Answer:
7.5m²
Step-by-step explanation:
A=½b×l
A=½×7.5×2
A=7.5m²
Answer:
d = 2* sqrt(a^2 + b^2)
Step-by-step explanation:
Interesting question. You should begin by noting that 0 is not the answer although it looks like it should be.
P = (a,b)
Q= (-a,-b)
x1 = a
x2 = - a
y1 = b
y2 = - b
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
d = sqrt( (-a - a)^2 + (-b - b)^2 )
d = sqrt ( -2a)^2 + - (2b)^2 )
d = sqrt(4a^2 + 4b^3)
d = 2* sqrt(a^2 + b^2)
I believe the area of the blank rectangle, the biggest one, is 2800. The whole rectangle all together is 3225.
Explanation:
Since the length of one of the rectangles is 70, the rectangle with an area of 210 will have a side length of 3. This means the rectangle with an area of 15 has a side length of 5. <em>That</em> means the rectangle with an area of 200 has a side length of 40. Therefore, the blank rectangle has an area of 2800, as it's 2 side lengths are 70 and 40.
Answer:
3x² - 2x - 6
Explanation:
We are given that:
f (x) = 3x² - 2
g (x) = 2x + 4
We want to find the value of (f - g)(x), this means that we will simply subtract g (x) from f (x) as follows:
(f - g)(x) = f (x) - g (x)
(f - g)(x) = 3x² - 2 - (2x + 4)
(f - g)(x) = 3x² - 2 - 2x - 4
(f - g)(x) = 3x² - 2x - 6
Hope this helps :)
It would be communitive property
