Answer:
Since we have a^7 on the Numerator and after simplification... No "a" was left in the expression. It simply means that all a's in the numerator was eliminated and 2a's were left in the denominator.
To eliminate a^7 and still have 2a's as a remainder in the denominator... 'n' must be equal to 9
So
n=9

Answers
Correct question:
Triangle QRS has side lengths q = 5.1 and r = 9.8 . Angle S has a measure of 39 degrees. What is the length of side s?
Answer:
The length of side s is 6.66
Step-by-step explanation:
Given;
triangle QRS, with side length q = 5.1 and r = 9.8
angle between q and r = ∠S = 39⁰
Apply cosine rule to calculate the missing side "s";
s² = q² + r² - 2qr x Cos(S)
s² =5.1² + 9.8² - 2 x 5.1 x 9.8 x Cos(39)
s² = 122.05 - 77.68
s² = 44.37
s = √44.37
s = 6.66
Therefore, the length of side s is 6.66

i need help with this problem x²＋4x﹣30=﹣3x
Answers
Answer:
[tex]x^2 + 4x -30 = -3x\\x^2 + 4x +3x -30 = 0\\x^2 + 7x -30 = 0\\x^2 +10x -3x -30 = 0\\x(x+10) -3(x+10)\\(x-3)(x+10) = 0\\x = 3, -10[/tex]
first, move -3x to the other side of the equation.
your equation should look like this
x²+4x-30+3x=0
add like terms
x²+7x-30+=0
now factor.
(x+10)(x-3)=0
solve for x

which fractions are equivalent to 4/8? choose all correct answers (1/5) (2/6) (1/4) (1/2) (2/4)
Answers
Answer:
1/2, 2/4
Step-by-step explanation:
4/8 = (2/4) =1/2 (if you divide up and down by the same number)
so 4/8 = 1/2
next, let's simplify the choices we have: (1/5) (2/6) (1/4) (1/2) (2/4)
1/5 is already simplified
2/6 = 1/3
1/4 is already simplified
1/2 is already simplified
2/4 = 1/2
Which of these is equal to 4/8 (aka 1/2)?
Answer: 1/2 and 2/4

6. Let the function g be defined by g(x) = x4 – x3 – 9x2 + 9x. It is given that
x = 1 is a zero of the function g. Which of the following best represents the fully
factored form of the function g?
Answers
Answer:
A
Step-by-step explanation:
There is an x in all for terms that means that x = 0 is one of the factors and H is incorrect.
One of the remaining factors is x^2 - 9 which factors into (x - 3)(x + 3)
You are told that x = 1 is a zero which means x - 1 is a factor.
The answer is g(x) = x (x - 3)(x + 3) (x - 1) which is A

Which correctly describes a cross section of the square pyramid? Select three options. A square pyramid with 2 foot sides. A cross section parallel to the base is a square with side lengths of 2 ft. A cross section parallel to the base is a square with side lengths of less than 2 ft. A cross section perpendicular to the base through the top vertex is a triangle with the same dimensions as the triangular sides of the pyramid. A cross section perpendicular to the base through the top vertex is a triangle with different dimensions than the triangular sides of the pyramid. A cross section that is perpendicular to the base that does not pass through the top vertex of the pyramid is a trapezoid.
