Answer:

x2-20x+100

Step-by-step explanation:

You have to factor the expression in order to get your answer

Do this by expanding out the expression: (x-10)(x-10) Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.

Multiply x and x to get  , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together:  . Then combine like terms

Answer:

x=148

Linear pairs add up to 180. Take your value of 32 and subtract it from 180 to find out the value of the remaining angle within the linear pair.

180-32=148

Hence, x=148

Hope this helps!

jenny went to the mall with $120 in her wallet.she spent $25.65 on a shirt, $7.98 on a pair of socks, $16.23 on a cd , and $4.58
Effectus [21]
Total money=$120
on shirt=$25.65
on socks=$7.98
on a cd=$16.23
on snack=$4.58
so total money left=total money-total money spent 
=$120-($25.65+$7.98+$16.23+$4.58)
=$120-$54.44
so total money left=$65.56

7x(x+1.8)=0<br> 7x(x+1.8)=0<br> 7x(x+1.8)=0 <br> Answer those 3
ahrayia [7]

Answer:

The answer to all of those questions would be x=-1.8

Step-by-step explanation:

7x(x + 1.8) = 0 - Distribute through the Parenthesis -

7x^2 + 12.6x = 0

x(7x + 12.6) = 0


x = 0


7x + 12.6 = 0

7x = -12.6

x = -12.6/7

x = -1.8


so x = 0 or x = -1.8

What is a polynomial function in standard form with zeroes 1, 2, -2. and -3
Juli2301 [7.4K]
<span>A polynomial with the given zeros can be represented as
   f(x) = (x-1)(x-2)(x+2)(x+3).
   Note that if you set f(x) = 0, then 1,2,-2, and -3 certainly are the solutions. From here, we simply multiply/expand out the polynomial. We can do this in a variety of ways, one of which is taking the left two and right two products separately. We have
   (x-1)(x-2) = x^2 - 3x + 2
   and
   (x+2)(x+3) = x^2 + 5x + 6.
   This gives that
   f(x) = (x^2 - 3x + 2) (x^2 + 5x + 6).
   Expanding this expression out then gives us our answer as
    f(x) = x^4 + 2x^3 - 7x^2 - 8x + 12
   or answer choice B.</span>
