2/5 = 6/15 = 12/30 = 14/35 = 16/40
0.2/0.5 = 1.2/3 = 8/20 = 0.8/2 = 10/25
hope this helps! :)
Answer:
36
Step-by-step explanation:
Givens
a = 312
d = -6
n = 47
Formula
L_n = a + (n - 1)*d
Solution
L_n = 312 + (47 - 1) * -6
L_n = 312 + 46*(-6)
L_n = 312 - 276
L_47 = 36
If it has rational coefients and is a polygon
if a+bi is a root then a-bi is also a root
the roots are -4 and 2+i
so then 2-i must also be a root
if the rots of a poly are r1 and r2 then the factors are
f(x)=(x-r1)(x-r2)
roots are -4 and 2+i and 2-i
f(x)=(x-(-4))(x-(2+i))(x-(2-i))
f(x)=(x+4)(x-2-i)(x-2+i)
expand
f(x)=x³-11x+20
<h2>(3x+4)+2(3x+4)=117</h2>
<h2>= (3x+4)+(6x+8)=117</h2><h2>= 3x+4+6x+8=117</h2><h2>= 9x+12=117</h2><h2>= 9x = 117-12 </h2><h2>= 9x = 105</h2><h2>= x =105 ÷ 9</h2><h2>= x = 11.6666666667</h2>
<h2>Hence,x = 11.6666666667</h2>
