Answer:
it is 5.7
Step-by-step explanation:
4.25 × 1.40
5.95 - 0.25
5.7 or 5.70
I think the answer is -3.607
Last time I checked- it was a rhombus.
Answer:
One sqrt(7)*x -49sqrt(x)
Two -30sqrt(2)a
Right: - 3 cuberoot(2a)
Step-by-step explanation:
Left Questions
One
sqrt(7)x ((sqrt(x) - 7sqrt(7) ) Remove the Brackets
- sqrt(7x) * sqrt(x) - sqrt(7x) * 7sqrt(7)
- √(7*x)*sqrt(x) - 7*7*sqrt(x) Combine
- √7 (x) - 49x
This question has a a slight bit of ambiguity in it. Is the x outside the brackets underneath the root sign or not? I have taken it as not. Leave a note if I am wrong. <em><u>Edit</u></em>: This question clears itself when you use the original statement. I think it is correctly represented now. When you use √ you have to use brackets to show what is under the root sign.
Two
You can take a lot of common factors out side the brackets.
The common factors are 3*sqrt(2)*a When you do that, you are left with
- 3*sqrt(2)*a * ( 11 - 21)
- 3*sqrt(2)*a * (-10)
- The final answer is
- -30sqrt(2)*a
Of course there are other, more direct ways of doing this.
Right Question.
The problem here is answering in such a way that you are showing work.
Let z = 3∛(2a)
The problem now becomes
z*(1 - 2)
- z
Now substitute back
-3∛(2a) Answer
