just had this on a quiz
Answer:
-102
Step-by-step explanation:
2x3=6
6+7 = 13
13x2=26
26-4=22
2x2=4
4+4=8
8x-10=-80
-80 - 22 = -102
Hope this helps
To subtract the given expressions, first, simplify each expression separately by combining like terms. Then subtract the second expression from the first expression by distributing a negative sign and adding it to the first expression.
To subtract the given expressions, (2x^3+7x^2-4) - (2x^2+4x-10), we need to simplify each expression separately and then subtract them. First, combine like terms within each expression. Then, subtract the terms of the second expression from the first expression. This can be done by distributing a negative sign to each term in the second expression and then adding it to the first expression.
So, (2x^3+7x^2-4) - (2x^2+4x-10) = 2x^3+7x^2-4 - 2x^2-4x+10.
Combining like terms, we get 2x^3+(7x^2-2x^2)+(-4-4x)+(10). Simplifying further, we have 2x^3 + 5x^2 - 4x + 6. Therefore, the result of the subtraction is 2x^3 + 5x^2 - 4x + 6.

Answer:
≈ $937
Step-by-step explanation:
to answer this, we have to use the compound interest formula which is:
A = P(1 + r/n)^nt
the meanings of each variable are:
A = result
P = principal amount
r = rate (in decimal form)
n = the number of compound periods (eg: annually, quarterly, etc)
t = time
in the word problem, we need to solve for A. we are given P, r, n, and t.
P = 800
r = 0.02 also known as 2%
n = 1 keyword being annually which is equal to the value of 1
t = 8
we can plug these values into the formula:
A = 800(1 + 0.02/1)
we can use a calculator to calculate this easier but ill break it down:
A = 800(1 + 0.02/1)
A = 800(1.02)
A = 800(1.02)
A = 800(1.17165938)
A ≈ 937.327
we can round 937.327 to the nearest dollar which is $937
Carl would have earned $937 over the course of 8 years
