Answer:
a- (x-7)(x+9) | b- 193*207 | c- 242*258
Step-by-step explanation:
a)
x^2+2x-63.
the middle number is <em>2 </em>and the last number is <em>-63</em>.
You would have 2 numbers that add to 2 and multiply to -63.
Those numbers are -7 and 9.
so (x-7)(x+9).
b)
((200)-7)((200)+9)
(193)(209).
You can check this by multiplying 193 by 209 and then doing (200)^2+2(200)-63. Both would equal 40337.
c)
2(x-7)+2(x+9)=1000
(2x-14)+(2x+18)=1000
4x+4=1000
4x=996
x=249.
((249)-7)((249)+9)
(242)(258)
Answer:
Step-by-step explanation:

First, subtract 8x from both sides:
Add 39 to both sides:
Divide both sides by 4:
And we're done!
