Answer:
Tell her to do more practices in math. You can also recommend her here at Brainly if she finds hard questions to solve.
Step-by-step explanation:
5x-2+3x=17+12x-23 combine like terms
8x-2=12x-6
-8x -8x
-2=4x-6
+6 +6
4=4x divide each side by 4
x=1
Answer:
(x+3)(x-4)^2
Step-by-step explanation:
= (x+3)(x^3-5x^2-8x+48)/(x+3)
= x (x^3-5x^2-8x+48)/(x+3)
= x^2-8x+16
= (x+3)(x-4)(x-4)
= (x+3)(x-4)^2
Answer:

Step-by-step explanation:
The limit is:

so, you have an indeterminate result. By using the l'Hôpital's rule you have:

by replacing, and applying repeatedly you obtain:

hence, the limit of the function is -1/14
Answer:
578.3 ft²
Step-by-step explanation:
slope lengths are
L = √(11² + (13/2)²) = √163.25
A = (13 + 2√163.25)(15) = 578.307970...
