<h3>Given :</h3>

  • f(x) = 2x - 3

<h3>To Find :</h3>

As, f(x) = 2x - 3

Therefore, f(-2) = 2(-2) - 3

\sf : \implies f(-2) = 2(-2) - 3

\sf : \implies f(-2) =  - 4 - 3

\sf : \implies f(-2) = - 7

<h3>Hence, value of f(-2) is - 7.</h3>

The diagonals of a rhombus have lengths of 12 centimeters and 16 centimeters. what is the length of one side of the rhombus
Yuki888 [10]
<span>Diagonals of a rhombus are perpendicular and bisect each other. This means this rhombus is composed of four right triangles with legs of length 6 cm and 8 cm, with their hypotenuses forming the perimeter of the rhombus. The Pythagorean theorem a^2+ b^2 = c^2 can be used to find the length of the hypotenuse. 6^2+8^2 = 36+64 = 100. The square root of 100 is 10, so the length of a side of the rhombus is 10 cm.</span>
