Answer:
primero debemos resolver la ecuacion sumamos 3d mas 10d luego pasamos el mumero 8 al otro lado entonces se convertira en negativo 8 el resulatdo de esta ecuacion sera 13d elevado al cubo =-8
13d^{3}=-8 entonces
entonces remplazamos en la formula cuadratica 3d=a 0=b -8=c y lo rremplazas en la formula cuadratica
Step-by-step explanation:
First we must solve the equation we add 3d plus 10d then we pass the number 8 to the other side then it will become negative 8 the result of this equation will be 13d cubed = -8
13d 3 = - 8 then
then we replace in the quadratic formula 3d = a 0 = b -8 = c and you replace it in the quadratic formula
Answer:
The number of hours did Sarah practice more than Leilani is 
hours .
Step-by-step explanation:
Given as :
The time for which Leilani practiced piano = 
hours
The time for which Sarah practiced piano = 
hours
Let the number of hours did Sarah practice more than Leilani = T hours
<u>Now, According to question</u>
The number of hours did Sarah practice more than Leilani = hours - hours
Or, T = 
hours
Or, T = hours
So,The number of hours did Sarah practice more than Leilani = T = hours
Hence, The number of hours did Sarah practice more than Leilani is hours . Answer
Answer:
y=1x+-3
Step-by-step explanation:
using rise over run we can see that we go up one from a point and over 1 from a point making our slope 1. then you you find the y-intercept and here that is very easy because we can clearly see the line pass through -3 on the y axis. the just substitute in your values to get y=1x+-3
Answer:

Step-by-step explanation:
Given 2 sides of a triangle then the third side x is in the range
difference of 2 sides < x < sum of 2 sides
(11)
given 2 sides 2, 6 , then
6 - 2 < x < 6 + 2
4 < x < 8
(12)
Given 2 sides 4, 12 , then
12 - 4 < x < 12 + 4
8 < x < 16
(13)
Given 2 sides 2, 11 , then
11 - 2 < x < 11 + 2
9 < x < 13
