Answer:
16m^2 + 72m + 81
Step-by-step explanation:
you expand it, by (9+4m)(9+4m), using distributive property you get
81 + 36m + 36m + 16m^2, simplifying you get the answer
Answer:
25%
Step-by-step explanation:
George is 33
% (
%) richer than Pete. Let Pete's percentage of wealth be 100%.
Thus George percentage of wealth = 100% +
%
=
%
= 133
%
Pete's percent poorer than George can be determined by;
=
÷
× 100
=
×
×100
= 0.25 × 100
= 25%
Pete is 25% poorer than George.
We need (x-h)^2 + (y-k)^2 = r^2
h = 4, k = 0 and r = 2/3
Take it from here.
Answer:

Step-by-step explanation:
Given equation:

Solving for unknown variable 
Adding 8 both sides by additive property of equality.


Squaring both sides to remove the square root.


Adding 5 both sides by additive property of equality.


Dividing both sides by 6 to isolate 

∴ 
Answer:
-1 < m ≤ - 5
Step-by-step explanation:
Your expression includes: m, -1, -5, >, ≤
m is the value being compared so it will be in the middle.
# sign m sign #
m is no less than -1: no less than means it is greater than -1, but does not include -1. Therefore, our sign is >
m > -1
m is less than or equal to -5. This means we use ≤ because it can equal -5.
m ≤ -5
Now combine the two expressions
m > -1 – This can also be written as -1 < m.
m ≤ -5
-1 < m ≤ - 5
