From 100, do 148-100 = 48. then 48 add 7 to make 55. that means the answer is 55 mazes left to complete.

another way would be 148 - 93 = 

148
 <u>93</u>  -

2x² + 4x + 4 + x² + 1 = 180
Tasya [4]

Step-by-step explanation:

2 {x}^{2}  + 4x + 4 +  {x}^{2}  + 1 = 180

3 {x}^{2}  + 4x + 5 = 180

{3x}^{2}  + 25x - 21x - 175 = 0

x \times (3x + 25) - 7(3x + 25) = 0

(3x + 25) \times (x - 7) = 0

3x + 25 = 0 = x - 7 = 0

x =  -  \frac{25}{3}  = x = 7

= x_{1} =  -  \frac{25}{3} . \:  \:  x_{2} = 7

What are zeros of the function? What are there multiples? f(x) = 4x^3 -20x2 + 24x
bixtya [17]
When X=0, the function would be:

<span>f(x) = 4x^3 -20x2 + 24x
0= </span><span>4x^3 -20x2 + 24x       ----->divide all by x
</span>x(4x^2 -20x + 24)  =0     ------> split -20x into -12x and -8x
x(4x^2 -12x -8x + 24)
x{4x(x-3)  - 8(x -3}
x(4x-8) (x-3)
x1= 0
x2= 8/4= 2
x3= 3

How do I solve this problem
guapka [62]
You first subtract 1/5 from both sides
3/4-1/5 = 11/20 
3/2x=11/20

now you multiply 2/3 on both sides since you have to get x

11/20 * 2/3 
x = 11/30
