Answer:
4x^4+3x^2y^2+9y^2
(2x^2)^2 + 2×2x^2×3y^2 + (3y^2)^2 - 9
(2x^2 + 3y^2)^2 - (3)^2
(2x^2 +3y^2+3)(2x^2+3y^3-3)
Answer:
42.5
Step-by-step explanation:
110 - 25 divided by 2 because
angle ABC = (angle AC- angle DE)÷2
to get the slope of a line, we only need two points, notice, the grid is using 2 numbers per line, so the point on the bottom-left is (-6,0) and the one on the upper-right is (6,4), so let's use those points.
