Factor out the trinomial. Find factors of x² and 6 that would, when added, give you 5x
x² = x * x
6 = 3 * 2
(x + 3)(x + 2) are your binomials.
To solve for x, set each parenthesis = 0
x + 3 = 0
x + 3 (-3) = 0 (-3)
x = -3
x + 2 = 0
x + 2 (-2) = 0 (-2)
x = -2
x = -3, -2
hope this helps
Answer:
4 . The answer is no .
5 . x=1

7. There's no answer to this question .
Step-by-step explanation:
___________________
4. solution :
-20(2-4) = 2((5×-4) -4) =
-40 = -48 × impossible

5. solution :
-3+4x+12x+24 = 28x +12-3
-3+24-12+3=28x-12x-4x
27-15=12 = 2x - 16x =12x
12 = 12x
x =1

6. solution :
24-3x+9-6 = -8x+20+5x+7
8x-5x-3x = -24-9+6+20+7
0=0
x can be every number you think because they are always equal to each other .
examination :
if you consider x as 1 :
24-3+9-6=-8+20+5+7
24=24
or if you consider x as 2 :
24-6+9-6 = -16+20+10+7
21 = 21

7 . solution :
3(x-2) = 3x+4
3x-6 = 3x+4
3x-3x = 10
0 = 10
if you consider x as 1 :
3-6 = 3+4
-3 = 7 × impossible .
Answer: (10 - 6i)/5
(x + yi) + (4(x + yi) + 6i) = 10
⇔ 5(x + yi) + 6i = 10
⇔ 5(x + yi) = 10 - 6i
⇔ x + yi = (10 - 6i)/5
Step-by-step explanation:
Graph that y= equation then on your calculator find what X is when y is 0 using 2nd-->calc-->zero, then follow instructions
you can immediately eliminate options 2 and 3 because volume doesn't require width or fencing
volume would be the capacity (or how much something can hold) so it is the first option
