Follow PEMDAS. First is multiplication.
Follow the FOIL method: (First, Outside, Inside, Last)
<span>(8 - 3i) - (8 - 3i)(8 + 8i)
</span>8(8) = 64
8(8i) = 64i
-3i(8) = -24i
-3i(8i) = 24 (note: two "i"'s = -1)
Combine like terms
64 + 64i - 24i + 24
64 + 40i + 24
88 + 40i
Now subtract 88 + 40i from 8 - 3i
(8 - 3i) - (88 + 40i) = -80 - 43i (Note: the signs in the parenthesis change, because you are subtracting as a whole)
-80 - 43i is your answer
hope this helps
Answer:
The gradient is 1
Step-by-step explanation:
m, gradient= (y2-y1) ÷ (x2-x1)

Step-by-step explanation:
3 ÷ 3/4 or 0.75 = 4
Answer:
QP = 5
Step-by-step explanation:
since QRST is a rectangle, and QRST intersect at P, then QTS and QRS are right triangles.
because <T is a right angle, line TR passes through the midpoint of line QS, therefore 2(QP) = QS
10/2 = 5
