Answer:
Step-by-step explanation:
13-3 = 10
10/5 = 2
2 x 6 = 12
Base=legnth
perimiter=width+width+height+height or
p=2legnth+2h
so if p=132.8
and base legnth=legnth=l=60.2 then
subsitute
132.8=2(60.2)+2h
132.8=120.4+2h
subtract 120.4 from both sides
12.4=2h
divide by 2
6.2=h
the height is 6.2mm
By applying the <em>quadratic</em> formula we conclude that the roots of the <em>quadratic</em> equation y = 2 · x² - 4 · x - 3 are 1 + 0.5√10 and 1 - 0.5√10, respectively.
<h3>How to find the roots of a quadratic equation </h3>
All <em>quadratic</em> equations of the form a · x² + b · x + c = 0 have two roots that can be found by using the <em>quadratic</em> formula:
(1)
If we know that a = 2, b = - 4 and c = - 3, then the roots of the <em>quadratic</em> equations are:
By applying the <em>quadratic</em> formula we conclude that the roots of the <em>quadratic</em> equation y = 2 · x² - 4 · x - 3 are 1 + 0.5√10 and 1 - 0.5√10, respectively.
