Factor out the greatest common factor for 18x2 + 42x – 12.
Answer:
Step-by-step explanation:
factor the coefficients into primes
18 = 3 * 3 * 2
42 = 3* 2 * 7
- 12 = - 2 * 2 * 3
The primes that are underlined are 2 * 3 which is 6
The primes not in the brackets are what is inside the brackets.

Plot the following co-ordinates and find the fourth point D to make a square A (-1,3) B (1,-1) C(5,1).
Once you have found the missing coordinate use pythagoras to calculate the length of the sides.
Answer:
Step-by-step explanation:
Example: Solve this triangle
right angled triangle 5 12 c
Start with: a2 + b2 = c2
Put in what we know: 52 + 122 = c2
Calculate squares: 25 + 144 = c2
25+144=169: 169 = c2
Swap sides: c2 = 169
Square root of both sides: c = √169
Calculate: c = 13

35 of the apartments have a balcony and 55 of them don't. An apartment is randomly selected as part of a survey. What is the probability it has a balcony?
Answer:
39%
Step-by-step explanation:
It is given that 35 apartments have balconies in them.
While 55 apartments do not have balconies in them.
Total number of balconies is the sum of the apartments. i.e. 35 + 55
= 90 apartments
Therefore for the survey when an apartment is randomly selected, the percentage of the probability of the apartment to have a balcony can be found out by dividing 35 by 90 and then multiply by 100.
i.e.
[tex]$=\frac{35}{90}$[/tex]
= 0.38888888
Multiplying by 100, we get
= 0.388888 x 100
= 38.8888 %
= 39 %
A cell phone is originally priced at $120.The online retailer gives a discount and the cell phone is now priced at $90.enter the percentage discount for the cost of the cell phone.
Answer:
25% off
Step-by-step explanation:
First, find 90/120, which is 0.75. Now, since the phone is not 75% off, you just find 100-75, which gives you 25%.
Joe is buying gift cards that are on sale for 15% off. He uses c – 0.15c to determine the sale price of gift cards. What is an equivalent expression that Joe could also use to determine the sale price of a gift card?
Answer:
0.85c
Step-by-step explanation:
Given :
Discount on sale = 15%
Price of gift card at discounted price = c - 0.15c
Equivalent expression could be :
(100% - 15%) * price
Price = c
(1 - 0.15)c
0.85c

a) find area
a = l • w
a = 17.8 • 10.6
a = 188.68 m²
//
b) find the area of the vegetable garden and then multiply by the cost
a = l • w
a = 49 • 15.2
a = 744.8 m²
total cost = 744.8 • 91
total cost = 67776.8
//
c) find perimeter
p = 2(l) + 2(w)
p = 2(18.7) + 2(12.6)
p = 62.6 m
//
d) find area then divide by 1.25
a = l • w
a = 20 • 15.7
a = 314 m²
314/1.25 = 251.2

A, B, C, D are points on a line, with D the midpoint of segment BC. The
lengths of segment AB is 10; segment AC is 2; and segment BC is 12. What
is the length of segment AD?
Answer:
Also BC = 12
B......6......D......6......C
Now, AC = 2.
A can be either left of C or right of C
If A is left of C , AB = 12-2 = 10 (Correct)
If A is right of C AB = 12 +2 = 14 (Incorrect)
So the points placing is as below
B......6......D....4....A..2..C
Length of segment AD = 4

⇒ 3 √c²
⇒ 3√c × c
⇒ 3c
3) - 5√4x², if x ≥ 0
⇒ - 5 √4x²

⇒ - 5 × 2x
⇒ - 10x
4) - 5√y², if y > 0
⇒ - 5 √y²

A group of 2 adults and 4 children spent $38 on tickets to a museum. A group of 3 adults and 3 children spent $40.50 on tickets to the museum. Based on this information, how much is an adult ticket, and how much is a child ticket?
2a + 4c = 38.00
3a + 3c = 40.50
What values of a and c represent the solution to the system?
a =
c =
Answer:
a=8
c=5.5
Step-by-step explanation:
solve simultaneously:
2a + 4c = 38.00
3a + 3c = 40.50
times the first eq. by 3 and the second by 2
6a + 12c = 114
6a +6c = 81
subtract from one another
6a + 12c = 114
-6a +6c = 81
6c = 33
c=5.5
3a + 3x5.5 = 40.50
3a= 24
a=8
Tasha lists all the multiple of 3 from 3 to99. Tony lists all the multiples of 5 from 5 to100. What is the first number that is on both lists? The second.
Answer:
Multiples of 3 = 3, 9Multiples of 5 = 5, 10Step-by-step explanation:
In a list of 3 to 99, the first multiple of 3 will be none other than 3 itself because when multiplied by 1, you get three.
The second number will be: 3 * 2 = 6
In a list from 5 to 100, the first multiple will be 5 with 5 being a multiple of itself when multiplied by 1.
Second number = 5 * 2 = 10

A person on a moving sidewalk travels 24feet the in 7 seconds. The moving side walk has a length of 180 feet. How long will it take to move from one end to the other?
Given:
A person on a moving sidewalk travels 24 feet the in 7 seconds.
The moving side walk has a length of 180 feet.
To find:
Time taken by the person to move from one end to the other.
Solution:
A person on a moving sidewalk travels 24feet the in 7 seconds.
The speed of the person is
[tex]\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}[/tex]
[tex]\text{Speed}=\dfrac{24}{7}[/tex]
[tex]\text{Speed}=\dfrac{24}{7}[/tex]
The moving side walk has a length of 180 feet.
[tex]\text{Time}=\dfrac{\text{Distance}}{\text{Speed}}[/tex]
[tex]\text{Time}=\dfrac{180}{\dfrac{24}{7}}[/tex]
[tex]\text{Time}=\dfrac{180}{1}\times \dfrac{7}{24}[/tex]
[tex]\text{Time}=52.5[/tex]
Therefore, the time taken by the person to move from one end to the other is 52.5 seconds.

The length of a rectangle is six times its width.
If the perimeter of the rectangle is 84 ft, find its area.
The area of the rectangle is 216 square feet
How to determine the area?Let x represents the length and y represents the width.
So, we have:
x = 6y
So, the perimeter is:
P = 2(x + y)
The perimeter is given as:
P = 84
So, we have:
2(x + y) = 84
Divide by 2
x + y = 42
Substitute x = 6y in x + y = 42
6y + y = 42
Evaluate the sum
7y = 42
Divide by 7
y = 6
Substitute y = 6 in x = 6y
x = 6 * 6
x = 36
The area is calculated as:
Area = xy
So, we have:
Area = 36 * 6
Evaluate
Area = 216
Hence, the area of the rectangle is 216 square feet
