Write this polynomial in standard form: 8x² - 4x³ + 12 - 5x simplify the polynomial expression: (4x3 + 10x2 − 3x + 15) + (−2x2 + x −2) an expression is shown. (2x−3)+[4x(3x+2)] which polynomial is equivalent to the given expression? 1. 9x−1 2. 14x+5 3. 12x2+2x−1 4. 12x2+10x−3

1.

2.

3.Option 4

Step-by-step explanation:

1.We are given that a polynomial

We have to write the given polynomial in standard form

In order  to  write the polynomial in standard form then we arrange the terms in polynomial according to increasing power of x

It is required standard form of given polynomial .

2.We are given that a polynomial

We have to simplify the polynomial

3.We are given that an expession

We have to find the value of a polynomial which is equivalent to given expression

Hence ,option 4 is true.

c) yes, because of asa or aas

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
