1. 3(x+2)
3(3+2)
9+6
=15
2. 3x+2
3(3)+2
9+2
=11
3. they are not equivalent expressions because one equals 15 and one equals 11.
Answer:
The two angles are 39°
Step-by-step explanation:
180 - 102 = 78. 78/2 = 39.

The number of infected people will reach 568 in approximately 4 weeks
<h3>Linear equation and function</h3>
Exponential equations are inverse of logarithmic equation and are represented by the equation below:
y = ab^x
where
a is the base value and x is the exponent
Given the equation that shows the number of infected people from an outbreak of the measles as:
y = 4(6)^t
If the number of infected people reach 568, hence;
568 = 4(6)^t
568/4 = 4(6)^t/4
6^t = 568/4
6^t = 142
Take the natural logarithm of both sides
ln(6^t) = ln142
t = ln142/ln6
t = 4.37
Hence the number of infected people will reach 568 in approximately 4 weeks
