The two numbers are 41 & 37.
The way to solve this is by setting up an equation. We know that 2 numbers are going to equal 78, so here would be the general equation (let x represent the number we don't know):
(x) + (x + 4) = 78
Now, we need to simplify it (combine like terms):
2x + 4 = 78
Then you can solve it like any other equation. Subtract 4 on both sides:
2x = 74
Divide by 2 on both sides:
x = 37.
So, now you know one number is equal to 37 and that the other is 37 + 4.
That's how you get 37 & 41.
Rain and snow are continually forming within clouds and falling back to the surface, completing one element of the Earth's hydrologic cycle. The latent heat of condensation, absorbed when the water evaporated, is released to the atmosphere when the water vapor condenses back into cloud water
Answer:
The Answer is 31.5
Step-by-step explanation:
Given:
depreciation rate: 18%
Value of the car : 20,000
Age of the car : 4 years.
The depreciation is based on the current value of the car. Therefore, the amount of depreciation varies.

The current value of a car bought 4 years ago is 9,042.44
Beginning value : purchased amount on 1st year. then, ending balance of the previous year from 2nd year onwards.
Depreciation : Beginning value * depreciation rate
Ending value : Beginning value - depreciation
It’s wrong because it isn’t one of the zeroes for the equation
f(x)=-16x^2+64x+80
Divide by -16
x^2-4x-5
(x-5)(x+1)
Set them up to zero
x-5=0. x+1=0
x=5. x=-1
5 and -1 are your possible zeroes
