You can simply expand the factorised form out:
y = 14x² - 21x + 10x - 15
y = 14x² -11x -15

Answer:

The trinomial is 14x^{2}-11x - 15

Step-by-step explanation:

We need to find the trinomial which has the factors  (7x + 5)(2x - 3)

To find the trinomial , we need to multiply the factors

(7x + 5)(2x - 3)

multiply term wise,

14x^{2}-21x +10x - 15

14x^{2}-11x - 15

What is the length of AC¯¯¯¯¯
Nutka1998 [239]

Answer: AC=12 cm

Step-by-step explanation:

To  solve this problem you must apply the law of sines, as you can see below:

\frac{a}{sinA}=\frac{b}{sinB}

Where:

a=13

A=85.2°

B=71.6°

Therefore, you must solve for b, then, you obtain that the lenght AC asked in the problem above is:

b={sinB}*\frac{a}{sinA}\\b=\frac{sin(71.6)*13}{sin(85.2)}\\b=12

the ratio of sadia's age to her father's age is 3:6. The sum of their age is 96 .What is sadia's age​
max2010maxim [7]

We have,

a:b=3:6,a+b=96

Introduce variable x such that a=3x,b=6x

The sum a+b=96 is therefore 9x=96\implies x=10.\overline{6}

So,

a=3\cdot10.\overline{6}=\boxed{32} (sadia's age)

b=6\cdot10.\overline{6}=\boxed{64} (father's age)

Hope this helps :)

PLEASE HELP! I NEED ASAP!!!!<br><br> Explain how to construct a perpendicular bisector
Anna007 [38]
So the first step is to have a line segment.
Put your compass on one of the points and extend the compass to be slightly more than half. Just a bit over half.

Mark a small curvy line above your segment and on the bottom at that length. 

Now pick up the compass, don't change the length of extension, and put it on the other point of your segment. 

Mark above and below your segment like before so it can intersect.

draw a line through the two intersections.

I hope I answered your question.
