Answer:
Step-by-step explanation:
For an expression to be a difference of squares, it must be a difference of two terms, each of which is a square. A term is a square if its coefficient is a square and if its degree is even.
The third expression is a sum, not a difference; the fourth expression has a term that is not a square (40). Neither of those is a difference of squares.
See the attached figure
t<span>he angle of the last turn was angle alfa in the point C
tan(alfa)=3/3.5=0.8571
alfa=arctan(0.8581)=40.60</span>°
<span>Round to the nearest degree---------> alfa=41</span>°
the answer is 41°
1 is 4 and 4 and 4 is 11 and 5 is 15
Answer:
We are given that the total volume of the sandbox is 330 cubic feet.
We are given the side measurements of 3 feet tall and 10 feet wide.
3 x 10 = 30 sq2
V(volume)= 330 ft3
330 ft3 divided by 30 sq2 = 11ft
In conclusion, the length of the box would be:
= 11 ft
