Answer:

9

18

Step-by-step explanation:

<u>x = 2:</u>

4(4 + 2 - 3) - 6 + 3 = 12 - 6 + 3 = 9

<u>x = 3:</u>

4(6 + 3 - 3) - 9 + 3 = 24 - 9 + 3 = 18

Answer:

9x -9

9(x - 1)

4(3x-3) - 3x + 3

Step-by-step explanation:

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

Combine like terms

4(3x-3) - 3x + 3

Distribute

12x -12 -3x+3

Combine like terms

9x -9

Factor out 9

9(x-1)

How can I solve for the logarithm?
Sergio039 [100]
\bf 12^{2x-8}=15\\\\&#10;-----------------------------\\\\&#10;log_{{  a}}\left( x^{{  b}} \right)\implies {{  b}}\cdot  log_{{  a}}(x)\impliedby thus\\\\&#10;-----------------------------\\\\&#10;log\left( 12^{2x-8} \right)=log(15)\implies (2x-8)log(12)=log(15)&#10;\\\\\\&#10;2x-8=\cfrac{log(15)}{log(12)}\implies 2x=\cfrac{log(15)}{log(12)}+8\implies &#10;x=\cfrac{\frac{log(15)}{log(12)}+8}{2}

Find the area of this shape. Correct answer will Brainliest
Iteru [2.4K]

Answer:

As shown in picture, this is a trapezoid.

The area of a trapezoid is calculated by:

A = (base1 + base2) x height x (1/2)

To work out A, we need to find out base1, base2, and height.

base1  = YZ = \sqrt{(Zx - Yx)^{2} + (Zy - Yy)^{2} } = \sqrt{(5 - 2)^{2} + (5 - 5)^{2} } = 3

base2 = XW =\sqrt{(Wx - Xx)^{2} + (Wy - Xy)^{2} } = \sqrt{(8 - 1)^{2} + (1 - 1)^{2} } = 7

Otherwise, the height (distance between base1 and base2) is 4 as shown in picture.

=> A = (3 + 7) x 4 x (1/2) = 20

Hope this helps!
