Find the distance between the points (6,5√5) and (4,3√2).<br> 2, 2√2, 2√3

FromTheMoon [43]

Answer:

D= $\sqrt{(147-30\sqrt{10}}$

Step-by-step explanation:

Here we are required to find the distance between two coordinates. We will use the distance formula to find the distance

The distance formula is given as

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Here we are given two coordinates as

$(6,5\sqrt{5} ) , (4,3\sqrt{2} )$

Substituting these values in the Distance formula given above we get

$D=\sqrt{(6-4)^2+(5\sqrt{5} -3\sqrt{2}) ^2}$

$D=\sqrt{(2)^2+(5\sqrt{5})^2+(3\sqrt{2})^2-2*5\sqrt{5}*3\sqrt{2}}\\$

$D=\sqrt{4+125+18-2*15\sqrt{10}}\\D=\sqrt{147-30\sqrt{10}}\\$

Hence this is our answer

4x +3 -x - 2<br><br><br> Please help me I’m stuck

torisob [31]

Answer:4+1=5

Step-by-step explanation:

The reason the answer is 4+1 is because you have to subtract x from 4x causing it to be just 4 and then y I have to subtract 2 from 3 leaving one then you would have to add 4+1 which equals 5

A new neighborhood activity complex is being built in Erie. The perimeter of the rectangular playing field is 448 yards. The len

BARSIC [14]

Answer:

Length = 178 yards and Breadth = 46 yards

Step-by-step explanation:

The perimeter of the rectangular field is 448 yards

Let the width is b and the length of the field is (4b-6) yards

We need to find the dimensions of the playing field. We know that the perimeter of a rectangle is given by :

P = 2(l+b)

ATQ,

[2((4b-6)+b)] = 448

2(5b-6) = 448

5b-6 = 224

5b = 230

b = 46 yards

Length = (4b-6)

= 4(46) - 6

= 178 yards

Hence, the length and breadth of the field is 178 yards and 46 yards respectively.
