Given equation is :
=0
Taking out
common we get,
=0
Now solving this we get,
As 11 is not factor-able, we will solve it using the formula,

a=1 b=5 and c=-11
we get,
and 
Answer:
upward?

Answer:
No
Step-by-step explanation:
1.2/3 =0.4
4/5 can be written as 0.8
So, 1.8/0.8 = 2.25.
However, 1.8/4/5 is the same as:
1.8/1 ÷ 4/5
Keep Change Flip
1.8/1 x 5/4 = 9/4
(1.8 x 5=9 & 1 x4 =4)
9/4 =2.25
For a function, if it has an inverse function, keep in mind that, the "domain of the original, is the range of the inverse, and the range of the original, is the domain of the inverse", what the dickens does that mean?
well, it means the values for "x" and f(x), on the inverse, are the same values, but swapped up, therefore
Answer:
25:64
Step-by-step explanation:
surface : 4×pi×R^2
R1 = 5x
R2 =8x
4piR1^2 / 4piR2^2 = R1^2/R2^2 = 5x^2/8x^2 = 25x^2/64x^2 = 25/64
