Slope: -2/3
y intercept: -1
Answer:
Perimeter is 4a - 10
Area is a^2 - 5a
Step-by-step explanation:
Two sides of the rectangle are "a" and two sides of the rectangle are "a-5" add all four sides and you get a+a+a-5+a-5 Combine the like terms and you get 4a - 10.
The area is when you multiple the two sides together
A = lw
A - a(a-5) = a^2 - 5a
The circumference of the circle with a radius of 49mm is 308mm
<h3>How to find the circumference of a circle?</h3>
The circumference of the circle is also known as its perimeter. The formula is expressed as:
C = 2pi r
r is the radius = 49mm
pi = 22/7
Substitute
C = 2 * 22/7 * 49
C = 2 * 22 * 7
C = 308mm
Hence the circumference of the circle with a radius of 49mm is 308mm
