Answer:
yes
Step-by-step explanation:
(5_3)^2+2(0)=4
substitute with the 5 to x and 0 to y
<span>x² + y² + 14x − 4y − 28 = 0
x² +14x +y² - 4y =28
x²+2*7x +7² -7² + y² - 2*2y +2² - 2² = 28
(x+7)² + (y-2)² -7²-2² =28
</span>(x+7)² + (y-2)²=28+49+4
(x+7)² + (y-2)² =81 is the answer.
Answer:
a=-6
Step-by-step explanation:
2(3-a)=18
3-a=18/2
3-a=9
a=3-9
a=-6
Answer:
i dont know what you mean by ignore this and it looks like you got it
Step-by-step explanation:
Answer:Given expression : a(x-y)-b(x-y)
Now, (x-y) is common in both terms.
First factor is (x-y).
∴a(x−y)−b(x−y)=(x−y)(a−b)
