Answer:
12x-13
Step-by-step explanation:
multiply the perantheses first, -8+12x-5, the distributive property states we can only add same exponents (x^2 can add into 3x^2 but not 3x) so we add -8 and -5 to get 12x-13
Answer:
Ok
Step-by-step explanation:
-5x⁽²⁺³ˣ) - 2x(x-4)
Let's seperate the equation, and do the first half first.
-5x ⁽²⁺³ˣ⁾
Multiply -5x with 2.
Then, multiply 3x with -5x.
That gives us: -10x - 15x²
Now, let's do the second half.
2x(x-4)
2x²-8x
Now, let's put them together.
(-10x-15x²) - (2x²-8x)
Add like terms.
(-2x² - 15x²) - (-8x - 10x)
Simplify.
-17x² - (-18x)
-17x² + 18x

Answer:o find amount we use formula:
A=P(1+rn)n⋅t
A = total amount
P = principal or amount of money deposited,
r = annual interest rate
n = number of times compounded per year
t = time in years
In this example we have
P=$4500 , r=7% , n=2 and t=9 years
After plugging the given information we have
AAAA=4500(1+0.072)2⋅9=4500⋅1.03518=4500⋅1.857489=8358.7
STEP 2: To find interest we use formula A=P+I, since A=8358.7 and P = 4500 we have:
A8358.7II=P+I=4500+I=8358.7−4500=3858.7
so the answer is 8358.7 and the interest is 3858.7
