<span>jika xy = 0 , kemudian menganggap x dan y = 0
faktor 2x^2-9+7
(2x-2)(x-7)=0
2x-2=0
2x=2
x=1
x-7=0
x=7
</span><span>jika 1 = x1 dan 7 = x2 maka jawabannya adalah 1^2+7^2-4(1)(7)=22
</span>
jika 7 = x1 dan 1 = x2 maka jawabannya adalah
7^2+7^2-4(7)(1)=22
<span>jawabannya adalah 22</span>
Answer:
Number of Significant Figures: 4
The Significant Figures are 1 0 7 6
Since it's a square, the sides are all the same. This is going to be the equation.

Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) we have
----> equation A
----> equation B
substitute equation B in equation A

Applying property of exponents



therefore

Part 2) we have
----> equation A
----> equation B
substitute equation B in equation A

Applying property of exponents



simplify

therefore
