Answer:
45×7
Step-by-step explanation:
a) 2^13 / 2^18
b) 216
m = (y2-y1)/ (x2-x1)
m=(8-6)/(4-1)
m=2/3
4cm^2
First we need to find the length of the height of the triangle using Pythagoras:
a^2+b^2=c^2 (Substitute in what we have)
a^2+3√2(^2)=2√5(^2) = a^2 + 18 = 20 -> 20-18=2 √2=BD
Now we can find the area:
AD+DC= 3√2 + √2 = 4√2 x √2 = 8/2 = 4
