b > a

b > a – a

b > 0

Here, we got an condition that b > 0,

And this statement will always be true because b is an natural number, so it will be greater than 0.

Hence jim’s statement is true.

sarah has a solid wooden cube with a length of 4/5 centimeter. from eaxh of its 8 corners, she cuts out a smaller cube with a le
faltersainse [42]
First, calculate for the volume of the cube before each edges are cut.
                                    V = e³
where e is the length of each sides. Substituting the known value,
                                   V = (4/5 cm)³ = 0.512 cm³

Then, calculate for the volume of each of the small cubes cut out from the corners.
                                   V = (1/5 cm)³ = 0.008 cm³
Since there are 8 of these small cube, we multiply the volume by 8.
                                       8V = 8(0.008 cm³) = 0.064 cm³

Then, subtracting the volumes will give us an answer of <em>0.448 cm³</em>
