The last one is correct “|-100|>50
Answer:
ab + cd-bd-ac = a(b-c)+d(c-b)
Step-by-step explanation:
ab+cd-bd-ac
Let us first bring the like terms together
Like terms are those terms which have same variables and same exponents also. Hence in this case we do not any like terms.
Hence we will take those two terms together which has atleast one same variable
ab and ac
cd and bd
ab-ac+cd-bd
now taking a as GCF in first two terms and d as GCF in last two terms
a(b-c)+d(c-b)

Answer:
The answer would be -9 and -3 which would be B and D
Step-by-step explanation:
Answer:
207m
Step-by-step explanation:
We apply the cosine rule to find the distance between the other two subs.
Let this distance be x, then the cosine rule gives:
We simplify to get:
Simplify
Take square root;
To the nearest meter the distance between them is 207m
