Answer:
4c² + 11cd + 5d
Step-by-step explanation:
(–4c2 + 7cd + 8d) + (–3d + 8c2 + 4cd)
-4c² + 7cd + 8d - 3d + 8c² + 4cd (opening bracket)
8c²-4c²+7cd + 4cd + 8d - 3d
= 4c² + 11cd + 5d
It has to be 30,40,50
Due to Pythagoras Theron it suggests that longer sides is a*2 and b*2 and 30 and 40 square is 2500
2500 square is 50 meaning it makes this statement true
All others are wrong
Answer:
The relationship between these terms may be sums or difference. You call an expression with a single term a monomial, an expression with two terms is a binomial, and an expression with three terms is a trinomial. An expression with more than three terms is named simply by its number of terms. Plz give brainiest

Answer:
Step-by-step explanation:
side of square=10+10+20=40 m
area of square=40×40=1600 m²
area of small square=π10²=100 π m²
area of bigger semi circle=1/2 ×π×20²=200 π m²
reqd. area of shaded region=1600-(100π+200π)=1600-300π m²
≈1600-300×3.14
≈1600-942
≈658 m²
