We can find roots by setting f(x) = 0 --> x^4 - x^3 - 13x^2 + x + 12 = 0.
Factoring f(x) to make things easier for us gives us (x - 1)(x + 1)(x - 4)(x + 3), which, equal to 0, gives us the ability to set each set of parentheses = 0.
x - 1 = 0 gives us x = 1.
x + 1 = 0 --> x = -1.
x - 4 = 0 --> x = 4.
x + 3 = 0 --> x = -3.
our roots are x = 1, -1, 4, and -3.
Answer:
60x
Step-by-step explanation: this would be applying the distributive property
40x+30x-10x
70x-10x
hoped this helped
I took a test yesterday with this question and got it right the answer is 3
A marching band has 1.5 times as many trumpet players as clarinet players.
i.e for every x number of clarinet players , the number of trumpet players= 1.5 x
Now, for every 2 clarinet players players, the number of trumpet players is given by 1.5=3 i’m not sure if it’s the same question but not sure
Angela uses this recipe, but she using twelve times the amount of everything. Therefore, we will do (150g*12=1,800). To turn this to kg, we will divide by 1,000 to get 1.8 kg.
hope this helped!
Answer:
80 cm
