Answer:
The Answer is: x = 1.444 with repeating 4.
Step-by-step explanation:
212x - 34(2x + 5) = 38
212x - 68x - 170 = 38
212x - 68x = 38 + 170
144x = 208
x = 208/144 = 52/35 or 1.444
Proof:
212(1.444) - 34(2(1.444) + 5) = 38
306.128 - 34(7.888) = 38
306.128 - 268.192 = 37.936 or approximately 38
Hope this helps! Have an Awesome Day!! :-)
Her sister invited 22 guests. What you have to do to solve this problem is subtract 41-19. We have to do this because Rayliegh invited 19 more people than her sister, but invited a total of 41 people herself. So, to figure out how many people her sister invited we have to know that Rayliegh invited 19 more people and we have to subtract that from the total number she invited to get how many people her sister invited: 22 guests. Can you make me brainliest?

Step-by-step explanation:
The volume of a rectanguiar shape like this one is V = L * W * H, where the letters represent Length, Width and Height. Here L is the longest dimension and is 28 - 2x; W is the width and is 22-2x; and finally, x is the height. Thus, the volume of this box must be
V(x) = (28 - 2x)*(22 - 2x)*x
and we want to maximize V(x).
One way of doing that is to graph V(x) and look for any local maximum of the graph. We'd want to determine the value of x for which V(x) is a maximum.
Another way, for those who know some calculus, is to use the first and second derivatives to identify the value of x at which V is at a maximum.
