Answer:
4. Ethan is correct because the absolute value bars are grouping symbols so first you must subtract. 7 minus 3 = 4, and StartAbsoluteValue 4 EndAbsoluteValue = 4
Step-by-step explanation:
Claim :
|7 - 3| = 4
The absolute sign or meaning means dropping the negative sign pertaining to a certain calculation, by doing this, if the result of the question or expression is negative, the negative sign is dropped and the number is being treated as positive.
Therefore,, the expression ; |7 - 3| = 4 is corect.
Answer:
The area after 13 years will be 1141 km2
Step-by-step explanation:
This problem can be modeled with an exponencial equation:
A = Ao * (1+r)^t
Where A is the Area after t years, Ao is the inicial area and r is the rate that the area changes.
For our problem, we have that Ao = 2300, r = -5,25% = -0.0525 and t = 13.
Then, we can find the area after 13 years:
A = 2300 * (1 - 0.0525)^13
A = 2300 * (0.9475)^13 = 1140.93 km2
Rounding to the nearest square kilometer, we have A = 1141 km2
Triangles are congruent when they can be changed by a series of transformations
6 + 7 = 13 - 7 = 6 or 13 - 6 = 7
