Answer:
x=4, x=3
B is correct.
Step-by-step explanation:
Given:
Using middle term splitting factor the left side equation.
Equate each factor to 0 and solve for x
x-4=0 or x-3=0
x=4 and x=3
Hence, The solution of the equation is 4 or 3
Answer:
Diameter of the circle is twice it's radius D=2r.
Circumference of the circle is 2πr.
According to the above problem,
<u>2π(radius)</u>=20 inches
2(radius)=20/π=20/3.14
Diameter=<u>6.37 inches</u>
<h3><u>6.37 inches</u> is the right answer.</h3>
