Answer:
Brandon packs 144 days in 36 weeks.
Step-by-step explanation:
Consider the provided information.
It is given that brandon packs lunch 4 days a week.
We need to determine the number of days he pack his lunch for 36 weeks
To find this multiply this number as shown.
4×36 = 144
Now solve this with the help of area model.
The area model is shown in figure
Multiply the number according to area model.
4×36 = (4×30)+(4×6)
= 120 + 24
= 144
Hence, brandon packs 144 days in 36 weeks.

Answer:
A
Step-by-step explanation:
We want to solve the equation:
To do so, we can rewrite the equation.
Recall the double-angle for sine:
By substitution:
Distribute:
We can subtract 3cos(x) from both sides:
And factor:
Hence, our answer is A.
*It is important to note that we should not divide both sides by cos(x) to acquire 10sin(x) = 3. This is because we need to find the values of x, and one or more may result in cos(x) = 0, and we cannot divide by 0. Hence, we should subtract and then factor.
