You need to find Circumference of each circle so the top is 7cm and the bottom is 5cm
C = pi • diameter
So top is 3.14 • 7 = 21.98
And bottom is 3.14 • 5 = 15.70
Need any more help?
Answer:
83.80 = 69 + 4x
x = 3.7
Sarah can use up to 3.7 gigabytes per month to stay within her budget
Step-by-step explanation:
83.80 = 69 + 4x
14.8 = 4x
x = 3.7
The equation in the form (x + a)² = b is (x + 2)² = 16
<h3>How to determine the intermediate step?</h3>
The equation is given as:
x² + 4x = 12
Take the coefficient of x
k = 4
Divide by 2
k/2 = 2
Square both sides
(k/2)² = 4
Add this result to both sides of x² + 4x = 12
x² + 4x + 4 = 12 + 4
Evaluate the sum
x² + 4x + 4 = 16
Express as a perfect square
(x + 2)² = 16
Hence, the equation in the form (x + a)² = b is (x + 2)² = 16
