Answer:

6.12 × 10^5.

Step-by-step explanation:

3.4 × 10² × 1.8 × 10³

To solve this, we can group.

$(3.4 * 1.8) * (10^2 * 10^3) =$ $(6.12) *(10^5).$

Therefore, $(3.4 *1.8)*(10^2*10^3) = 6.12 * 10^5$

Stacey's text messaging plan charges 20¢ for each message over 450 in addition to a $14 base charge. If she owes $18.00 for text

Sidana [21]

$18 = 14 + 0.20(t)

- 14

4 = 0.20t

Divide 4 by 0.20

t = 20

0.20 * 20 = 4

4 + 14 = 18

Because it only charged her for texts after 450, its 450 + 20.

470. She sent 470 texts that month.

Simplify (-7+3i)^2+(-2+8i)<br> Show all work

Gnoma [55]

Answer:

$(-7 + 3i)^{2} + (-2 + 8i) = 38 - 36i$

Step-by-step explanation:

(-7 + 3i)(-7 + 3i) + (-2 + 8i)

$49 - 21i -21i + 9i^{2} = 49 - 42i -9 = 40 - 42i$

40 - 42i + (-2 + 8i)

38 - 36i
