Hey there :)

9( n - 4 ) - 4n ( n - 4 )
We can take ( n - 4 ) as common as both are getting multiplied by ( n - 4 )

We can join 9 - 4n together

Therefore, the final answer will be ( n - 4 )( 9 - 4n )

9(n-4) - 4n(n-4)

Here you see that there are two (n-4). So you have to factor (n-4).

It gives : (n - 4) (9 - 4n).

In short, the answer would be the option A.

Hope this helps !

Solve: -1/4 (2x + 8) = -6​
vredina [299]

Answer:

x = 8

Step-by-step explanation:

-1/4 (2x + 8) = -6​

Multiply both sides by -4.

2x + 8 = 24

Subtract 8 from both sides.

2x = 16

Divide both sides by 2.

x = 8

Deondra is 1.35 meters tall. At 10 a.m., she measures the length of a tree's shadow to
pashok25 [27]

Answer:

If the length of a tree's shadow is 35.25 meters. The height of the tree to the nearest hundredth of a meter will be : 11.74m

Given:

Denora height=1.35 meters

Length =35.25 meters

Width =31.2 meters

Height of the tree=x

Proportion:

1.35 : 35.25 :: x : 31.2

Now let's determine the height of the tree:

35.25 - 31.2 / 1.35 = 35.25 / x

4.05 / 1.35 = 35.25 / x

Cross multiply

4.05x = 35.25 × 1.35

4.05x = 47.58

Divide both sides

x = 47.58 / 4.05

<u>x = 11.74</u>

In conclusion, if the length of a tree's shadow is 35.25 meters. The height of the tree to the nearest hundredth of a meter will be: 11.74m

Please help with my math i am stuck please explain

For the addition problem 1/4 would turn into 2/8 and the 3/8 would stay the same therefore it would be 2/8 + 3/8 =5/8. Then for the subtraction problem 1/4 would turn into 2/8 and 3/8 would stay the same therefore it would be 2/8 - 3/8 =1/8
