Answer:
So the model should represent either 
or
(its equivalent and simplified form.
Step-by-step explanation:
1) Originally the question wants to represent this quotient as tiles.
So,
We can still simplify it, but since we're dealing with 100 x 100 squares let's keep it this way
2) So the model should represent either or (its equivalent and simplified form.
Answer:
C. 15
Step-by-step explanation:
Small triangle is similar to larger one so we can use the similarity ratio to solve the question:
CE/CA = DE/AB
4/12 = 5/AB cross multiply expressions
4AB = 60 divide both sides by 4
AB = 15
Answer:
easy-peasy
Step-by-step explanation:
Perimeter:
P=2(a+b)
P=2(50+70)
P=2(120
P=240
Area:
A=50*70
A=3,500
I really hope it helped:)
