Answer:
11.2 mm
Explanation:
Given a right angle triangle, In order to find the third side: Use Pythagoras Theorem: a² + b² = c²
Insert Values:
x² + 3.8² = 11.8²
x² + 14.44 = 139.24
x² = 139.24 - 14.44 (subtract)
x² = 124.8
x = √124.8 (square root)
x = 11.1714 ≈ 11.2 (rounded to 3 significant figures)
A=p(1+i/m)^mn
A=11,700×(1+0.039÷4)^(4×18)
A=23,527.94
zero
double - is actually plus

Equation for Perimeter of a rectangle: Perimeter = 2W + 2L
<h3>Defining the variables, let</h3>
<h3>Width = x</h3><h3>Length = 2x+3 (3 more than twice the width)</h3>
<h3>Plugging everything into the equation</h3>
<h3>30= 2(x) + 2(2x+3) using the distributive property,</h3>
<h3>30=2x+4x+6 combining like terms</h3>
<h3>30=6x+6 subtracting 6 from both sides,</h3>
<h3>24=6x divide both sides by 6</h3>
<h3>4=x This means that the width is 4 m.</h3>
<h3>To get the length, use the expression L=2x+3 and plug in x = 4 that was already solved for</h3>
<h3>L=2(4)+3</h3>
<h3>L=8+3 = 11 m</h3>
<h3>So the dimensions of the rectangle are width is 4 m and length is 11 m.</h3>
