Answer:
Step-by-step explanation:
First find the area of the 2 bases, the triangles. 6x8= 48\2= 24 + 24= 48
Now find the area of each rectangle, which there are three of them. 8x14= 112, 6x14= 84, 10x14= 140
Now add all rectangles and triangles together 48+ 112+ 84+ 140= 384

Answer:
5x+3y
Step-by-step explanation:
2x+3x=5x since they have the same variable.
y+2y
1y+2y u can put a 1 so that would be 3y
5x+3y
Answer:
15
integers from 1 to 9 have only one number each, so in total 9 numbers. integers from 10 to 12 have 2 numbers each, 3*2=6. 9+6=15
Notice that the triangle is a right triangle, because of the right angle. By the Pythagorean Theorem,
. Then
, d. 8 m
The other angle would be 118°
The three angles of a triangle must add up to 180°.
