add -3x^2 to both sides 

add 9x to both sides 

add 4 to both sides

10x^2+10x-1 = 0 

we can plug into the quadratic formula : 

- we will get (-5+sqrt 35) / 10.  or (-5-sqrt 35) / 10

then you can plug these value into the other expression we can get 412 / 199

i think you should work on getting to know the quadratice equation more + simplfying equations in general

subtract 4x^2 from both sides 

- get 1x^2 

-add 17x on both sides = get 6x on the left side 

-subtract 6 from both sides = -2 on the right side 

if you do this you SHOULD get , 

x^2 + 6x - 2 = 0 

plug into quadratic formula (search up) : where ax^2 + bx + c is the formate ( a = 1.  b = 6  c = -2 )
we should get the solution: -3+sqrt(11) or -3-sqrt(11) and they represent a and b 

1/ (-3+sqrt(11))^3 + 1/ (-3-sqrt(11))^3 = 63/2 or 31.5

see if you can get it!

and someone please check my work

Srry mb gang 

a/3 + 1 = (( a+3) - (a^2 + 2))/a

a/3 + 1 =( a^2 - a - 1 ) / a 

a ( a/3 + 1 ) = a^2 - a - 1 

a^2/3 + a = a^2 - a -1 

a^2/3 = a^2 - 2a -1 

0 = (2a^2 - 2a) / 3  - 1 

then we can plug this equation into the quadratic equation, 

this gives us the answer 

(3+sqrt 15 )/2 or (3-sqrt15)/2 

please if anyone could check my answer that would be a fire 

(-24/5 ,  0 ) ? 

For the first one assuming that f(1) = 20-5 then im guessing the function is that when n increases the number of fives subtracted from 20 increases via the number of n (f(n)).

f(10) = -20-5-5-5-5-5-5-5-5-5-5 sooooo it has 5 tens 

4. f(1) =  - 6 as its a recursive function meaning you need to find the previous function number 

The equation of a triangle would be : (base x height)/2 

Please specify what you mean by equivalent formula as this the the best and easiest one to use 

I have noticed that :

vest = 4 letters = 20 dollars

socks = 5 letters = 25 dollars 

tie = 3 letters = 15 dollars 

blouse = 6 letters = 30 dollars 

MEANING: each letter is 5 dollars 

underwear = 9 letters = 9 x 5 = 45 

Hope this helps !

No solution I might be wrong  can someone confirm?

Half circle : r = 3 thus 1/2 x pi r ^ 2 = 14.135

4 x 5 = 20 

2 x 6 = 12 

4 x 7 = 28 

Thus the answer would be : 14.135 + 20 + 12 + 28 = 74.135

Break these questions into multiple basic shapes and then solve 

I think it would be -12, use the infinite geometric series equation :

For this equation, it would be: x / ( 1 - 0.5x^2)

set this equation to equal -12, you will get 2 different x answers x = -4/3 and x = 3/2, however, one is eliminated 

x = - 1 (1/3 )
