The equation for the perimeter of a rectangle:
P = 2L + 2W
We’re given P and L and asked to find W:
15x + 17y = 2(7/2x + 7y) + 2W
15x + 17y = 7x + 14y + 2W
2W = 8x + 3y
W = 4x + 3/2y
Answer is A.
Answer:
M=5
Step-by-step explanation:
2 ( 2m ) + 4 ( 4m + 2 ) = 108
step 1. do distributive property
4m + 16m + 8 = 108
step 2. add 4m and 16m and subtract 8 from 108
20m = 100
step 3. divide 100 by 20
m = 5
Using the sinusoidal function, it is found that the temperature will be below 0ºC between May and August.
<h3>
What is a Sinusoidal function?</h3>
- A sinusoidal function is a function that depends on a trigonometric function, having peaks according to the period and amplitude given by this function.
The function for the average monthly temperature, in m months after January, is given by:

Working with elementary angles, we have that:





From this, we have that it becomes negative after March, and positive before September, removing the middle two options.
Now, we have to test for April and May, that is, m = 4 and m = 5, hence:


Negative only in May, hence the temperature will be below 0ºC between May and August.

Answer:
37.5 inches
Step-by-step explanation:
Applying the Pythagorean Theorem,
a²+b²=c²
where c is the diagonal length
c=√(25²+28²)= 37.5
