Answer:
43.8
Step-by-step explanation:
Remark
Are there ever a lot of assumptions!!
- The rectangles are all the same size
- the triangles are the same size
- The rectangles are indeed rectangles.
- The triangles are isosceles.
- The two equal sides are both equal to the width of the rectangles.
Area of the rectangles
A = L * W
L = 4 m
W = 3 m
Area = 4*3 = 12
There are 3 rectangles so the total area = 3*12 = 36
Area triangles
Area = 1/2 b * h
b = 3
h = 2.6
Area = 1/2 * 2.6 * 3
Area = 1/2 7.8
But there are 2 of them so the area for the 2 is
Area = 2* 1/2 7.8
Area = 7.8
Total area = 36 + 7.8
Total area = 43.8

Answer:
4x^2+4x-1
Step-by-step explanation:
6 numbers per cube
if one is a 1, then the other one has to be a 2, 4 or 6 to be an odd sum
1+2=3, 1+4=5,1+6=7
since there are 3 numbers you can get that would be a 3/6 ( reduce to 1/2) probability
so 1/2 probability
Arithmetic sequences have a common difference (addition)
geometric sequences have a common ratio (multiplication)
Answer: x=12
Step-by-step explanation:
5x-15=2x+21(AIA)
3x-15=21
3x=36
x=12
