Answer:
1. -x²-15x-1
2. -33x⁷+10x⁶-14x⁵+4x⁴+11x²-5x+32
Step-by-step explanation:
-20x^2+5x+17 - (-19x^2+20x+18)
-20x² + 19x² + 5x - 20x + 17 - 18
-x² - 15x - 1
-20x^7+10x^6-5x+15 - (13x^7+14x^5-4x^4-11x^2-17)
-20x⁷ - 13x⁷ + 10x⁶ - 14x⁵ + 4x⁴ + 11x² - 5x + 15 + 17
-33x⁷ + 10x⁶ - 14x⁵ + 4x⁴ + 11x² - 5x + 32
Answer: 0.06x
Step-by-step explanation:
- An algebraic expression is an expression consist of integer constants, variables, and algebraic operations.
The given statement: A number is 30% of 20% of the number x.
The required algebraic expression would be:
30% of 20% of x
[we divide a percentage by 100 to convert it into decimal]
Hence, the required algebraic expression would be :
0.06x
Answer:
B. h=2A/(b1+b2) . . . . parentheses are needed
Step-by-step explanation:
Multiply the equation by the inverse of the coefficient of h. That coefficient is (b1 +b2)/2, so its inverse is 2/(b1 +b2). Parentheses are needed.
... 2A/(b1 +b2) = h

<em>Comment on the answer choices</em>
As written, <em>none of them are correct</em>. The denominator can only be written without parentheses if the division bar is horizontal, and so serves also as a grouping symbol.
You practically answered this one yourself by giving some of the equation we need already filled in. It would look like this: A(t)=500(1.04)^7. Start by taking 1.04 to the power of 7 to get A(t)=500(1.3159). Finish by multiplying to get
A(t)=$657.97
