The gold standard is No longer used by many countries. Therefore, the correct option is option B.
A monetary system known as the "gold standard" links the value of a nation's currency or paper money directly to the price of gold. Countries agreed to exchange paper money for a certain amount of gold under the gold standard. A nation that adheres to the gold standard establishes a fixed gold price and buys and sells gold at that rate.
The value of the currency is established using that set price. The worth of a dollar, for instance, would be equal to 1/500th of an ounce of gold if the U.S. fixed the price of gold at $500 per ounce. The gold standard is No longer used by many countries.
Therefore, the correct option is option B.

Answer:
(x^2+8) ( y+4)
Step-by-step explanation:
x^2y + 8y+ 4x^2 +32
Splitting into two groups
x^2y + 8y+ 4x^2 +32
Factor y out of the first group and 4 out of the second group
y( x^2+8) + 4(x^2+8)
Factor out (x^2+8)
(x^2+8) ( y+4)
Answer:
(x^2+4)(y+3)
Step-by-step explanation:
x^2y+4y+3x^2+12
factor by grouping
=x^2y+4y + 3x^2+12
left. right
take common in left y and in right 3
=y(x^2+4) + 3(x^2+4)
now common term is (x^2+4)
=(x^2+4) (y+3) answer
Answer:
the function for y=-4x+3
= soln,
y=mx+b"
40 pigs.
p=pigs c=chickens.
4p=pigs have 4 legs.
2c=chickens have 2 legs.
4p+2c=200
p+c=60
4p+2c=200
(-4)p+c=60
4p+2c=200
-4p-4c=-240
-2c=-40
c=20
p+20=60
p=60-20
p=40
Hope this helps!

x^2 + 3x = 10
Answer:
Step-by-step explanation:
We shall use middle term split method to find the factor
here middle term is 3 ,factor of -10 which gives -3 on adding
such numbers are -10 = 5 and -2
5+(-2) = 3
And then making two groups and simplifying it ,we get the roots
B=6a3 + 22a2 + 26a –10
C=18a3 + 10a2 + 14a – 10
D=28a3 + 14a – 10
Answer:
A is the answer
