2x^4 + 8x^3 - 15x^2 + 14x - 3
i think this is the answer. hope this helpss
Answer:
3 / 4
Step-by-step explanation:
We can realize that both the numerator and denominator have a common factor of 9. We can divide them both by 9 to get:
3 / 4
This fraction is in simplest form.
Answer:
Step-by-step explanation:
Rewrite this quadratic equation in standard form: 2n^2 + 3n + 54 = 0. Identify the coefficients of the n terms: they are 2, 3, 54.
Find the discriminant b^2 - 4ac: It is 3^2 - 4(2)(54), or -423. The negative sign tells us that this quadratic has two unequal, complex roots, which are:
-(3) ± i√423 -3 ± i√423
n = ------------------- = ------------------
2(2) 4
You do the sum(40) subtracted by 8, the answer from that divided by 2 since Erin's two times younger.
40-8=32
32÷2=16
Then if you want to check it you do the opposite and get the same sum(40) so 16×2=32 and 32+8=40
Answer:
c and d are the correct answers
