Answer:
CD = 27
Step-by-step explanation:
Given the triangles are similar then the ratios of corresponding sided are equal, that is
= , substitute values
= = 3 ( multiply both sides by 9 )
CD = 27
Hello :),
2x+2=6
2x=6-2=4
x=4/2=2
So when x=2, 2x+2=6
==========================================================
When x=1
2×1+2=4
When x=3
2 × 3 +2 =6+2=8
When x=4
2 × 4 +2 = 8+2=10
==========================================================
Substitute the valus of x and see which answer fits.
for x=0, y = 4·0 - 3 = -3
for x=1, y = 4·1 -3 = 1
Only the 2nd choice matches:
Input x 0 1 2 Output y -3 1 5
well taking into consideration the natural mixing of water, you should get 0.5x the concentration of salt
