Answer:
Step-by-step explanation:
85=2x(x^2+3)(2x+5)
85=2x(2x^3+5x^2+6x+15)
85=4x^4+10x^3+12x^2+30x
4x^4+10x^3+12x^2+30x-85=0
2x^2(2x^2+5x+6)+30x-85=0
shoot, this isn't possible with quadratic, maybe you can get somewhere from here
Answer:
B. Not enough information.
Step-by-step explanation:
We are given that all three angles of ∆DEF is congruent to all the three corresponding angles of ∆XYZ. However, this is is not enough to prove that they are both congruent to each other. There's no information about any of tge side length.
AAA is not a criterion that proves two triangles are congruent.
Therefore, we will conclude that there is not enough information.
AA - and - CB - and - DAC .
X is equal to 6 (2*6-3is equal to 9)
Answer
Find out the how many comic books does Jim have.
To proof
Let us assume that comic books Jim have be u.
Let us assume that comic books Charlie have be v .
Let us assume that comic books bob have be w .
As given
jim has three times as many comic books as Charlie
thus
u = 3v
Charlie has two thirds as many books bob.
Thus
bob has 27 books .
i.e w = 27
Put this in the equation
Solving
v = 18
thus
comic books Charlie has be 18 .
Put v = 18 in the u = 3v
u = 3 × 18
= 54
comic books Jim has be 54 .
Hence proved
