The interest is $453.60.
The total amount includes principal + interest. The principal was 630 and the total amount was 1083.60.
1083.60 - 630 = 453.60.
Answer:
x = 1000
Step-by-step explanation:
To solve for x, you do the same thing to both sides to isolate x.
To isolate x in this equation, you divide both sides by 10.
10x = 10,000
10x/10 = 10,000/10
x = 1,000
I got 110 because 35+35=70 and 180-70=110. I added 35 to 35 because it says that AB=AD, so they should make congruent angles. So add the 35+35 and work from there.
So, just a note of formatting, to indicate something is an exponent of something else, use the carat (^) sign
for instance
x^3 means x cubed. x3 means 3x.
Anyways, though, let's factor.
You can factor out an x from each variable.
x(x^2-5x-14)
Now, to factor this, think of what will add to -5, and multiply to -14.
-7 and 2 work.
So, this factors out to
x(x-7)(x+2)
Choice D is the correct factorization.
