Answer:
The middle two expressions shown are not polynomials
Step-by-step explanation:
Polynomial terms have positive integer exponents on any variables. A 2/3 power is not an integer exponent. Division by y is equivalent to an exponent of -1, which is not a positive integer.
And what else you can not solve that problem
Answer:
1269 square meters
Step-by-step explanation:
The path and the plot of land form two concentric circles (they have the same center). The radius of the plot of land is 100m (half of the diameter) and the radius of the larger circle, formed by putting a 2m wide path around the plot of land, is 102m. Thus, the area of the path is
minus
which will be
which is
. Estimate
to 3.141 and calculate, getting 1268.964... which is 1269, rounded to the nearest square meter.
Hope this helps :)
16 and -16 have an absolute value of 16
Answer:
35°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 given angles from 180° for missing angle
missing angle = 180° - (90 + 55)° = 180° - 145° = 35°
