Answer:
1) 2a+4a+10-6= 6a + 4
2) 3x-5x+7-7= -2x
3) - 15b+10 +10b= -5b + 10
4) - 4d+d-8-6+3b= - 3d - 14 +3b
The pattern is going up by elevens each time. So basically you take the second number(A2) and subtract it from the first number(A1).
so short answer is: 46, 57, 68
Answer:

Step-by-step explanation:
Convert m to cm,
0.045m =4.5cm
0.034m = 3.5cm
0.01m = 1cm
Volume = 4.5 cm × 3.5 × 1 = 15.75 cm3
The rule is 3^x.
Check: 3^1 = 3; 3^2 = 9; 3^3 = 27 and 3^4 = 81
