Which statement describes how to solve ^3 squareroot x^2-6= ^3 square root 2x+2
Answers
Answer:
Square both sides and then solves the resulting quadratic equations
Step-by-step explanation:
The equation is 3sqrt(x^2-6)=3sqrt(2x+2)
We can solve this by;
First square both sides;
(3√(x²-6))²= (3√(2x+2))²
We obtain;
9(x²-6)=9(2x+2)
We simplify to obtain a quadratic equation;
x²-6=2x+2
= x²-2x-8=0
Then we solve the quadratic equation;
x²-4x+2x-8=0
x(x-4)+2(x-8)=0
(x+2)(x-8)=0
Values of x = -2 or 8
Answer:
Cube both sides and then solve the resulting quadratic equation.

first multiply 3.2*2.8 which equals 8.96 then multiply that number times 6.1 so like this-> 8.96*6.1 which your answer is 54.656.
So answers for numbers 1-3 are
1) 54.656
2) 90
3) 15.603

The best thing to do is to find ten percent.
To do this, divide both sides by 3, and this gives you
2m=10% (2m being 2 miles)
Therefore, to find 100%, you've got multiply both sides by 10
20m=100%

Answer:
7/50 meter.
Step-by-step explanation:
He has 7/8 meter. 1/5 of the piece of string is
.
Then, he uses 7/40 meter to tie a package. The rest of string will be
.
Then, the rest of string after he uses 1/5 is 7/10. Finally, he cuts the rest into 5 equal pieces, that is
.
Then, the lenght of each piece is 7/50 meter.
1/5 × 7/8 = 7/40
Now we have to subtract this from the original amount...
7/8 - 7/40 =
35/40 - 7/40 =
28/40 = 14/20 = 7/10
Now we divide this remaining string by 5 to find the length of the individual pieces...
7/10 ÷ 5 =
7/10 × 1/5 =
7/50 meter
