45-12=33
Step-by-step explanation:
you subtract 45 by 12 and get 33
Answer:
20
Step-by-step explanation:
The distance between two points is found by
d = sqrt( ( x2-x1)^2+(y2-y1)^2
= sqrt( ( 10- -6)^2 + (-4 -8)^2 )
= sqrt( (16^2 + (-12 )^2)
= sqrt(256+144)
= sqrt(400)
= 20
Answer:
The sum of a rational number and an irrational number is <u>ir</u><u>rational</u> number.
Answer:
If a line is perpendicular to another line, that means that the slope is completely opposite that of the original line. The first thing that we do to the slope is we negate the number which means that if we have a slope of 
our slope because 
in this step. In our case our slope is so in this step it becomes .
Moving onto the second part which is to get the reciprocal of the number which means that if we have 
then we would switch it to 
. In our case our number is so we would make that into a fraction like this 
.
In conclusion, our final slope of the perpendicular line is .

Answer:
I believe its 16.
Step-by-step explanation:
Because 2 x 2 (for the square) is 4. 2 x 3 is 6, and 6 divided by 2 is 3. And 3 x 4 (for all the triangles) is 12. So 12 + 4 is 16. So the surface area should be 16.
