Answer:
x=-10/23
Step-by-step explanation:
-23x=10
x=10/-23
x=-10/23
I use a bit of a different looking formula.
A(t)=P(1+r/n)^nt
P=amount of money. (500)
r= rate (in decimal. 4%=0.04)
n=number of times per year (1 in this problem)
t=amount of time. (5 years)
Plugged in it looks like this:
A(t)=500 (1+ 0.04/1)^1x5
Then I put it into my calculator like this:
0.04/1+ 0.04
Then add one to the above answer:
0.04+1=1.04
Then raise the above answer to the 1x5:
1.04^5=1.2166......
Then multiply the above answer by 500:
1.2166.... x 500=608.3264512
She has $608 after 5 years.
Hope this helps, let me know if you have any questions.

Part 1
Find the length side AB
we know that
----> by SOH (opposite side divided by the hypotenuse)
substitute the given values
solve for AB
Part 2
Find the length side AC
we know that
----> by TOA (opposite side divided by the adjacent side)
substitute the given values
solve for AC

Answer:
Step-by-step explanation:
x^2 + 10x + 5 - 30 = 0
x^2 + 10x - 25 = 0
x^2 + 10x = 25
x^2 + 10x + 25 = 25 + 25
(x + 5)^2 = 50 <====
