When you see a coefficient (the number next to the letter) next to a variable (the letter), you multiply. So 3*2=6 So you have: 6+y, or since y=-1, 6+(-)1= 5

3(2) + -1
6-1=5

6-1 is from the 1 being a negative already.

Why does multiplying by 10 shift each digit one place to the left?
Leto [7]

as we move down the list as we push the *digits* to the *left*through the decimal *point* *each* *number has been 10*. and so we can easily *multiply* or divide by *a* power of *10* because of our system of positional numeration. Each Place belongs to the next power of *10*.

Find the zeros of polynomial function and solve polynomials equations.<br> f(x)=24x^3-64x^2-21x+56
8090 [49]

Since this polynomial has 4 terms, factoring by grouping should be the first thing we try here.

So, we have:

8x^2(3x-8)-7(3x-8)=0 \implies\\ (8x^2-7)(3x-8)=0

So, we can use ZPP to find out roots:

3x-8 =0 \implies\\ x=\frac{8}{3}\\ 8x^2-7=0 \implies \\ 8x^2=7 \implies \\ x^2=\frac{7}{8} \implies \\ x=\pm\frac{\sqrt{7}}{\sqrt{{8}}}\\ \text{Rationalizing denominator:}\\ x=\pm\frac{\sqrt{56}}{8}

So our three roots are:

x \in \{\frac{8}{3},\frac{\sqrt{56}}{8},-\frac{\sqrt{56}}{8}\}

A rectangle and regular hexagon are shown below. Find the value of x that makes the polygons above have the same perimeter
pav-90 [236]
The answer is x=3
because 3x2 is 6 and 6x6 is 36 because a hexagon has 6 sides, and 3x3 is 9+3 is 12 and 12+12 is 24 and 3+3 is 6 so 6+6 is 12 and is you add that to 24 then that’s 36 aswell.
