First you want to find 2√5+3√7, which is ≈12.40938989. Then you would square that number and you would get ≈153.9929574 rounding to the nearest number you would get ≈154.
So the answer is ≈154.
Answer:
- x³+3x²-6
Step-by-step explanation:
a - b means
b-a
x²-6-( x³ - 2x²)
Distribute the minus sign
x²-6 - x³ + 2x²
Combine like terms
- x³+3x²-6

Actually Welcome to the Concept of the areas.
Since we know that, radius = diameter /2
here, => d = 2r ,
hence we use the formula as,
A = πr^2 ,
here option d.) is correct.
