Answer:

A. (2+4)² +(5-8)²

Step-by-step explanation:

To find then distance between two points, we will follow the steps below;

write down the formula

D = √(x₂-x₁)²+(y₂-y₁)²

(-4, 8)

x₁=-4

y₁ = 8

(2,5)

x₂=2

y₂=5

we can now proceed to insert the values into the formula

D = √(x₂-x₁)²+(y₂-y₁)²

   

   = √(2+4)²+(5-8)²

    =√(6)² + (-3)²

   =√36+9

   =√45

Therefore the expression which gives the distance between two the two points is  (2+4)² +(5-8)²

1. The sum of a two-digits number is 13. The tens digit is 8 less than twice the units digit. What is the number?
alexgriva [62]

Answer:

<u>The number is 67</u>

Step-by-step explanation:

<u>Equations</u>

Let's consider the number 83. The tens digit is 8 and the unit digit is 3. Note the tens digit's addition to the number is 80, and the unit's addition is 3. This means the tens digit adds 10 times its value, that is, 83 = 8*10 + 3.

Now, let's consider the number ab, where a is the tens digit, and b is the unit digit. It follows that

Number=10*a+b

The question gives us two conditions:

1) The sum of a two-digits number is 13.

2) The tens digit is 8 less than twice the units digit.

The first condition can be expressed as:

a + b = 13                     [1]

And the second condition can be written as:

a = 2b-8                      [2]

Replacing [2] into [1], we have:

2b-8 + b = 13

Operating:

3b = 13 + 8

3b = 21

Solving for b:

b = 21 / 3 = 7

Substituting into [2]:

a = 2*(7) - 8 = 6

Thus, the number is 67

Evaluate z + 2+ z for x = 2, y=-3, z = -4.
Artyom0805 [142]

Answer:

-6

Step-by-step explanation:

Are you sure that z + 2+ z is correct?  x and y do not appear here.

z + 2+ z simplifies to 2z + 2, and so, if z = -4, z + 2+ z has the value

2(-4) + 2, or -6.
