First

determine if this equation were factorable, it's not for this one
so I use quadratic formula, try to search the formula online


<span>x ≈ −2.72 and x ≈ −0.28 is the solution</span>
1 + 1 + 1 + 2 = 5
5 x 9 = 45
Therefore, the total number of km is 45.
Answer:
Step-by-step explanation:
salut :
en utilisant le theorem de Pythagore on obtient :
AC²= AB² + BC²
(a+5)² = 7²+a²
a²+10a+25 = 49+a²
10a+25 =49
10a =24
donc : a = 24/10 = 12/5 = 2.4 unit
Answer:
4x-5
Step-by-step explanation:
first make the equation easier 8x -1(5+4x)
then simplify with the parenthesis 8x -5-4x
then combine like terms 4x-5
there is you answer
Answer:
