The difference between two trinomials is 5x2 + 11x − 16. If one of the trinomials is 3x2 − 2x + 7, then which expression could b

vredina [299]

Answer:

$2x^2+13x-23$

Step-by-step explanation:

The first trinomial is

$3x^2-2x+7$

Let the other trinomial be P.

Then

$P+3x^2-2x+7=5x^2+11x-16$

We make P the subject to obtain,

$P=5x^2-3x^2+11x+2x-16-7$

We simplify to obtain,

$P=2x^2+13x-23$

Hence the other trinomial is $2x^2+13x-23$

Write an expression that says "Nine plus a number times 14"

mr_godi [17]

That could be expressed in two different ways ... because
there are no parentheses in your question.

One way:
Call the number ' N ' .
Nine plus the number is (9 + N)
That much times 14 is 14(9 + N) .

The other way:
Call the number ' N '.
The number times 14 is 14N
Nine plus that is 9 + 14N .

Answer:

$4 \frac{1}{7}$

Step-by-step explanation:

$\frac{36}{7} - \frac{ 3}{5} - \frac{4}{10} \\ \\ lcm \: \: is \: \: 70 \\ \\ \frac{360 - 42 - 28}{70} \\ = \frac{290}{70} \\ = \frac{29}{7} \\ = 4 \frac{1}{7}$
