The difference between the square roots of a number 30 is 15 I am pretty sure it is 15
(13x+14)(6x-5)=0
78x²-65x+84x-70=0
78x²+19x-70=0
It was equation.
______________
Factoring⇒ a×c=78×(-70)=-5460
84×(-65)=-5460
84+(-65)=19 which is b

6x(13x+14)-5(13x+14)=0
(13x+14)(6x-5)=0
13x+14=0 6x-5=0
13x=-14 6x=5
x=-14/13 x=5/6
Two solution X=-14/13;5/6
Answer:
x = 2
Step-by-step explanation:
x^3 + 1 = 9
x^3 = 8
= ![\sqrt[3]{8}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D)
x = 2
Answer:
17.75x + 5.25
165
x
9
Step-by-step explanation:
The total cost can be represented by 17.75x + 5.25, where x is the number of people.
They can only spend a maximum of $165, so a less than or equal sign has to be used.
The inequality will be 17.75x + 5.25
165
Now, solve for x:
17.75x + 5.25
165
17.75x
159.75
x
9
So, x
9 is the answer, meaning 9 people or less can go to the amusement park.
there are 360 degrees in a complete circle
360/18 = 20
so the answer is C
