Answer:
A) -2y + 2x >= 7x+y+5
Step-by-step explanation:
I can't remember how to get there by actually doing math, but I used a calculator on a program called Desmos (don't know if you've heard of it?). It's great because they have lots of types of calculators for any kind of math you're doing. I used the graphing calculator for this one. There's also a scientific calculator which I used a lot throughout middle school when we had to do operations with PEMDAS OR GEMS.
To find the graphing calculator for future problems like this, just type in Desmos Graphing Calculator and it should come up.
Hope you find it useful.
Answer:
7x21
Step-by-step explanation:
First, we need to find the length of the pool. Since it is three times as long as it is wide, it is 21 feet long (7 x 3 = 21). That way we can tell that it is 7x21, with a perimeter of 56 feet, and an area of 147 feet squared.
Answer:
B) -7
Step-by-step explanation:
since since since there is more of the negative number then the positive number, the positive number gets canceled out.
If -2i is a root, then 2i is also a root. If √10 is a root, then -√10 is also a root. Convert all four of these roots into factors using the factor theorem (which says that if R is a root, then (x - R) is a factor).
(x + 2i) (x - 2i) (x - √10) (x + √10)
Multiply these factors together. (It's easiest to multiply the conjugate pairs together first.):
x^4 - 6x^2 - 40
