12m + 1 - 5m + 4

12m + 5 - 5m

= 7m + 5

Answer:

$7m + 5$

Step-by-step explanation:

If you "open up" the parentheses, you would get:

$12m+1-5m+4$

Which, if you combine like terms, is:

$7m+5$

Hope this helps :)

Cerrena [4.2K]

A number that is less that 7.5 can be used as the lesser of the two consecutive integers with the sum greater than 16, but only if the number used was added with one.

Find a polynomial, which, when added to the polynomial 5x2–3x–9, is equivalent to: x2−5x+6

Bess [88]

The required polynomial is: $-4x^2-2x+15$

Step-by-step explanation:

Let P be the polynomial that has to be found

Given

One polynomial = $5x^2-3x-9$

Sum of both polynomials = $x^2-5x+6$

So,

$(5x^2-3x-9) + P = x^2-5x+6\\P = x^2-5x+6 - (5x^2-3x-9)\\P = x^2-5x+6-5x^2+3x+9\\P = x^2-5x^2-5x+3x+6+9\\P = -4x^2-2x+15$

Hence,

The required polynomial is: $-4x^2-2x+15$
