I think it’s $1.35 sorry if I’m not correct
Answer:
x^3-8x^2-5x+84
Step-by-step explanation:
The polynomial can be found by expanding (x+3)(x-4)(x-7)=x^3-8x^2-5x+84
Answer:
B is the best answer
The question is illustrated with the attached figure.

Determine XY
To solve for XY, we make use of the tan function, which states that:
tan\theta = \frac{Opposite}{Hypotenuse}tanθ=
Hypotenuse
Opposite
In this case:
tan\ 60= \frac{YZ}{XY}tan 60=
XY
YZ
Substitute 4 for YZ
tan\ 60= \frac{4}{XY}tan 60=
XY
4
Make XY the subject
XY= \frac{4}{tan\ 60}XY=
tan 60
4
tan\ 60 =\sqrt 3tan 60=
3
So, the expression becomes:
XY = \frac{4}{\sqrt 3}XY=

Rationalize:
XY = \frac{4 * \sqrt 3}{\sqrt 3 * \sqrt 3}XY=

XY = \frac{4\sqrt 3}{3}XY=

Answer: D. Dividing
Step-by-step explanation:
When we divide a number ( whether fraction or not ) by a fraction, then we first change the operator to multiplication and reciprocate the second fraction.
Let's take an example:
Suppose we have h division problem in fraction as
Then, our first step would be to change division operator (÷) by multiplication operator (×) and then ×reciprocate the second fraction , so the next step will become , Now cancel out 3 and 2 from both numerator and denominator , we get
i.e.
Hence, the correct option is "D. Dividing".
True. if you add two positive numbers, the sum will always be positive..
