We have the quadratic [tex]x^{2} - 6x + 9[/tex] which can factor into [tex]\boxed{(x - 3)(x - 3)}[/tex]
Hope this helps!
Solve for x in the diagram below.
Answer:
x = 20°
Step-by-step explanation:
here's your solution
=> it is given that whole angle is 90°
=> so, x + (3x + 10) = 90°
=> x + 3x + 10 = 90°
=> 4x + 10 = 90°
=>4x = 90 - 10
=> 4x = 80°
=.
=> x = 80/4
=> x = 20°
one angle is 20° and other 70°
hope it helps
Answer:
20 is your answer
x+3x+10=90 being right angle
4x=90-10
x=80/4=20

Andy is wrapping gifts for the holidays. He has 3 rolls of wrapping paper that are 18- inches wide and 24- inches long. What is the total area that 3 rolls of wrapping paper could cover?
Answer:
1296 sq inches
Step-by-step explanation:
To start, you need to get the total area of each individual roll of wrapping paper. To do this, you need to multiply the length x width, which would be 18 x 24 = 432. Then, you have three rolls so you mutiply that by three, which is 432 x 3 = 1296. You add the unit, and that leaves you with 1296 sq inches.
v) Find the perimeter of the rectangle whose length is 60m and breadth is 55m
vi) Find the perimeter of a square room with side equal to 8m each.
Answer:
Step-by-step explanation:
l = length
b = breadth
We know the length is twice the breadth, therefore l = 2b
We also know that the perimeter p = 60m and can also be expressed as a sum of its sides where p = l + l + b + b = 60 which simplified is:
60 = 2l + 2b
Now we have 2 variables, but thankfully we were given a ratio (l = 2b) relating the two. Substituting 2b in for l gives us:
60 = 2(2b) + 2b = 4b + 2b = 6b
60 = 6b
b = 10 m
Now that we know the breadth we can find the length:
l = 2b → l = 2(10) = 20 → l = 20 m
With a breadth of 10 m and a length of 20 m

Tom and Brian are hiking towards each other at the opposite ends of a trail that is 21 miles long. Tom hikes uphill at a speed of 2 miles per hour. Brian is hiking downhill at a speed of 4 miles per hour. How long will it take for the two to meet?
Answer:
3.5 hours
Step-by-step explanation:
Distance = 21 miles
Speed * time
Speed * time = distance
Tom speed = 2 mph
Brian = 4 mph
Let time = t
Brian distance + Tom's distance = total distance
4t + 2t = 21
6t = 21
t = 21 / 6
t = 3.5 hours

find the solution to the system of equations
Answer:
(-3, -4)
Step-by-step explanation:
y= -4
so you plus y in for the y=2x+2 equation where you get x=-3
[tex]\huge\text{Hey there!}[/tex]
[tex]\large\text{If y = -4 then SUBSTITUTE it into the EQUATION}[/tex]
[tex]\large\text{-4 = 2x + 2}[/tex]
[tex]\large\text{TURN the EQUATION}[/tex]
[tex]\large\text{2x + 2 = -4}[/tex]
[tex]\large\text{SUBTRACT by 2 to BOTH SIDES}[/tex]
[tex]\large\text{2x + 2 - 2 = -4 - 2}[/tex]
[tex]\large\text{CANCEL out: 2 - 2 because that gives you 0}[/tex]
[tex]\large\text{Keep: -4 - 2 because it helps us solve for x}[/tex]
[tex]\large\text{2x = -6}[/tex]
[tex]\large\text{DIVIDE by 2 to BOTH SIDES }[/tex]
[tex]\mathsf{\dfrac{2x}{2}=\dfrac{-6}{2}}[/tex]
[tex]\large\text{CANCEL out: }\mathsf{\dfrac{2}{2}}[/tex] [tex]\large\text{because that gives you 1}[/tex]
[tex]\large\text{KEEP: }\mathsf{\dfrac{-6}{2}}[/tex] [tex]\large\text{because it gives us the value of x }[/tex]

How many roots does y=3x^2+8 have?
Answer:
This quadratic has two unequal, imaginary roots.
Step-by-step explanation:
y = 3x^2 + 8 is a quadratic function, and (like all quadratics) it has two roots. In this case they happen to be different (unequal), as well as imaginary.
Setting y = 3x^2 + 8 = 0, we get:
3x^2 = -8, or
x^2 = -8/3
Taking the square root of both sides, we get
x = ±i√(8/3) (2 imaginary roots)
which number is the closest approximate value for sqrt 105
Answer:
10.
Step-by-step explanation:
Lets define a square root. A square root is a number multiplied by itself. 10 x 10 = 100, this is the closest we can get to 105, therefore 10 is the answer.

A jar has marbles in it. Three tenths of the marbles are red. Five tenths of the marbles are blue.
Two tenths of the marbles are green. Which of these fractions is equivalent to four eighths?
The red marbles are 3/10 of the total.
The blue ones are 5/10 of the total.
The green ones are 2/10 of the total.
Of these, 5/10=1/2=(1×4)/(2×4)=4/8
Therefore, five tenths is equivalent to four eighths.
