Reorder the terms
b × 2 = b - 4
Move variable to the left
2b = b - 4
Collect the like terms
2b - b = -4
b = -4
Answer:
b = -4
Answer:
Step-by-step explanation:
We are given the following in the question:
where r and r are the radius of the circle.
General equation of circle:
where(h,k,j) is the center of the circle and r is the radius of circle.
If the circle is centered at origin, then,
Equation of circle with radius R centered on origin
Inequality to describe the region that consist of all points lying between the sphere of radius r and R but not on the sphere is given by:
Answer: 450 ft squared
Step-by-step explanation:
to find the area of the rectangle- 16 * 18 is 288, and
to find the area of the triangle- 18 * 18 equals 162,
so add 288 and 162 and you have 450.
