378 cm is the volume hope this helped
Step-by-step explanation:
perimeter of square = 30cm
perimeter of rectangle = 30cm
area of square is = 30×30= 900 cm
hope it helps , make sure to follow !!!!
Answer:
x = 7/3
Step-by-step explanation:
Factors of 9 are:
3x3
9x1
Factors of 49 are:
7x7
49x1
Only 3x3 and 7x7 equal 42 when you expand it out (3x - 7)(3x - 7) = 0
x = 7/3
Find your common denominator
which is 4y so multiply 4y to both fractions which means top and bottom
your final answer is
36 -y
------
4y
The explanation for this is one of my favorite pieces of mathematical reasoning. First, let's thing about distance; what's the shortest distance between two points? <em>A straight line</em>. If we just drew a straight line between A and B, though, we'd be missing a crucial element of the original problem: we also need to pass through a point on the line (the "river"). Here's where the mathemagic comes in.
If we take the point B and <em>reflect it over the line</em>, creating the point B' (see picture 1), we can draw a line straight from A to B' that passes through a point on the line. Notice the symmetry here; the distance from the intersection point to B' is<em> the same as its distance to B</em>. So, if we reflect that segment back up, we'll have a path to B, and because it came from of the line segment AB', we know that it's <em>the shortest possible distance that includes a point on the line</em>.
If we apply this same process to our picture, we see that the line segment AB' crosses the line
at the point (1, 1)
