3 0

Answer:

10x^2 (x+2) (x+6)

Step-by-step explanation:

assuming you meant 120 not 1120

10x^4+ 80x^3 + 120x^2

factor out 10 x^2

10x^2 (x^2 +8x+12)

what numbers multiply together to get 12 and add together to get 8

2*6 = 12   2+6 = 8

10x^2 (x+2) (x+6)

B and D are the same answer?????

Find the sum of three consecutive odd integers where x is the greatest integer
myrzilka [38]
X + (x − 2) + (x − 4) = ? ;  In which
<span>
x + x </span>− 2 + x − 4 ; 

Combine the "like terms" ; 

  x + x + x = 3x ; 

  − 2 − 4  =  −6 ; 

So we have:  "3x  − 6" as the sum. ;
___________________________
The sum of three consecutive odd integers, in which "x" is the greatest integer;  is:  "3x − 6" .
_____________________________________________
Note:  The three consecutive odd integers, from least to greatest, are:

"(x − 4)" , "(x − 2)" , and "x" .

The sum is:  "(3x  − 6)<span>" .
</span>_____________________________________________
Note:  "(3x  − 6)" factors into:  " 3(x −2)" .

Note that:  " (x − 2) " is the second integer.
______________________________________________
So the sum total, which is:  "(3x  −  6)" ;  is 3 (three) times the value of the second integer; that is, "3 (x − 2)" .

Find g (a + 1 ), if g(x)=5x-3 ​
nordsb [41]

Answer:

g(a+1)=5a+2

Step-by-step explanation:

so (a+1) is the value of x

you can write it like this:

x=a+1

using substitution, we can swap out all 'x's for 'a+1's. like so;

g(a+1)=5(a+1)-3  -- given

        =5a+5-3   --  distribute

        =5a+2      --  simplify!

Hope i helped! have a great day! please mark brainliest!!

If ABCD congruent to QRST, measure of angle A = x – 10º, and measure of angle Q = 2x – 30º, what is the measure of angle A?
belka [17]

Congruent means they are the same,

A and Q are both the first letters, which mean they would also be the same.

Set the two equations equal to each other, solve for x then solve for angle A.


x-10 = 2x-30

Add 30 to each side:

x+20 = 2x

Subtract 1x from each side:

x = 20


Now replace x with 20 in the equation for A


A = 20-10

Angle A = 10 degrees.
