What is the GCF of 14 and 16?
helpppppppppppppppppppp
Answer:
[tex] \frac{x + 2}{x - 2} [/tex]
Step-by-step explanation:
This is much easier to solve actually since both expressions have the same denominator.
To solve it therefore,just sum the numerators
(x²-4x-2)+(8x+6)
x²+4x+4 Now divide by the common denominator
x²+4x+4/x²-4
Factorize both numerator and denominator
(x+2)(x+2)/(x-2)(x+2)
Cancel out common terms
x+2/x-2

What is the slope and y intercept I’m really new to this and need help
Answer:
The y intercept is -1 and the slope is 4/1
Step-by-step explanation:
When you are trying to find the y-intercept, you look at where the line crosses over the y axis. In this case it was at -1.
The slope indicates how many units it is going up/down or left/right. In this case, the distance between each point is up 4, and right 1. so the slope would be 4/1.
I hope this helps :)
As a part of raising funds for an orphanage,you received $120.50 and wanted to split the money into
groups of food items; clothes and story books .
a)If you want the same amount for each group, how much money will you put into each group?
b)Imagine if you want to save same amount of the money for stationary items, then how will you split the money into various groups?Justify
c)If you receive an extra money of $9.50 from people, then how much will be saved for each group?(Include all the groups)
Answer:
a) there are three groups here
total cash = $120.50
each group takes = $120.50 / 3
each group have = $40.17
b) Total no of groups = 4
Total cash = $120.50
each group takes = $120.50 / 4
Each group have = $30.13
c) Total group =4
Total cash = $120.50 + $9.50
=$130
each group have = $130 / 4
=$32.5

Divide 28 bottles of water into two groups so the ratio is 3 to 4. Be sure to show your work.
Answer:
12:16
Step-by-step explanation:
28 split into two groups could be 12 : 16. To check the work, see if 3/4 is equal to 12/16. It is, so this is the accurate ratio, as 12 + 16 = 28 and 12/16 = 3:4.
A Mars rover traveled from point A to point B at a speed of 4 cm/sec. Worsening conditions during the return trip caused the rover to travel at a speed of 2.5 cm/sec, and increased travel time by 15 minutes. What is the distance between point A and point B?
Using the speed - time relation, the distance between point A and B is 6000 cm
Recall :
Distance = speed × time Time = distance / speedLet ; the time taken = t ; distance = d
To trip :
d = 4t ----(1)Fro trip :
t is in seconds ; 15 minutes = (15×60) = 900 secondsd = 2.5(t + 900)
d = 2.5t + 2250 - - - - - (2)
Equating (1) and (2)
4t = 2.5t + 2250
Collect like terms
4t - 2.5t = 2250
1.5t = 2250
t = 2250 / 1.5
t = 1500 seconds
Hence, distance = 4(t) = 4(1500) = 6000 cm
Therefore, the distance between the points is 6000 cm

What is the value of x in the equation 3(2x + 8) = 0? (4 points) Group of answer choices −8 −4 4 8
Answer:
-4
Step-by-step explanation:
Start with 3(2x + 8) = 0.
Distribute the 3 to the 2x and 8 in the parentheses.
That will give you 6x + 24 = 0.
Subtract 24 from both sides, which will get x by itself and leave you with 6x = -24.
Divide both sides by 6 to get x = -4.
That is your answer.
Hope this helped.

Step-by-step explanation:
If a toy rocket is launched vertically upward from ground level with an initial velocity of 120 feet per second, then its height h after t seconds is given by the equation h(t) = -16t2 + 120t. How long will it take the rocket to return to the ground?
A) 7.5 seconds
B) 16 seconds
C) 3.75 seconds
D) 120 seconds
Answer:
A) 7.5 seconds
Step-by-step explanation:
Height of the ground is zero
-16t^2 + 120t = 0
Divide both sides by 16
-t^2 + 7.5t = 0
Factor out t
t(-t + 7.5) = 0
From the zero product rule
t = {0, 7.5}
0 would be time of launch
7.5 is time back to the ground

what is perfect cube
Answer:
The perfect cube is the result of multiplying the same integer three times. Multiplying the number 4 three times, for example, yields 64. As a result, the number 64 is a perfect cube. Perfect cube = number x number x number.
Step-by-step explanation:
Perfect cube numbers can be obtained by multiplying every number thrice by itself. For example, 1 × 1 × 1 = 1 and 2 × 2 × 2 = 8 and so on. The list of perfect cubes from 1 to 10 is as follows: 1, 8, 27, 64, 125, 216, 343, 512, 729, and 1000.
