The answers are that the number can equal -4 or 1.
You can find this by setting the number equal to x.
x^2 (The square of a number) + 3x (three times a number) = 4
x^2 + 3x = 4 ---> subtract 4 from each side
x^2 + 3x - 4 = 0
Then you can factor this to find the answers
(x - 4)(x + 1) = 0
Set both equal to 0 and solve.
Well, I Don't See The Answer Choices, But The Next Step Is Most Likely To Subtract 8 From Both Sides.
Answer:54
Step-by-step explanation:
Pentagon has 5 sides
n=5
Sum of interior angles=180(n-2)
Sum of interior angles=180(5-2)
Sum of interior angles=180x3
Sum of interior angles=540
Size of each interior angle =540/n
Size of each interior angle =540/5
Size of each interior angle=108
x=108/2
x=54
Answer:
(f+g)(x) = 3x² + (3/2)X - 9
Step-by-step explanation:
f(x) = 1/2*x - 3
g(x) = 3x²+x-6
then (f+g)(x) i f(x) + g(x)
1/2*x - 3 + 3x²+x-6
3x² + 1.5X - 9
3x² + (3/2)X - 9
