Circumference=2 x pi x radius
radius= diameter/2= 28/2= 14 ft.
c=2 x 3.14 x 14
c= 87.92 ft. or rounded to 88 feet
Answer:
1. x=27
2. x=3
Step-by-step explanation:
<h3>the first one </h3>
let's solve your equation step-by-step.
x−7=20
Step 1: Add 7 to both sides.
x−7+7=20+7
<h3>the second one </h3>
Let's solve your equation step-by-step.
3x+6=12x−21
Step 1: Subtract 12x from both sides.
3x+6−12x=12x−21−12x
−9x+6=−21
Step 2: Subtract 6 from both sides.
−9x+6−6=−21−6
−9x=−27
Step 3: Divide both sides by -9.
−9x/−9=−27/−9

bearing in mind that a diagonal line from the center of a square will give us an isosceles triangle, Check the picture below.
Answer: B
Step-by-step explanation:
There is a hole at x=2, so the numerator and denominator should both have a factor of x-2.
This eliminates everything except for B.
Initial value is differential equation with a specific value given some point of the domain situation. Hope this helps!
