Answer:
All real numbers
Step-by-step explanation:
3(5x - 4) < 15x
~Distribute left side
15x - 12 < 15x
~Subtract 15x to both sides
-12 < 0
Best of Luck!

Answer:
(a) 6² +3² +1² +1² = 47
(b) 5² +4² +2² +1² +1² = 47
(c) 3³ +4² +2² = 47
Step-by-step explanation:
It can work reasonably well to start with the largest square less than the target number, repeating that approach for the remaining differences. When more squares than necessary are asked for, then the first square chosen may need to be the square of a number 1 less than the largest possible.
The approach where a cube is required can work the same way.
(a) floor(√47) = 6; floor(√(47 -6^2)) = 3; floor(√(47 -45)) = 1; floor(√(47-46)) = 1
__
(b) floor(√47 -1) = 5; floor(√(47-25)) = 4; ...
__
(c) floor(∛47) = 3; floor(√(47 -27)) = 4; floor(√(47 -43)) = 2

Step-by-step explanation:
X² <span>+ 11x = -28
to find the solution of this polynomial, it'll be easiest to try and factor it. the first thing you need to do is move everything to one side:
</span>x² + 11x = -28 ... add 28
x² + 11x + 28 = 0 ... factor
(x + 7)(x + 4) = 0 ... now set both of your factors equal to zero and solve for x
x + 7 = 0
x = -7
x + 4 = 0
x = -4
