1/6^8 or 1/1679616. The negative 3 becomes a positive 3 in the denominator
(4x^2-25)/(2x-5)=14
we hates fractions so m ultiply both sides by (2x-5)
4x^2-25=14(2x-5)
4x^2-25=28x-70
add 70 to both sides
4x^2+45=28x
subtract 28x fromoth sides
4x^2-28x+45=0
use quadratic formula which is
if you have
ax^2+bx+c=0 then
x=
a=4
b=-28
c=45
subsitute
x=
x=
x=
x=
or
if we were to put 5/2 for x, the deonomentor would be equal to zero, so it cannot be used
answer is
x=9/2
2fg+4g-6fg
(MINUS 6fg from 2fg)
-4fg+4g
(i would then put 4g- the common factor- outside brackets like)
4g(-f+1)

Answer:
The expression representing Area of garden is.
Step-by-step explanation:
Given:
Width of garden =
the length of the garden is 1 foot longer than the width
Hence length of garden =
We need to find the expression for area of garden.
Area of rectangular garden can be calculated as length times width.
Framing in equation form we get;
Area of Garden =
Solving the equation we get;
Area of Garden =
Hence The expression representing Area of garden is.
Answer:
