Answer:
189
Step-by-step explanation:
step 1: calculate area of rectangle
Area = l × b
= 10× 15
= 150
step 2: calculate area of half a circle
Area = 1/2 (π.r²)
= 1/2 (22/7 × 5²)
=157/4
step 3: Add the area of rectangle and half a circle together
Area = 157/4 + 150
= 189.26
rounded off to the nearest whole = 189

Answer:
C(x) = 25 + 2x
Step-by-step explanation:
He already has 25 cards.
He is collecting 2 cards per month. In x months, he will have collected:
2 * x = 2x cards
That means that the number of cards he will have after x months will be the sum of the cards he already has and the cards he collects per month:
C(x) = 25 + 2x
