Combine like terms
assuming those 2s are exponents
-3x^2+2y^2+5xy-2y+5x^2-3y^2
move all x's together all y's together and all xy's together
-3x^2+5x^2+2y^2-3y^2+5xy
combne like terms
2x^2-y^2+5xy

1 term is negative
It is the first graph. Type into Desmos and it shows the graph for this eqution.
Answer:
-15
Step-by-step explanation:
-3 + -12 = -15
Because the problem represents right angle we can use simple geometric functions to determine size of sides of triangle and its angles if needed.
Since we have angle at point that is 42 feets away from base of the building and we need lenght of side that is oposite from that angle that means that we need some trigonometric function that includes those 2 sides.
that function is tangens.
tan67 = oposite side/side next to angle
tan67 = x/42
x = 42*tan67
x = 98.94 feet
Answer is D 99 feet
It would be 45.83 because the 3 (in the hundredths place) would stay the same as opposed to rounding up to four.
