Answer:

3\sqrt{5}

Step-by-step explanation:

View the distance as a hypotenuse of a triangle ΔABC (∠C = 90°).

Use Pythagorean theorem:

AB = y1 - y2 = 9 - 6 = 3

AC = x1 - x2 = 4 - (-2) = 6

Now calculate BC which is also the distance needed:

BC^{2} =AC^{2} +AB^{2}

BC^{2} = 6^{2} + 3^{2} = 45

BC = \sqrt{45} = \sqrt{3 * 3 * 5} (BC > 0)

BC = 3\sqrt{5}

Urgent help!!!<br> I'll choose brainlest!<br> Plsss
kipiarov [429]
A) volume equals = length x width x height
2.8m is the height
1.2m is the width
4.8m is the length
so 2.8m x 1.2m x 4.8m = 16.128m³  is your answer
b)1 cubic meter is 1000
2.8m = 2800L
1.2m = 1200L
4.8m = 4800L
so your going to add those up
2800L + 1200L + 4800L = 8800L  is you answer

-4(3x-1)=12-8x and plz show how you got it
Inga [223]
Step 1:  -4(3x-1) becomes -12x+4
step 2: -12x+4=12-8x
step 3: add 12x to both sides, 4=12+4x
step 4: subtract twelve from both sides -8=4x
step 5: divide by 4, x=-2
