How do I simplify 3(2a-8b)

2 answers:

6 0

Well All you have to do is Just divide the 8 by the 4 and you get 2a-2b
Unless it's all over 4, if it is, you should have written it as (2a-8b)/4. The parentheses make a difference. ^ ^
If it is all over 4 you can rewrite it as (2a/4)-(8b/4) 
(2/4)a-(8/4)b 
(1/2)a-2b or (a/2)-2b 

Hope I helped :D

You would have to do distribution. So you would have to multiply 3 by 2a and multiply 3 by -8b. 3 times 2a equals 6a (always keep the letter) and 3 times -8b equals -24b. (if there is only one negative number when multiplying, always keep the negative sign.) now you are left with 6a-24b. and since we cant put a into b, your answer would be 6a-24b. hopefully this helped you and sorry if it confused you

In a genetic experiment involving flower color in phlox, a ratio of 3 blue-flowered plants to 1 whiteflowered plant was expected

aliya0001 [1]

Answer: The observed ratio is different from the expected ratio.

Step-by-step explanation:

Since we have given that

Expected ratio :

Ratio of blue flowered plants to white flowered plant = 3:1

Observed results:

Number of blue flowered plants = 35

Number of white flowered plants = 14

So, Ratio of blue flowered plants : white flowered plants

$35:14\\\\=5:2$

So, 5:2 ≠ 3:1

Hence, the observed ratio is different from the expected ratio.

Answer:

x = 18√3

Step-by-step explanation:

From the picture attached,

In a right triangle,

Measure of one angle = 30°

Measure of adjacent side of the angle = 9 units

We have to find the measure of Hypotenuse from the given properties.

By cosine rule,

cos(30°) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

$\frac{\sqrt{3}}{2} =\frac{9}{x}$

$x=18\sqrt{3}$

Therefore, measure of Hypotenuse is 18√3 units.
