Here we go!
The quadratic formula: x = [-b ± √(b2<span> - 4ac)]/2a
a = 1 (understood coefficient)
b = 12
c = -13
</span>
Okay, so here, we split into 2 problems. If 14 were positive:
If 14 were negative:
So,
Answer:
4 2/5
Step-by-step explanation:
Answer:
Step-by-step explanation:
Surface area of a triangular prism
Height = 8cm
12cm
10cm
This given as:
S.A = B + Ph
The solutions of x and y?
2x+y=8...(1)
x-2y=-1...(2)
for (2), x=-1+2y...(3)
sub(3) into(1),
2(-1+2y) +y=8
-2+4y+y=8
5y=10
y=2
sub y=2 into(3)
x=-1+2(2) =3
therefore, x=3,y=2
