Calculate the area of the square shown below (HARD)
sergey [27]
Check the picture below.

recall that in a square, all sides are equal, so if we make b = a, then we get that for one side, also recall that the area of a rectangle is length*width, so in this case,

\bf \stackrel{\textit{area of the square}}{\stackrel{length}{5\sqrt{2}}\cdot \stackrel{width}{5\sqrt{2}}}\implies 25(\sqrt{2})^2\implies 25\cdot 2\implies 50

6. A line that passes through the point (–1, 3) has a slope of 2. Find another point on the line. A. (0, 5) B. (–3, 2) C. (1, 4)
Bezzdna [24]
The answer is A because if we stare with (-1,3) and go up by 1x, since the slope is 2, then 3 + 2 is 5 and we have (0,5). Hope this helps!

I really need help asap please

We can use the substitution method to solve this problem.

The second equation is \sf y=2x, so we can plug in 2x for 'y' in the first equation:

\sf 5x-2y=3

\sf 5x-2(2x)=3

Multiply:

\sf 5x-4x=3

Combine like terms:

\sf x=3

This is the x-value of our solution, we can plug this into any of the two equations to find the y-value:

\sf y=2x

\sf y=2(3)

Multiply:

\sf y=6

This is the y-value of our solution. So our entire solution is (3, 6).

40y^3 + -8y^2 + 2y^3

Combine terms: 40y^3 + -8y^2 + 2y^3
(40y^3 + 2y^3) + (-8y^2)
