Answer: 5 toy cars
Step-by-step explanation: Hi there.
First, add the number of cars that he had, the number of cars he bought, and the number of cars he received for his birthday: 13+22+21=56
Then subtract your answer (56) from the number of toy cars he gave away to Wayne and his sister: 56-46-5=5
Therefore, Darrel has 5 toy cars left.
Have a nice day! :)
Answer :
B. 4x²(2x-3)(x+6)
4x²(2x-3)(x+6)
4x²(2x²+12x-3x-18)
4x²(2x²+9x-18)
8x⁴+36x³-72x²
10.4375
12.875×2=25.75 46.625-25.75=20.875 20.875÷2=10.4375
<h3><u>d^3 - 4bd^2 + 16b^2d - 64d^3 is the expanded binomial.</u></h3>
The binomial theorem involves Pascal's triangle, and essentially gives you the coefficients for the formula you're going to use to expand it.
In this case, the coefficients will be 1, 3, 3, and 1.
We can set up our formula like this:
(a + (-b)) = a^3 + a^2b + ab^2 + b^3
Now we can just plug in our values:
(d + (-4b))^3 = d^3 + d^2(-4b) + d(-4b)^2 + (-4b)^3
Now, we can simplify the equation.
(d + (-4b))^3 = d^3 - 4bd^2 + 16b^2d - 64d^3
