The answer is D.

√-6(√-4 - √3) =
<span>
√-6 = </span>√-1√6 = i√6   Express <span>√-6 in terms of i
</span>i√6(√-4 - √3)

√-4 = √-1√4 = i √4 Express <span>√-4 in terms of i
</span>i√6(i√4 - √3)

√4 = 2 simplify radicals
i√6(2i - √3)

√6(2i - √3) = 2i√6 - 3√2  Distribute √6 over 2i-√3
i(2i√6 - 3√2)

i(2i√6 - 3√2) = -3i√2-2√6 Distribute i over (2i)√6 - 3√2
-3i√2 - 2√6

factor -1 from -3i√2 - 2√6

= -(2√6 + 3i√2)  == -2√6 - 3i√2

hope that helps!

First, simplify each one.

9.98 x 10^6 = 9980000

7.3 x 10^7 = 73000000

Next, subtract the freight from the aircraft

73000000 - 9980000 = 63020000

Round the decimal point to the first significant digit, and place the amount of place values the decimal point moved to the left as a power sign, over 10.

63020000 = 6.302 x 10^7

6.302 x 10^7 is your answer

hope this helps

I really need help on this !!
Naddik [55]

Answer:

r = -1

Step-by-step explanation:

(y2-y1)/(x2-x1)=m

(r,7)=(x1,y1) and (3,4)=(x2-y2) and m=-3/5

so plug in...

(4-7)/(4-r)=-3/5

then solve for r which will get that r = -1

numerator: 4-7=-3

denominator: 4-r=5 -> 4-5=0+r -> -1=r
