6. over 5 straight plays, a football team gained 8 yards, lost 4 yards,
gained 7 yards, gained 3 yards, and lost 11 yards. what is the team's
position now compared to their starting position?

The position of the team now is 3 yards from their starting position

Step-by-step explanation:

- Lets explain how to solve the problem

- There is some words we can translate them in mathematics to (+)

  sign and (-) sign as gain and loss

- Gain means add the value and loss means subtract the value

* Lets solve the problem

- There are 5 straight plays for a football team

- The football team gained 8 yards , then lost 4 yard , then gained

  7 yards , then gained 3 yards and finally lost 11 yards

- We need to know the position of the football team now compared

 to their starting position

- Assume that they started at 0 position and when they gained

  yards we add them and when they lost yards we subtract them

∵ They gained 8 yards

∴ 0 + 8 = 8

∵ They lost 4 yards

∴ 8 - 4 = 4

∵ They gained 7 yards

∴ 4 + 7 = 11

∵ They gained 3 yards

∴ 11 + 3 = 14

∵ They lost 11 yards

∴ 14 - 11 = 3

* The position of the team now is 3 yards from their starting position

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

answer: the answer is b. i think hope i got it correct
