Answer:
v=−5
Step-by-step explanation:
2v + 18 = 16 - 4(v + 7)
2v+18=16−4(v+7)
2v+18=16+(−4)(v)+(−4)(7)(Distribute)
2v+18=16+−4v+−28
2v+18=(−4v)+(16+−28)(Combine Like Terms)
2v+18=−4v+−12
2v+18=−4v−12
Add 4v to both sides.
2v+18+4v=−4v−12+4v
6v+18=−12
Subtract 18 from both sides.
6v+18−18=−12−18
6v=−30
Divide both sides by 6.
6v
/6
=
−30
/6
v=−5
Consider the polynomial identity (difference of squares):
(x+y)(x-y) = x² - y²
Set x =7 and y = 2 to obtain
(7+2)*(7-2) = 7² - 2²
9*5 = 49 - 4
45 = 49 - 4
This is the result required, obtained by using difference of squares.
Answer: Difference of squares.
Answer:
See below.
Step-by-step explanation:
The last step is incorrect. When we divide both sides by a negative the inequality is flipped. The answer is x < -1/2.
Also they omitted the other possibility that the expression in the vertical lines could be negative.
We also have the inequality
- 4x + 1 < - 3
-4x < -4
x > 1.
