Answer:
Step-by-step explanation:
<u>Two-digit numbers are:</u>
<u>Sum of them is:</u>
- 10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 528
- 22a + 22b + 22c = 528
- a + b + c = 528/22
- a + b + c = 24
The only option of three different digits with the sum of 24 is 7, 8 and 9
Answer:
8) Parallelogram.
10) Point W.
Step-by-step explanation:
8) Give another name of plane V.
As shown the plane represents A flat shape with 4 straight sides where opposite sides are parallel and also opposite sides are equal in length.
So, plane V represents parallelogram
10) Name a point that is not coplanar with R, S and T.
Coplanar points are the points which all lie in the same plane.
So, as shown:
R, S and T are coplanar points, they all lie in the plane V
So, the point which doesn't lie in the plane V is the point W
So, <u>the point W</u> is not coplanar with R, S and T.
A) 19m because 3 times 6 is 18 then you add m, which would be 19m
