Answer:
42 units squared
Step-by-step explanation:
break it up into smaller shapes. if you split the big shape at y = 2 and at y=-2, you'll get two triangles and one rectangle.
so the area of the rectangle = l x w
= 4 x 7
= 28
the area of the triangle is ( l x w )/2
= (7 x 2)/2
= 7
the other triangle is the same too
so the area of that is also 7.
now add all areas,
7+7+28 = 42
All numbers that end in 5 are not divisible by 10. So this is false.
The answer would be A.
Deena is correct because that is not a rational number
Irrational numbers are numbers that are crazy and don’t have an end to them. Example would be pi because it goes on forever and ever. But it you have something that is straight to the point like 2.3 or -4/7 these are RATIONAL because they have an end and are “contained”, this goes for numbers that are repeating too.. if you have like 2.3repeating, then this is also rational because you know what the number is, and it is consistent.
I hope this helps explain rational and irrational a little better :)
