Answer:
You put 8i^2 instead of 12i^2. You multiply -6i by -2i which equal -12i^2
Step-by-step explanation:
-7 + 6i - 14i+ 12i^2
-7 - 8i - 12
-19 - 8i
Answer:
x = -1
y = 4
Step-by-step explanation:
i believe this shape is a rhombus because the diagonals are perpendicular and bisectors, meaning m∡A = m∡B = m∡C = m∡D
so AC = CB = BC = DA
y + 1 = 2y - 3
1 = y - 3
4 = y
Plugging in 4 for 'y' means all sides are equal to 5
find x: 2x + 7 = 5
2x = -2
x = -1
