Answer:
Well, we have to remember that we must use PEMDAS, or the order of operations, to solve the expression.
<em>Therefore, we must first either divide or multiply anything that is inside of the parentheses. (In this case divide)</em>
<em>Now solve what remains in the parentheses.</em>
<em>Finally, subtract 4 from 10 and get your answer:</em>
6
Answer:
The distance between the posts is feet.
Step-by-step explanation:
In the attached figure, let DB and AC be the posts and let AD be the wire attached to the top of the posts.
BC is the distance between the posts and we need to find BC.
Note that BC = DE
Also, EC = DB = 8m and AE = AC - EC = 17 - 8 = 9 m.
Now, in the right triangle ADE,
= (24+9) (24-9)
= 33(15)
= (3 × 11) × (3 × 5)
Since DE = BC,
Hence, the distance between the posts is feet.
