Answer:7h-2
Step-by-step explanation:
take away 2 indicates -2
7 times h indicates 7h
then you have a few ways to write this out either: -2+7h or 7h-2
both are correct!
Your answer is 21 for this one.
Hello there! I can help you! The formula for compound interest is P(1 + r)^t, where P= principal (initial amount), r = interest rate (in decimal form), and t = time (in years). Let's do this step by step. First off, we add the rate into 1. 4% is the interest rate (0.04 in decimal form). 1 + 0.04 is 1.04. Now, what we will do is raise that number to the 2nd power, because the time that elapses is 2 years. 1.04² is 1.0816. That's that. Now, multiply 7,500 to find the total amount of money. 1.0816 * 7,500 is 8,112. There. Toby's savings account balance in 2 years is £8,112.
Note: To solve for compound interest questions like it, add 1 to the percentage rate in decimal form, raise that number to a power based on the number of years (for example, raise the number to the 7th power if we are looking for the balance after 7 years), and then multiply that number by the starting amount. After you raise the number by a power, there may be a lot of numbers behind it. Whatever you do, DO NOT delete the number. Keep it there and multiply it by the principal.
Distribute each term in one parenthesis to the other terms in the other parenthesis.
(x - 2) (2x + 3)
First, distribute x. When distributing, multiply
x(2x) = 2x²
x(3) = 3x
Next, distribute the other term, -2. Remember to change the signs.
-2(2x) = -4x
-2(3) = -6
-------------------------------------------------------------------------------------------------------------------
2x² + 3x - 4x - 6
Combine like terms
3x - 4x = -x
2x² - x - 6
-------------------------------------------------------------------------------------------------------------------
2x² - x - 6 is your answer
hope this helps
We know that
[<span>the area of the rectangle]=L*W
L=1/3 yd
W=2/3 yd
</span>[the area of the rectangle]=1/3*2/3---------> 2/9 yd²
the answer is 2/9 yd²
