This question is incomplete, the complete question is;

In an interval whose length is z seconds, a body moves (32z + 2z²) ft.

What is the average speed v of the body in this interval?

Answer: the average speed v of the body in this interval is 32 + 2z ft/s

Step-by-step explanation:

Given that;

Length of travel = z seconds

also the body moves (32z + 2z²) ft

i.e

distance travelled = (32z + 2z²) ft

average speed v of the body in this interval = ?

Now to get the Average Speed

we simply say;

Average Speed V =  (32z + 2z²) / z

Average Speed V = 32 + 2z ft/s

Therefore the average speed v of the body in this interval is 32 + 2z ft/s

The formula s= sqrt SA/6
ikadub [295]
For this case we have the following equation:
 s = root (S.A / 6)
 Substituting values we have:
 For S.A = 180:
 s = root (180/6)
 s = root (30)
 For S.A = 120:
 s = root (120/6)
 s = root (20)
 s = root (4 * 5)
 s = 2 * root (5)
 Subtracting both values we have:
 root (30) - 2 * root (5)
 Answer:
 
root (30) - 2 * root (5)

Given the trinomial, what is the value of the coefficient 'B' in the factored form?
Zepler [3.9K]

Answer:

B=9  (I'll solve right now, just so you get the answer)

Step-by-step explanation:

2x^2+14xy-36y^2=2(x+By)(x-2y)

Expand right side by distributing

(2x+2By)(x-2y)

Use the FOIL method to simplify (first, outside, inside, last):

(a+b)(c+d)=ac+ad+bc+bd

(2x*x)+(2x*(-2y))+(2By*x)+(2By*(-2y))\\\\

Simplify

2x^2-4xy+2Byx-4By^2

Re-insert

2x^2+14xy-36y^2=2x^2-4xy+2Byx-4By^2

Cancel out 2x^2

14xy-36y^2=-4xy+2Byx-4By^2

Move all terms to one side

14xy-36y^2+4xy-2Byx+4By^2=0

Simplify

18xy-36y^2-2Byx+By^2=0

Factor out the common term 2

2(9xy-18y^2-Byx+2By^2)

What is 9x-5-8+x= what
Elanso [62]
Hi there!

First you simplify.

Simplified = 9x+(−5)+(−8)+x

Then you combine the like terms.

<span><span><span><span><span>9x</span>+(<span>−5)</span></span>+(<span>−8)</span></span>+x (*-5 and -8 are like terms) (9x and x are like terms)

</span></span><span><span><span>Combined it's~ (<span><span>9x</span>+x</span>)</span>+<span>(<span><span>−5</span>+<span>−8</span></span>)

</span></span></span><span><span><span>Solve and that comes to 10x</span>+<span>−<span>13 which is your answer. :)

Hope this helps.
