Mathematics
1 answer:
Hunter-Best [27]2 years ago
4 0

Answer:

  16x² +48x +36

Step-by-step explanation:

A perfect square trinomial is of the form ...

  (a +b)² = a² +2ab +b²

We want to match this form.

__

<h3>comparing terms</h3>

Comparing the known terms, we see ...

  16x² = a²   ⇒   a = 4x

  36 = b²   ⇒   b = 6

<h3>filling in the missing term</h3>

The missing term is the linear term:

  2ab = 2(4x)(6) = 48x

  ? = 48

If &lt;PQR is vertical to &lt;RQS and M&lt;RQS=36 degrees,what is the measure of &lt;PQR?
Firdavs [7]
Ahemm ahemmm, *clearing throat*,  vertical angles are just angles across from each other from a vertex point, so at the junction one is on one side and the other across the junction, and therefore equal.
 
Because the same segments is making them both, with the same opening.

Given the following formula, solve for t. v=u+at
sergeinik [125]

Answer:

<h2>t = \frac{v - u}{a}</h2>

Step-by-step explanation:

v = u + at

To solve for t move u to the left side of the equation

That's

at = v - u

Divide both sides by a in order to make t stand alone

We have

<h3>\frac{at}{a}  =  \frac{v - u}{a}</h3>

We have the final answer as

<h3>t = \frac{v - u}{a}</h3>

Hope this helps and

What two numbers multiply together to get -42 and add up to be -1?
kobusy [5.1K]

Answer:

-7 and 6

Step-by-step explanation:

You can solve this problem by setting up a system of equations. Lets call the first number x, and the second number y. Now:

x*y=-42

x+y=-1

You can subtract y from both sides of the second equation to get x=-y-1, which you can then substitute into the first:

(-y-1)*y=-42

-y^2-y=-42

y^2+y-42=0

Solving the quadratic equation:

(y-6)(y+7)=0

y=-7 or 6

x= 6 or -7

When one of the numbers is -7, the other is 6, and when it is 6, the other is -7. Hope this helps!
