The question asks for the square root of 3*3*5*5
√3*3*5*5
lets multiply the numbers together first
√9*25
√225
now use your calculator and solve for the square root
√225=15
Answer=15
Answer:
3x - 6 = x + 9
2x - 6 = 9
2x = 15
x = 7.5
Step-by-step explanation:
"A parabola is curved instead of linear, in your case it is probably just facing up or down so I won't get into square roots for now.So the quadratic equation that you probably have had to memorize (or will soon) is:
x=(-b[+or-]√(b²-4ac))/2a when you have an equation like ax²+bx+c=0Now where does the curve shape come from? You see that little pesky plus or minus in the equation? That's because there are always 2 values (inputs) that will generate the same output. Example:y=x²(2)²=4(-2)²=...4So if you were to follow this pattern, and plot the points on a graph, you would end up with a curve. You end up with a curve because the slope is constantly increasing.
And this is actually where you start the study of Calculus(!), which is all about measuring slopes (And a bunch of other stuff, but this is the easiest part to explain). Actually, in this case of y=x², the slope at any given point (funnily enough) is equal to 2 times your x-value.
The point is, your line is curved because unlike a linear equation, the slope is changing (at a constant rate)."
The value of w is 5 units
Step-by-step explanation:
Let l be the length of the rectangle
and w be the width
Then
l = 2w - 1
Dividing both sides by 6
Hence
The value of w is 5 units
