$\frac{ 3\sqrt{3} }{2} \times a {}^{2} \\ \\ \frac{ \sqrt{27} }{2} \times 7 {}^{2} \\ \\ \frac{ \sqrt{27} }{2} \times 49 \\ \\ = 127.31cm {}^{2}$

<h3>So Option D=127.3cm²</h3>

Simplify the expression 5+6i/4+6i<br> A) 56-6i/-20<br> B) -16-6i/-20<br> C)56-6i/52<br> D) -16-6i/52

IRISSAK [1]

Answer:

$The\ simplified\ form\ of\ the\ \frac{5 + 6i}{4 + 6i}\ is\ \frac{56-6i}{52}.$

Option (C) is correct .

Step-by-step explanation:

As the expression given in the question as follows.

$= \frac{5 + 6i}{4 + 6i}$

Now rationalize the expression.

$= \frac{5 + 6i\times 4 - 6i}{4 + 6i\times 4 - 6i}$

Using the formula

a² - b² = (a - b) (a + b)

Using in the above

$= \frac{5 + 6i\times 4 - 6i}{(4)^{2} - (6i)^{2}}$

$= \frac{5\times 4-5\times 6i+6i\times 4-36\ i^{2}}{16 - 36(i)^{2}}$

As i² = -1

$= \frac{20-30i+24i+36}{16 + 36}$

$= \frac{56-6i}{52}$

$Therefore\ the\ simplified\ form\ of\ the\ \frac{5 + 6i}{4 + 6i}\ is\ \frac{56-6i}{52}.$

Option (C) is correct .

KatRina [158]

Answer:

Step-by-step explanation:

Work backwards:

6 is 3/5 of a number, and that number is 10
10 is 1/3 of a number, and that number is 30

Check your work:

2/3 of 30=20 toy to Sarah
30-20=10 toys left
2/5 of 10=4 toys to Ryan
10-4=6 toys left

If angle 1 and angle 2 are supplementary angles, and angle 3 and angle 2 are supplementary angles, what do you know about angle

dusya [7]

Answer:

angle 1 and angle 3 are congruent

Step-by-step explanation:

Angles supplementary to the same angle are congruent. Here both angles 1 and 3 are supplementary to angle 2, so angles 1 and 3 are congruent.

_____

If you like, you can get there algebraically:

m∠1 + m∠2 = 180

m∠3 + m∠2 = 180

Subtract the second equation from the first:

(m∠1 + m∠2) - (m∠3 + m∠2) = (180) - (180)

m∠1 -m∠3 = 0 . . . . simplify

m∠1 = m∠3 . . . . . . add m∠3

When angle measures are the same, the angles are congruent.

∠1 ≅ ∠3
