Andrew [12]

Answer:

2(b+1+b)= 18

Step-by-step explanation:

Perimeter of a rectangle= 2(l+b)

18 feet= 2(l+b)

length: l, breadth: b

Because the length of the sandbox is 1 foot longer, it will be:

b+1 = l

Substitute l with b+1

2(b+1+b)= 18

What is the approximate distance between the points (-5, 1) and (-2, 3) on a coordinate grid? A.7.81 units B.3.61 units C.2.23 u

andrey2020 [161]

The formula for distance between point in a coordinate grid is the following:

$\sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2} }$
Where 1 and 2 stands for the points, so in your case the formula is the following
$\sqrt{( - 2 - - 5) {}^{2} + (3 - 1) }$
$\sqrt{ {3}^{2} + 2 {}^{2} }$
$\sqrt{9 + 4}$
$\sqrt{13} =3.605...$
So your answer is about 3.61
