Answer:
1. 36 sq un
2. 40 sq un
3. 20 sq un
Step-by-step explanation:
The answer for number one is 36 square units because the rectangular area is 24 sq un and the triangular area is 12 sq un so I added them to get 36 sq un. The second answer is 40 sq un because if you cut the shape into 2 shapes you get 2 equal trapezoids. Each trapezoid is 20 sq un so I multiplied it by two to get 40 sq un. The third answer is 20 because the side triangles are 2 sq un each and the square on the bottom is 16 sq un. By the way, sq un means square units lol.

Answer:
BC = 25
Step-by-step explanation:
AB = AC since it is an isosceles triangle
4x+1 = 2x+23
subtract 2x from each side
4x-2x+1 = 2x-2x+23
2x +1 = 23
subtract 1 from each side
2x+1 -1 = 23-1
2x = 22
divide by 2
2x/2 =22/2
x =11
BC = 3x-8
BC = 3(11) -8
BC =33-8
BC = 25
Multiply denominator by whole number then add that number to the nominator. Which would be 5 times 1 plus 3. SO 5+3 IS 8 and you keep the denominator so the first one is 8/5
It should be the second one:ab=ed
