Multiply and simplify: sq rt 7x ((sq rt x)-7sq rt. 7)

jarptica [38.1K]

7x(√x - 7√7) Multiply √7x to "√x" and "-7√7" respectively:
√7x*√x - 7√7*√7x
First is to simplify: √7x² - 7√7²x
Extract the squares: x√7 - 7*7√x

Then, we simplify: x√7 - 49√x
After simplifying the equation, I got the answer x√7 - 49√x.

-2.2 + 0.3z= 3 -0.5z -0.8z<br> what does z equal

wariber [46]

$-2.2 + 0.3z= 3 -0.5z -0.8z \\ \\ 0.3z - 2.2 = 3 - 0.5z - 0.8z \\ \\ 0.3z - 2.2 = 3 - 1.3z \\ \\ 0.3z = 3 - 1.3z + 2.2 \\ \\ 0.3z = -1.3z + 5.2 \\ \\ 0.3z + 1.3z = 5.2 \\ \\ 1.6z = 5.2 \\ \\ z = 3.25 \\ \\$

The final result is: z = 3.25.

Form a sequence that has two arithmetic means between -1 and 59.

9966 [12]

Answer:

Correct choice is B

Step-by-step explanation:

For the numbers -1 and 59, find the difference 59-(-1):

since 59-(-1)=60 and $\dfrac{60}{3}=20$ (two arithmetic means tells you there will be three intervals), two arithmetic means will be
