Answer:
4.69
Step-by-step explanation:
If this is a perfect square trinomial, you want to look at your constant--36. the square root of 36 is 6, so your factors would be:
(x + 6)(x + 6) ... foil this, and see what your middle value is.
x² + 12x + 36 is your result. 12 is your middle term.
The answer would be B, since the other two just have to equal 100.
Answer:
x=17
Step-by-step explanation:
Since the triangles are congruent, the angles are equal
I≅ P
3x+4 = 72-x
Add x to each side
3x+4+x = 72-x+x
4x+4 = 72
Subtract 4 from each side
4x+4-4 = 72-4
4x= 68
Divide by 4
4x/4 = 68/4
x = 17
The constant is 5 because it is not being effected by the variable it is just a 5
