marissa [1.9K]

The scale factor for area is the square of the scale factor for linear dimensions. If linear dimensions are scaled up by a factor of 10, the area is scaled up by a factor of 10² = 100.

The area of the larger box is 100×432 cm² = 43,200 cm².

The first three steps for solving the quadratic equation by completing the square are shown. Fill in the missing number in the l
gulaghasi [49]
Completing the square is done as follows:

1. Write the equation in a way that the constants are in the right side while the terms with x are on the left. 
<span>9x2 +54x = 7
</span>
2. Make sure that the coefficient of the x^2 term is 1.
<span>9(x2 + 6x) = 7
</span>
3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
<span>9(x2 + 6x + 9) = 7 + 81

9(x+3)^2 = 88
</span>

tino4ka555 [31]

ANSWER

3{a}^{4 }

EXPLANATION

The cube root of

27 {a}^{12}

is

\sqrt[3]{27 {a}^{12} }

This is the same as:

(27 {a}^{12} )^{ \frac{1}{3} }

( {3}^{3} ({a}^{4})^{3}  )^{ \frac{1}{3} }

=  (3{a}^{4} )^{3 \times  \frac{1}{3} }

= 3{a}^{4 }

Ok so let me help you with this. Here is the procedure:
 <span>r² = x² + y² = 8² + 6² = 100 
r = 10 
x = r cosθ 
y = r sinθ 
sinθ = y/r = 6/10 = 3/5
