F(x) = 2x^2 + 5x
f(3b) = 2(3b)^2 + 5(3b) = 2(9b^2) + 15b = 18b^2 + 15b
Answer:
Additive Identity Property: The sum of any number and zero is the original number. For example 5 + 0 = 5
Step-by-step explanation:
Additive Identity Property: The sum of any number and zero is the original number. For example 5 + 0 = 5
-9x + 0.4 = 4
0.4 would have to be move to right (4 - 0.4)
which equals 3.6
-9x = 3.9
-9x/9 = 3.9/9
3,807,000 + 4,339,000= <span>8,146,000
or if you wanted it like this:
3,807,412 + 4,339,789 = </span><span>8,147,201 (8,147,201 Rounded)</span>
