The expression given in the question can be simplified by getting them out of the brackets and then adding and subtracting the like terms. This will yeild the desired result.
<span>(-1+6i)+(-4+2i) = - 1 + 6i - 4 + 2i
= -5 + 8i
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the third option or option "c".</span>

Answer:
a) 1/4
b) 0.95
Step-by-step explanation:
0.25 is 25/100, which is 1/4
19/25 is 95/100, which is 0.95
Part A.
Using the Pythagorean theorem,
PR² = PQ² +QR²
PR² = (14 ft)² +(6 ft)² = 196 ft² +36 ft² . . . . substitute the given numbers
PR² = 232 ft² . . . . . . . . . . . . . . . . . . . . . . . .find the sum
PR = √(232 ft²) ≈ 15.23 ft . . . . . . . . . . . . . take the square root
The length of rod PR is 15.23 ft.
Part B.
Using the Pythagorean theorem,
PR² = PQ² +QR²
(16 ft)² = (14 ft)² +QR² . . . . . . . substitute the given numbers
256 ft² -196 ft² = QR² . . . . . .. subtract 14²
60 ft² = QR² . . . . . . . . . . . . . . find the sum
√(60 ft²) = QR ≈ 7.75 ft . . . . . take the square root
The new height QR is about 7.75 ft.
