Answer:

The fully factored form is (m - 7)(m + 2)

Step-by-step explanation:

In order to factor the equation (or any quadratic equation with a first coefficient of 1), you need to look for factors of the last number (-14) that add up to the middle number (-5). So, start by listing the factors of -14.

1, -14

-1, 14

2, -7

-2, 7

The two numbers that add up to -5 are 2 and -7. We now use these in parenthesis with the variable.

(m - 7)(m + 2)

Answer:

2 is your answer

Step-by-step explanation:

If h(x)= 5 then 5= 2x +1

so 5 = 2x + 1

-1 -1 on both sides

then 2x = 4

2 2 divide by 2

which x = 2

Do the ratios 13/14 and 1/2 from a proportion

Gnoma [55]

Answer:

<em>No, I believe not</em>

Step-by-step explanation:

If these fractions were to form a proportion among one another, it would be that 13 / 14 should simplify to 1 / 2, but;

13 / 14 ( simplified ) ⇒ 13 / 14

Now there is another way to check if these fractions do form a proportion, by forming the proportion itself, applying cross multiplication to identify if either side is equivalent to one another;

13 / 14 = 1 / 2,

13 * 2 = 14 * 1,

26 ≠ 14,

<em>Answer; Thus these ratios really don't form a proportion among one another</em>
