Answer:
the shape is semetrical
Step-by-step explanation:
If we were to foil
after experieence
we know
ax²+bx+c=0
and
in form
(ax+b)(cx+d)=0
if we expand it, we get
acx²+bcx+adx+bd=0
or
(ac)x²+(bc+ad)x+(bd)=0
compare to
ax²+bx+c=0
we notice that the middle terms (x terms) are
b=(bc+ad)
so
in form
(2x-1)(1x+5)
b=bc+ad=(-1*1+2*5)=-1+10=9
b=9
or you could just expand it
Answer: See below
Explanation:
Write an equation for nth term:
a + d(n - 1)
a = 8 (first term)
d = -6 (common difference)
8 - 6(n - 1)
= 8 - 6n + 6
= -6n + 14
Find a 50:
-6(50) + 14
= -300 + 14
= -286
You just have to make 36/10 into 3 6/10. After that, it would become 3.6
Answer:
= 12 cm^3
Step-by-step explanation:
V = Bh where B is the area of the base and h is the height
For a triangular prism, the base is the triangle
A = 1/2 bh for the triangle
= 1/2 (6*2)
= 6 cm^2
To find the volume for the triangular prism
V = Bh
= 6 * 2
= 12 cm^3
