Answer:
see explanation
Step-by-step explanation:
Given
(x - 3) × (x + 4) = 0, that is
(x - 3)(x + 4) = 0
The zero product indicates that (x - 3) = 0 or (x + 4) = 0
x - 3 = 0 ⇒ x = 3
x + 4 = 0 ⇒ x = - 4
Thus if x = 3, then
(3 - 3)(x + 4) = 0 × (x + 4) = 0
Similarly if x = - 4 the output is zero
It’s a ! you add both of the numbers to get your missing perimeter.
I’m very sorry if it’s wrong but this is what I believe! stay safe
-2b + 7 > 27.5
- 2b > 27.5 - 7
- 2b > 20.5
b < - 10.25
Answer:
Computer disks are $4 each
Notebooks are $3 each
Step-by-step explanation:
For the first equation
<em>$4 x 2 disks = $8</em>
<em>$3 x 3 notebooks = $9</em>
<em>$9 + $8 = </em>$17
For the second equation
<em>$4 x 5 disks = $20</em>
<em>$3 x 4 notebooks = $12</em>
<em>$20 + $12 = </em>$32
