12. The white triangle drawn on the road sign in the picture has a height of 8" and a base of 5". Which formula would be correct to find the area of this triangle? O A = {(8+8)(5+5)
O A= {(8)(5)
O A=2 (8)(8) + 2 (5)(5)
O A= 2(8)+2(5)

Step-by-step explanation:

I think you did not copy the correct information of your answer options here.

because, as you wrote the 4 options, none of them are correct.

remember, the area of a triangle is base times height divided by 2

A = (b × h) / 2

given the numbers in the problem statement

b = 5, h = 8

A = (5 × 8) / 2 = 40 / 2 = 20

you need to pick the answer option in your original document that would lead to 20.

none of the 4 options you gave me here would result in 20. so, there must be something wrong with them.

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
