Answer:
A
Step-by-step explanation:
6x- 3x + 6=18
6(4)- 3(4) + 6=18
24-12 + 6=18
12 +6=18
18=18
Answer:
849.24 cm²
Step-by-step explanation:
we know it is a cube so to find the surface area of each square you do
12x12=144 and there are 5 sides so 144x5=720
We know sides of the squares are 12 cm so half of that (6) would be the bottom of the triangle
Now using pythagorus you would do a²+b²=c²
15²+6²=c²
225+36=c²
√261=√c²
16.15=c this only half of one of the sides of the pyramid so you would times 16.15 by 8 to equal 129.24
now add 720+129.24=849.24 cm²
Answer
So if you want to get the area of a parallelogram you should do length x width
So 3.7 x 12.5= 46.25
I’m sorry if this is a wrong answer but this is what the teacher told us
