Answer:
x = ±5sqrt(2)
Step-by-step explanation:
x^2 = 50
Take the square root of each side
sqrt(x^2) = ±sqrt(50)
x = ±sqrt(25*2)
We know that sqrt(ab) = sqrt(a) sqrt(b)
x = ±sqrt(25)*sqrt(2)
x = ±5sqrt(2)
Answer:
15n + 6
Step-by-step explanation:
We need to do this by "breaking it down" into smaller pieces.
"Six more than the product of 15
and a number"
The product of 15 and a number means <em>multiply the number (n) and 15, so we can write: 15*n </em>
<em>or simply, 15n</em>
<em />
Then we have six more than the ....
<em>This means we add six to the product just found, so 15n + 6</em>
<em />
<em>15n + 6 -- this is the expression</em>
Answer:
Option C is correct
unit and unit
Step-by-step explanation:
Area of a rectangle is given by:
....[1]
where
A is the area of rectangle
l is the length of a rectangle
w is the width of a rectangle.
As per the statement:
A certain rectangle has an area of
⇒
Now factor this trinomial :
⇒
⇒ unit square
On comparing with [1] we have;
unit and unit
Therefore,the length and width of the rectangle are:
unit and unit
