Answer: Walking speed is about 5 kph, so it should take about 6 minutes to walk 500 meters.
Step-by-step explanation:
I'm gonna say that the answer if 12 (correct me if i'm wrong) so basically, following order of operations, you weed need to subtract something first, before that though, you need to find what number you can multiply 4 with to get 12, which the answer is 3. Knowing this, you need the subtraction problem to equal 3, so you add 3+2=5. x=5. so to put it in perspective, 5-2=3x4=12 hopefully i explained this well

Answer:
256
Step-by-step explanation:
Let the number be k
Thus, the equation can be written as:
x² – 32x + k
From the above,
a = 1
b = –32
c = k
The value of k can be obtained as follow:
b² = 4ac
(–32)² = 4 × 1 × k
1024 = 4k
Divide both side by 4
k = 1024 / 4
k = 256
Thus, 256 should be added to x² – 32x to make it a perfect square i.e
x² – 32x + 256
****Check****
x² – 32x + k
k = 256
x² – 32x + 256
x² – 16x – 16x + 256
x(x – 16) – 16(x – 16)
(x – 16)(x – 16)
(x – 16)² QED
