Answer:

  • \sf x=2

Step-by-step explanation:

\sf 2x+3= x + 1+4

Add numbers

\sf 2x+3=x+5

Subtract 3 from both sides.

\sf 2x+3-3=x+5-3

\sf 2x=x+2

Subtract x from both sides.

\sf 2x-x=x+2-x

\sf x=2

Step-by-step explanation:

x + 1 + 4 = 2x + 3

x + 5 = 2x +3

x + 2 = 2x

2 = x

How many factors does the following term have? <br><br> 2xy
egoroff_w [7]

<u>Answer:</u>

  • 4 factors.

<u>Explanation:</u>

<em>Factors are numbers that if they are divided, then they would be divisible. We can see that the term is multiplied with 3 terms. Hence, they are definitely factors of that term. However, there is one more factor that is divisible by 2xy. The number 1 is divisible by 2xy. Hence, the factors of this term is 2, x, y, and 1.</em>

Hoped this helped.

Answer:

D.648 inches​

Step-by-step explanation:

A yard is a unit that mostly used in America and Canadia to measure the length of something field-size, so it's used a lot in sport. One yard equal to three feet, while one foot equals to 12 inches. There is a higher unit than yard called miles which equals to 1760 yards or 1.60934 kilometers.

Since the measurement is 18 yards, the length in feet will be: 18 yards * 3 feet/yard= 54 feet.

The measurement in inch will be: 54 feet * 12 inches/feet = 648 inches.

Urgent!

Step-by-step explanation:

18.

the last one.

-4.9t² + 24.5t + 117.6 = 0

the ball starts at 117.6 meters height. then, during the first seconds the thrust upwards is adding height, until finally, with more and more seconds passing, gravity will win with a vengeance and pulls the ball down faster and faster than any other force in any other direction.

19.

the general solution for a quadratic equation

y = ax² + bx + c

is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = t

a = -4.9

b = 24.5

c = 117.6

t = (-24.5 ± sqrt(600.25 - -4×4.9×117.6))/-9.8 =

= (-24.5 ± sqrt(600.25 + 2304.96))/-9.8 =

= (-24.5 ± sqrt(2905.21))/-9.8 = (-24.5 ± 53.9)/-9.8

t1 = (-24.5 + 53.9)/-9.8 = -3

t2 = (-24.5 - 53.9)/-9.8 = 8

a negative time does not make any sense, so the real solution is : the ball reached the ground after 8 seconds.

20.

now the equation is

-4.9t² + 24.5t + 117.6 = 49

but this is quickly transformed again into a "= 0" equation :

-4.9t² + 24.5t + 68.6 = 0

t = (-24.5 ± sqrt(600.25 - -4×4.9×68.6))/-9.8 =

= (-24.5 ± sqrt(600.25 + 1344.56))/-9.8 =

= (-24.5 ± sqrt(1944.81))/-9.8 = (-24.5 ± 44.1)/-9.8

t1 = (-24.5 + 44.1)/-9.8 = -2

t2 = (-24.5 - 44.1)/-9.8 = 7

again, negative time does not make sense.

the ball will be at 49 m height after 7 seconds.
