This would be 5^2 because you have to subtract the exponents.
Answer:
Step-by-step explanation:
<u>In 4 seconds the rock will be at:</u>
- 2*4 = 8 in from the surface
<u>Add 5 feet to this to get the required distance:</u>
- 5 ft + 8 in = 5*12 in + 8 in = 68 in
The answer is C: Expression b and d
Expression A is used when you want to know how much $$ was taken off the original
Expression C won’t work at all because it’s like saying what is $1 subtract discount.
Expression B and D is saying original,P, subtract discount price=sales price
Answer:
Option C is correct
a + 0 = a
Step-by-step explanation:
Additive identity:
For any real number x,

We have to find an example of the additive identity from the given options.
Option A.
a+(-a) = 0
Which does not follow the additive identity.
Option B.
a+0 = 0
which does not follow the additive identity.
Option C.
a+0 = a
this equation follows the additive identity.
Therefore,an example of the additive identity is, a + 0 = a
