Answer:
<em>- 2 </em>
<em> + 7x²y - 24y² </em>
Step-by-step explanation:
( 5 - 5x²y + 9y² ) - ( 7 - 12x²y + 33y² ) =
5 - 5x²y + 9y² - 7 + 12x²y - 33y² =
( 5 - 7 ) + ( - 5x²y + 12x²y ) + ( 9y² - 33y² ) =
<em>- 2 </em><em> + 7x²y - 24y²</em>
Answer:
(a)
and 
Step-by-step explanation:
Required
Which of a to d has no solution
(a) and
We have:
Sole for m
Divide by 6
So, we have:
and
implies that: m = -6,-7,-8,-9.....
implies that m = -3,-2,-1,0.....
<em>Hence, there is no solution</em>

Answer: 129
Step-by-step explanation: First find the area of the circle. Since we know the area of a circle is πr² (pi multiplied by the radius squared) we can find the area of the half circle. The radius is 5 (because radius is half of the diameter)
Area=3.14(5)²
=3.14(25)
=78.5
But since this is just a half circle, divide this by 2
That will get 39.25
Then add this to the area of the rectangle (L*W) which is 90
That will get about 129
