Step-by-step explanation:
Answer with Step-by-step explanation:
Let A is non-singular
We have to prove that is unique.
Suppose B and C are inverse of A such that
and AC=I
By using property
Hence, the inverse of A is unique.
Answer:
211 × 9 is 1899 so rounding to nearest thousands would be 2000
Answer:
I have to say it's either D or A. I'm not really good with math though, good luck!
Surface area is just the area of all these 4 triangles plus the rectangle.
First we can find the area of the rectangle.
Half of the length is 28 cm, so the full length must be 28 * 2 = 56 cm.
The base for the left and right triangles are 27. The heights would be the net length minus half the length of the rectangle:
Calculate the area:
We have two of these triangles.
Now do the other two pair of triangles. The bases for them are 28 + 28 = 56 cm. The heights would be the net width minus the width of the rectangle:
Now find the area:
We have two of these triangles.
Add all the areas together:
