4 and 9
Step-by-step explanation:
t2-13t+36=0
factors of 36 are:
1,2,3,4,6,9,12,18,36
factors that add up to 13 are: 9*4
factorise the equation:
(t-9)(t-4)=0
t-9=0 ---> t=9
t-4=0 ---> t=4
Answer:
Step-by-step explanation:
So, if we know that 25 is the area of the square, that means that each side is 5. That also means the diameter of the circle is 5, so the radius is 2.5. Now, we can input the radius into the circumference formula for a circle, which is 2πradius. So, 2π2.5 which equals 5π, or about 15.71
