Solving the given equation, the value of v that makes the statement true is:

A. v = 8.

<h3>What is the given equation?</h3>

The equation is:

$12 = 12 + \frac{v - 8}{2}$

Hence:

$\frac{v - 8}{2} = 0$

Applying cross multiplication:

v - 8 = 0

v = 8.

Hence option A is correct.

Use the identity (x+y)(x−y)=x2−y2 to find the difference of two numbers if the sum of the numbers is 12 and the difference of th

Natalka [10]

Answer:

The difference of two numbers using identity $(x+y)(x-y)=x^2-y^2$ is 4.

Step-by-step explanation:

Given: The sum of the numbers is 12 and the difference of the squares of the numbers is 48.

To find the difference of two numbers using identity $(x+y)(x-y)=x^2-y^2$

Let the two numbers be a and b, then

Given that the sum of the numbers is 12

that is a + b = 12 .........(1)

Also, given the difference of the squares of the numbers is 48.

that is $a^2-b^2=48$ ..........(2)

Using given identity $(x+y)(x-y)=x^2-y^2$

We have $(a+b)(a-b)=a^2-b^2$

Substitute the known values, we have,

$12(a-b)=48$

Divide both side 12 , we have,

$(a-b)=4$

Thus, the difference of two numbers using identity $(x+y)(x-y)=x^2-y^2$ is 4.

suppose a triangle has two sides of length 32 and 35, and that the angle between these two sides is 120. what is the length of t

Vesnalui [34]

Using cosine rule, the length of the required side = sqrt(32^2 + 35^2 - 2 x 32 x 35cos 120)
= sqrt(1024 + 1225 - (-1120))
= sqrt(2249 + 1120)
= sqrt(3369)
= 58.04

Ew, mental math... so basically, we would estimate the washing dishes to 20 minutes, and cleaning 40 min,
together 20+40 min

is 60 minutes, aprox 1 hour
