Answer:

3x - 3

Step-by-step explanation:

Hello!

The first thing you want to do is REMOVE the parentheses, because they are not needed. The equations in them have already been FULLY SIMPLIFIED.

But, DON'T throw those parentheses away! Our next step is to RE-ARRANGE our terms. Have the 'x terms' on one side, and the constants on the other, putting those parentheses around the two. Your equation should look like:

(x + 2x) + (4 - 7)

Our final step is to simplify.

(1)x + 2x = 3x

4 - 7 = -3

Therefore, your final answer is 3x - 3

Hope this helped!

Answer:

3x - 3

Step-by-step explanation:

(x + 4) + (2x - 7) =

The first step is to drop the parentheses since they are unnecessary.

= x + 4 + 2x - 7

Now group like terms together.

= x + 2x + 4 - 7

Combine like terms.

= 3x - 3

Difference of squares:

y^4−25

16x^2−81

Not difference of squares:

20m^2n^2−121

p^8−q^5

Step-by-step explanation:

y^4−25

(y²)² - 5²

16x^2−81

(4x)² - 9²

20m^2n^2−121

20 is not a perfect square

p^8−q^5

q⁵ is not a perfect square

The graph of g(x) is obtained by reflecting the graph of f(x)=2|x| over the x-axis.

Lera25 [3.4K]

Answer: Choice C)
g(x) = -|2x|

You get this answer by simply sticking a negative out front of the original function. In other words, g(x) = -f(x) or more technically, g(x) = -1*f(x).

The negative will flip every y coordinate from positive to negative (or vice versa)

You'll also use the idea that |2x| = 2|x|. The two can be pulled out since we can say |x*y| = |x|*|y|
So |2*x| = |2|*|x| = 2|x|

Answer:

Only the isosceles trapezoid has an area of 32 cm².

Step-by-step explanation:

Let's calculate the area of each polygon.

For the two triangles we have:

$A_{t} = \frac{bh}{2} = \frac{2 cm*4 cm}{2} = 4 cm^{2}$
