Hi there!
Since the formula for finding the perimeter of a rectangle is length×2 + width × 2, we can follow this rule.
2 (4x + 5) + 2 (8x - 4)
= 8x + 10 + 16x - 8
= 24x + 2
So, the perimeter is 24x + 2.
Hope this helps!
Correct answer: y=(2/3)x
The line passes through the origin (0,0) and the pair (3,2)
the equation y=(2/3)x satisfies both points:
for (0,0): 0=(2/3)*0 = 0
for (3,2): 2 = (2/3)*3 = 2
and therefore is the correct linear function of the line described.
This is the theoretical probability
A new energy drink advertises 120 calories for 5 oz.
How many calories are in 15 oz?
We can set up a proportion to solve this problem

Where x is the number of calories in 15 oz
Let us solve the above equation for x

Therefore, there are 360 calories in 15 oz of drink.
