Answer:
2(x-1)(x-4)
Step-by-step explanation:
Begin by dividing each term by 2 and pulling the 2 to the front.
This is a trinomial. Trinomials are three term algebraic expressions typically featuring variables to exponent powers. To break these trinomials down we factor them using the diamond method or GCF. The diamond method states that for a trinomial multiply a*c then find two numbers which multiply to this number and add to b. When you find those numbers, write them as .
a=1, c=4
ac=4 and add to b=-5 which -1 and -4 satisfy
The factored form is 2(x-1)(x-4).
So to rearrange it in the form of y=Mx+b
x-y=-1
if you shift over the X you get
-y=-x-1
now we want y coefficient to be positive as that's the general form.
divide the whole equation by-1
y=X+1
intercept is 1 then
Answer:
value of gold is $33.17
Step-by-step explanation:
given data
depth d = 3800 m = 3.8 km
area A = 3.63 × 10^8 km²
average concentration = 5.8 × 10^−9 g/L
price of gold = $129.00 / troy oz
to find out
value of gold
solution
first we find volume that is
volume v = A× d
put here value
volume = 3.8 × 3.63 × 10^8
volume = 13.794 × km³
volume = 137.94 × L
so mass = 5.8 × × 137.94 ×
mass = 8 × g
mass = 0.2572 troy oz
here we know 1 troy oz = 31.1 g
and we know 1 troy oz = $129
so 0.2572 troy oz = 129 × 0.2572
0.2572 troy oz value is $33.17
value of gold is $33.17
