Answer:

-12 - 10i

Step-by-step explanation:

We are subtracting 3 + 2i from -9 - 8i.  Rewrite the left side as -3 - 2i and then ADD this result to -9 - 8i:

-9 - 8i

Answer:

-9-8i)-(3+2i)

= -9-8i-3-2i

Separate i and the numbers

= (-9-3)+(-8i-2i)

= -12-10i

A bee flies 25 m north of the hive then 10 m east 5 m west and 10 m south. How far north and east of the hive is it now? Explain
mafiozo [28]

Answer:

20 meters north.

Step-by-step explanation:

(I did it on a paper not to lose track.) First we go 25 north. Then ten east. Five south. And 10 west again. So in East/West we didn't move but we moved 5 down/south so we are still at twenty. If you don't understand still draw it on a paper.

Determine whether the two expressions are equivalent. If so, tell what property is applied. If not, explain why. 7 · (6 · t) and
Georgia [21]
The two expressions are equivalent because the associative property of multiplication is applied, which means that no matter where you put the parenthesis, the two expressions will still be equal.

PLZ HELP IN A RUSH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Bumek [7]

Answer:

Her new balance = - 92.34

Step-by-step explanation:

First find out what the check did.

She had $63.44 in her account. Her check caused her to be in the whole

63.44 - 186.56 = -123.12

Now she deposited 1/4 of that amount.

- 123.12 + (1/4)(123.12) = - 123.12 + 30.78

Her new balance = - 92.34

The hypotenuse of a right triangle measures 18 cm and one of its legs measures 12 cm. Find the measure of the other leg. If nece
Serggg [28]

Answer:

16 cm

Step-by-step explanation:

A right triangle, with the hypotenuse = 18, one side = 7, and the other side = x.

Since this is a right triangle, use the pythagorean theorem to find the value for x.

let a = 7 for one side, and let c = 18 for the hypotenuse. And, let c = x for the other side.

The pythagorean theorem is: c^2 = a^2 + b^2.

18^2 = 7^2 + x^2324 = 49 +x^2

x^2 = 324 - 49 = 275So, x = sqrt(275) = 16.5 cm
