54^2=54x54
=(50+4)(50+4)
=50^2 + 2x50x4 + 4^2
=2500 + 400 + 16
=2916

Explanation below, but in short, a fraction means to divide the top/left number by the bottom/right number. It means to divide 5 by 6.
5/6 = 0.83333333...
Why is this? This is because a fraction simply means to divide the numerator (the top/left number) by the denominator (bottom/right number). So 5 ÷ 6 = 0.83333333... in decimal form.
the answer is 228 I was wrong when I said
I think the choices is wrong
So I went ahead and divided up the figure so that you would understand what I'm going to tell you. Let's start with the red rectangle.
The distance from point R to point I is 6 units and the distance from Point R to point S is 5 units. 6*5 = 30 so that red rectangle has an area of 30 units
Now let's calculate triangle AVI. Area of a triangle is Base * Height. The base is 1 and the height is 5 which means the area of triangle AVI is 5.
Next, triangle ALT. From Point A to point L is 4 unit. From Point L to point T is 3 units. 4*3 is 12. So triangle ALT has an area of 12.
Triangle TSI. From Point T to point L is 3 units. From Point L to X is 2. Triangle TSI has an area of 6.
Now we add all of them up. 30+5+12+6 = 53. In total, RSTUV has an area of 53
16-3y because you distribute through the parenthesis frist and then you solve for your answer
