<span> Given polynomial x^2+8x-48 = 0</span>
<span>x^2+12x-4x-48 = 0</span>
<span>x(x+12)-4(x+12) = 0</span>
<span>(x+12)(x-4) = 0</span>
<span>x+12 = 0</span>
Subtract 12 from each side.
<span>x+12-12 = 0-12</span>
<span>x = -12</span>
<span>and x-4 = 0</span>
Add 4 to each side.
<span>x-4+4 = 0+4</span>
<span>x = 4</span>
<span>Roots are -12,4.</span>
Answer:
x=1
Step-by-step explanation:
you would change it to 5x-4(-3x+5)=-3, because you put the info for the first equation into the second equation.
5x-4(-3x+5)=-3
5x+12x-20=-3
17x-20=-3
17x=17
x=1
No If it was 4 to 3 then yes but 4 can't be multiplied by anything to equal 9
B)1,131.20 would be the answer. 1010x0.14=141.4x8=B
Answer:
Mean Is 3 , Median Is 3
Step-by-step explanation:
The mean is the usual average, so I'll add and then divide:
0 + 1 + 2 + 3 + 4 + 5 + 6 = 21 divide by 7 you'll get 3
The median is the middle value, so first you'll have to rewrite the list in numerical order: There are seven numbers in the list, so the middle one will be the answer which is 3
0 , 1 , 2 , 3 , 4 , 5 , 6
