-50
Step-by-step explanation:
it could be X-50=?
X=4 x=-4 Due to the difference in squares theorem
Answer:
Step-by-step explanation:
2 coins are 0.25 = 50 cents. That leaves 92-50 = 42 cents and 5 coins to go.
The only way to get 2 cents is to have 2 pennies. That leaves 40 cents and 3 coins to go.
The only way to get 40 cents with 3 coins is 1 quarter, 1 dime, and 1 nickel.
So you have 3 quarters = 75 cents.
2 pennies = 2 cents.
1 dime = 10 cents.
1 nickel = 5 cents.
92 cents total and 7 coins.The only way to get 40 cents
Answer:
0.012
Step-by-step explanation:
Linear approximation says that,
For a cube the surface area is .
So the side is 1.0 inch in, the surface area is square inches.
In Linear approximation means you ignore the term , if is a small number, because then will be a very smalle number and that does not contribute much to the error.
So the surface area is approximately,
So here,
The error in the area is approximately,
So the error is 0.012.
