Answer:
By adding 4 to both sides.
2= -4 +b
2= b -4
2+4= b-4 +4
6= b
Another way to look at it is to move all the constants to one side. Here we have the constant 2 on the left hand side, and on the right we have the constant -4 and the variable b.
To isolate b, we move the constant -4 to the left hand side. Moving a number to the other side of the equal sign changes the sign of the number. So, -4 becomes a +4 on the left hand side.
2 +4= b
6= b
You can take out 2x^3 from both terms making it
2x^3 (15+8x^2)
Answer is B
18 = 2 x 3 x 3
8 = 2 x 2 x 2
Lowect common denominator is 2 x 2 x 2 x 3 x 3 = 72
Answer:
Standard Form To change a number from scientific notation to standard form, move the decimal point to the left, or to the right. You should move the point as many times as the exponent indicates. Do not write the power of ten anymore. hope I helped

Answer:
Step-by-step explanation:
2/3 + 2/5 = 10/15 + 6/15 = 16/15 tins per day
24 tins divided by 16/15 = 24/1 divided by 16/15
To divide one fraction by another, take reciprocal of the other and then multiply.
24/1 x 15/16 = 360/16 = 22 1/2 days
