X/4 = 8
multiply both sides by 4 to get the value of x
x=32
0.05 then divide each number by 50% then simplify or if it’s a small number then just leave it
Answer:
The x intercept is (-2,0)
the y intercept is (0,4)
AK = 640
Δ ABC and ΔFJK are similar. They are small triangles.
ΔCDF is the big triangle.
640 / 2 = 320 m= CF
AC & FK= 320/2 = 160 m each
2AC = CF = 2FK
2(160) = 320 = 2(160)
BG = 20 m
20/160 = x / 320
20*320 = 160x
6400 = 160x
6400/160 = x
40 = x
Area of CDF = (40 m * 320 m)/2 = 12,800 / 2= 6,400 m²
<span>Just list all elements that belong both to A and to B
A ∩ B = {6,12}</span>
