Answer:x=1/24
Step-by-step explanation:
To find 9x(x+6)-(3x+1)^2=1
Open the brackets
9x^2+54x-(3x+1)(3x+1)=1
9x^2+54x-(9x^2+6x+1)=1
9x^2+54x-9x^2-6x-1=1
54x-6x-1=1
Collect like terms
48x=1+1
48x=2
Divide through by 48
x=2/48
x=1/24
Answer:
182
Step-by-step explanation:
2( \frac{1}{2} \times 4 \times 6 ) + 2( 5 \times 10 ) + ( 6 \times 10 )
= {182cm}^{2}
First, factor the polynomial. Then, set each binary answer to zero and solve. Those are the values of x where the graph either crosses or touches the graph.
x²-9x+20
(x-5)(x-4)
x-5=0 | x=5
x-4=0 | x=4
The zeros are 4 and 5
