Answer:
7x³y² - 3x²y² + xy - 5
Step-by-step explanation:
Add like terms.
5x³y² + 2x³y² = 7x³y²
-3x²y² = -3x²y²
-3xy + 4xy = xy
2 - 7 = -5
Put them all together.
7x³y² - 3x²y² + xy - 5
Answer:
a triangle;
Three faces of the cube meet to form the vertex, so the cross section is a two-dimensional figure with three sides
Step-by-step explanation:
Step-by-step explanation:
False.
intersects the y-axis => x=0
tan (0+ π/6) = tan π/6 = 0.58
instead of 1.73
5x10+3÷4x5+8-45x6x23÷4= 1,009.125
