I’m pretty sure it’s the second one
HEY THERE !!
As we know that the area of a circle (A)= πr^2
But if we know the diameter then the area is (A)= π/4× D^2 { here D is for diameter}
Here diameter is 10.5 inches.
A => π/4 × (10.5)^2
A => π/4 × 110.25
A => π/4 × 27.5625
A => 86.54625 { because the value of π = 3.14}
So the area of the cirsle whose diameter is 10.5 inches is 86.54625 inches square.
HOPE IT HELPED YOU.
Answer:
Third
Step-by-step explanation:
First would be, simplified, 2x+10=2x-10
Second, simplified, -2x-10=2x-10
Third, simplified, -2x-10=-2x-10
Fourth, simplified, -2x+10=2x-10
So it's third :)
hope this helps :D
Whenever a quadratic equation is in the form
(i.e. the leading terms is 1), you can solve it by looking for two numbers that give 
when summed and 
when multiplied.
So, in your case,
So, we're looking for two numbers 
such that:
you can clearly check that these numbers are 3 and 4.
