Maybe you thought about this:
m^2+6m-77+5=0 => m^2+6m-72=0 => m^2+ 2*3*m+3^2-3^2-72=0
=> m^2+2*3*x+3^2= (m+3)^2 this is the complete square of the binomial, we will still keep it =>
(m+3)^2 -9 -72=0 => (m+3)^2 - 81 = 0 => (m+3)^2 - 9^2 = 0
Now we got the difference squares, it mean a^2 - b^2 = (a-b) (a+b)
In according to this => (m+3-9) (m+3+9) = 0 =>
(m-6) (m+12)=0 => m-6=0 or m+12=0 => m1=6 or m2= -12 !!!!
Are you satisfied with this solution?

The expression is undefined when x=3 or -3
<h3>
Solution:</h3>
- An expression is undefined when it's divided by 0.
- In order to make the denominator equal 0, we need to subtract 9-9.
- Notice that x is squared.
- So x times itself should equal 9. What number is it?
- That's right, 3.
- So we have
- 9-(3)^2=9-9=0
- There's also another solution: x=-3 (-3•(-3)=9
Hope it helps.
Do comment if you have any query.
Answer:
A is false it said it could be greater than 35 or equal to and 100 x 5 = 500 + 1 = 501 therefore a is false
B is false 6.8 could be possible and it could be a decimal it can't only be a whole number
C is false 6 4/5 is a solution so c is false
D is I'm not sure, I think infinite except for 7 and below so maybe true
E is false because any number greater than 7 that are multiplied to 5 can be as long as its greater than or equal to 35
Ok this is what I think. Id rather wait for more answers to be sure thank you.
A rhombus is mainly defined as: "A parallelogram in which all sides are equal".
This means that, in a rhombus:
1- All sides are equal
2- Each two opposite angle are equal
Based in this:
"<span>A figure has four sides measuring 10 centimeters, and two pair of opposite congruent angles." can be classified as a rhombus.
Hope this helps :)

I don’t know the answer I’m sorry god bless you
