I don't know if you are asking for a solution using the method of completing the squares.
3x²-2x-5=0
x²-⅔x-5/3=0
x²-⅔x=5/3
x²-⅔x+(-⅓)²=5/3+(-⅓)²
(x-⅓)²=5/3+1/9
(x-⅓)²=16/9
(x-⅓)²=√16/9
x-⅓=±4/3
x=⅓±4/3
x=5/3,-1
Thus (3x-5)(x+1)

There are 156 laptops and desktop computers in a lab. There are 8 more laptops than deskto
computers. What is the total number of desktops in the lab?
Answer:
It would be 70
Step-by-step explanation:
First step: Divide 156 by 2
156 / 2 = 78
Second Step: The half of 156 is 78. Now we have 78 laptops and desktops, and as we know the question says that "there are 8 more laptops than desktops", the next step to follow is to subtract 8 from 78 (Desktops) and add 8 to the 78 (Laptops).
78 - 8 = 70 Desktops
78 + 8 = 86 Laptops

Lata has collected 75 pennies, Lata's father says that if she arranges the pennies in 15 rows, Lata will be able to make a rectangle using all of her pennies. Is her father correct?
Answer:
Yes, Her father is correct.
Step-by-step explanation:
75/15=5 which means that there will be fifteen rows, with five pennies in each row. Since one side has 5 pennies and the other has fifteen, the sides are different and form a rectangle. To check your work, you can do 15*5 which equals 75 the rectangle of pennies should look like this:

Polly's veterinarian told her a dog that weighs w kilograms needs 30w+70 calories each day to stay healthy. Polly's dog, Otis, weighs 22 kilograms. How many calories does Otis need each day to stay healthy?
Answer: 730 calories
Step-by-step explanation:
Since the function is given as: 30w+70 and Polly's dog, Otis, weighs 22 kilograms.
The amount of calories that Otis need each day to stay healthy will be:
= 30w + 70
= 30(22) + 70
= 660 + 70
= 730 calories

150% of what number is 49?
Answer:
32 2/6
Step-by-step explanation:
150% of what number is 49
Can be written as;
1.5x = 49
( To find the percent of a number, one has to move the decimal back two spaces on the percent ( because a percent is out of 100), and then multiply by the number)
Use inverse operations to solve;
1.5x = 49
/1.5 /1.5
x = 32 2/3
An artist is using tiles and boards for a project. A tile has length 1/4 ft and width 1/4 ft. A board has length 1/4 yd and width 1/4 yd. What is the ratio of the length of the tile to the length of the board? What is the ratio of the area of the tile to the area of the board?
Answer:
Ratio of lengths is 1:3
Ratio of areas is 1:9
Step-by-step explanation:
Firstly, we need the units to be same
Mathematically, 1 yard = 3 feet
A length of 1/4 yards = 1/4 * 3 = 3/4 feet
A width of 1/4 yards = 1/4 * 3 = 3/4 feet
The ratio of the length of the tile to the length of the board
that would be;
1/4 : 3/4 = 1: 3
Let’s now work with area
Mathematically, area in both cases is length * width
For the board, we have that;
3/4 * 3/4 = 9/16 square feet
For the tile, we have that;
1/4 * 1/4 = 1/16 square feet
so the ratio of the tile area to the board area will be;
1/16 : 9/16 = 1: 9
