• Expand (2a + b)²:
(2a + b)²
= (2a + b) · (2a + b)
Multiply out the brackets by applying the distributive property of multiplication:
= (2a + b) · 2a + (2a + b) · b
= 2a · 2a + b · 2a + 2a · b + b · b
= 2²a² + 2ab + 2ab + b²
Now, group like terms together, and you get
= 2²a² + 4ab + b²
= 4a² + 4ab + b² <——— expanded form (this is the answer).
I hope this helps. =)

To compare these two values, we need them to be in the same form.
To convert 20% into a decimal, we divide 20/100, or 0.20.
When comparing decimals, we know that 0.2 > 0.02.
Therefore, 20% > 0.02. (20% is greater than 0.02)
<span><span>A = p (1+<span>r/n</span><span>)^<span>nt</span></span></span><span>p - initial amount which is 200
r - interest rate which is 0.025 written in decimal form
n - is the number of compounding a year, in this case is 2 because it's every six monthand
t is the year which is one in your case
A = 200 (1 + 0.025/2)²

Answer:
Step-by-step explanation:
The total number of caps or shirts needed will be equal to the total amount of people in the system.
We can multiply the amount of caps and shirts by their price to get the total price needed.
We can substitute one equation into another to solve for x.
Now we put our x value back into the other equation to get y
Now we substitute both of our values into our second equation to verify that they are correct
So correct!
Answer:
Yes
