The time taken by Jill and Cheryl to double their money is 12 years and 18 years respectively.
<h3>What is Algebra?</h3>
Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
Jill invested $500 in an account with a compound interest rate of 6%.
Cheryl invests $600 in an account with a compound interest rate of 4%.
The number of years each doubles their money. Using the relation of 72.
where r is the interest rate and t be the time
The time for the Jill will be
The time for the Cheryl will be

Answer:
h = 2
Step-by-step explanation:
I'm assuming your periods are multiplication signs.
(h + h) X (h X h) = 16
When adding two variables like the first set of parentheses, it would become 2h. When multiplying two like variables, you add the exponents. h is the same as writing h¹. So h¹ x h¹ gives you the answer of h².
So now your equation would look like:
2h X h² = 16
As above, when you multiply two like variables you would add the exponents. Also if any number are in front of the variable you would multiply those numbers. So you have 2h¹ x 1h² and that would be 2h³. If it had been
2h¹ x 2h², your answer would have been 4h³.
But so far you have 2h¹ x 1h² = 16
2h³ = 16
Dividing both sides by 2 you get
h³ = 8
To find h you have to take the cubed root of 8. What number multiplied by itself 3 times gives you 8? 2 x 2 x 2 = 8 2 x 2 = 4 and x 2 = 8.
h = 2
If you put this into the original equation you have:
(2 + 2) x ( 2 x 2) = 16
( 4 ) x ( 4 ) = 16
Answer:
Its the second one

I used slope to solve it
Answer:
x = 9
Step-by-step explanation:
You have to use the Secant Segment theorem:
AB * AC = AD * AE
This means that the external piece of the secant times the whole secant for one is equal to the external piece of the secant times the whole secant for the other.
Now, setup an equation:
8(x + 8) = 4(30 + 4)
Simplify:
8x + 64 = 120 + 16
8x = 72
x = 9

Evaluate the expression 
where m=5 and n=4
We replace the value of m and n to evaluate
m=5 and n=4
50 + 4 = 54
The value of the given expression is 54 when m=5 and n= 4
