This isn’t hard, but I’ll help you. I won’t give the answer though. Simply do 61,061.83 divided by 12. That answer of that, divide that by two and you should have your answer
Answer:
A. x=16
Step-by-step explanation:
Similar triangles/ratios
1. Substitute 2x + 7 = 39, 4x + 1 = 65
2. Find size ratio between the two figures, 5:3
3. Check for similarity - 39 x 5/3 = 65
Basically, what you will do is 540 divided by 6
When you divide that, you should get, 90 parcels.
Hope this helps! Have a good rest of your day! c:
Answer:
D: {-1,2,9,-4}
R: {6,0,-3}
Step-by-step explanation:
domain are the x-values
range are the y-values
We can write this as:-
P(x) = + x^3 - 5x^2 - 25x + 125
There are 2 changes of real sign so by Descartes Rule of signs there are either 2 positive real roots or 0 positive roots.
P(-x) = - x^3 - 5x^2 + 25x + 125
There is just one change of sign so there is exactly 1 real negative root.
125 is a multiple of 5 so By rational root theorem 5 could be a positive root.
P(5) = 125 - 125 - 125 + 125 = 0 so one zero is 5
if we divide the polynomial by (x - 5) we get the quadratic
x^2 - 25
(x + 5)(x - 5) = 0
x = 5,-5
so the roots are 5 (multiplicity 2) and -5.
2 real positive zeroes and one real negative zero
