<h2><u>Angles</u></h2><h3>which of these statements properly demonstrates the angle addition postulate for the m<AFC</h3>
<u>Answer:</u>
- <u>Letter D: m∠AFC = m∠AFB + m∠BFC</u>
<u>Explanation:</u>
- Why choice D? When you add the angle ∠AFB and ∠BFC, the answer is ∠AFC. <em>(See picture to make it understandable)</em>

Answer:
Option (B)
Step-by-step explanation:
Let the equation of the exponential function give in the graph is,
f(x) = a(b)ˣ
Since the given graph passes through two points (0, 3) and (-1, 1.5)
For (0, 3),
f(0) = a(b)⁰
3 = a(1) [Since b⁰ = 1]
a = 3
For (-1, 1.5),
f(-1) = a(b)⁻¹
1.5 = 3(b)⁻¹
1.5 =
b =
b = 2
Therefore, equation of the given function will be,
f(x) = 3(2)ˣ
Option (B) will be the answer.
A= Area
l= length
w= width
l= w-3cm
A= l*w
A= 53cm²
53= l*w
(plug in value of length)
53= (w-3)(w)
0=w²-3w+53
Use the quadratic formula:
(in the pictures attached)
w= about 9cm
l=9-3= 6cm
