Answer: ∠BDA = 21; CB = 30

have:

sin ∠BDC = \frac{4x+6}{BD}

sin ∠ADB = \frac{7x-12}{BD}

because ∠BDC = ∠ADB => sin ∠BDC = sin ∠ADB

=> \frac{4x+6}{BD}=\frac{7x-12}{BD}

=> 4x + 6 = 7x -12

<=> 3x = 18

<=> x = 6 => CB = 4.6 + 6 = 30

Need answer ASAP!!<br> Find the area of the shaded region.
qwelly [4]

Answer:

(5x² +7x -26) units²

Step-by-step explanation:

\boxed{area \: of \: rectangle = length \times breadth}

Area of shaded region

= Area of larger rectangle -area of smaller rectangle

Area of larger rectangle

= (3x -4)(2x +2)

= 3x(2x) +3x(2) -4(2x) -4(2) <em>(</em><em>Expand</em><em>)</em>

= 6x² +6x -8x -8

= 6x² -2x -8

Area of smaller rectangle

= (x -6)(x -3)

= x² -3x -6x +18 <em>(</em><em>Expand</em><em>)</em>

= x² -9x +18

Area of shaded region

= 6x² -2x -8 -(x² -9x +18)

= 6x² -2x -8 -x² +9x -18

= 5x² +7x -26

6 times 7 to the second power
Travka [436]
Hello!

To solve this question, we must first add the exponent into the number 7 before multiplying it by the number 6. 

7 to the second power simply means 7x7. 

7x7= 49

Now that the exponent is in the equation, we can multiply 49 by 6 to find your final answer. 

6 x 49 = 294

I hope this helps answer your question! Have a great day!
