Which is a solution to the equation?(x - 3)(x - 5) = 35
x= -8
x=-5
x=2
x = 10
Answers
(x-3)(x-5)=35
Multiply the brackets together
x*x-5*x-3*x-3*5
x^2-8x+15=35
Move +35 to the other side. Sign changes from +35 to -35
x^2-8x+15-35=35-35
x^2-8x-20=0
(x-10)(x+2)=0
x-10=0 x+2=0
Move -10 to the other side. Sign changes from -10 to +10
x-10+10=0+10 x+2-2=0-2
x=10 x=-2
Answer: x=10
Just plug in the different numbers to see which ones equal 35.
I’m going to plug in x = -8 into the equation
(x - 3)(x - 5) = 35
(-8 - 3)(-8 - 5) = 35 (substitute -8 for x)
(-11)(-13) = 35
143 = 35
This answer is wrong because 143 does not equal 35
Now let’s plug in x = 10
(x - 3)(x - 5) = 35
(10 - 3)(10 - 5) = 35 (substitute 10 for x)
(7)(5) = 35
35 = 35
This solution works because 35 equals 35

The center of the data in the dot plot is B. 3.5.
What are mean, median, and mode?
The three main methods for identifying the average value of a set of integers are mean, median, and mode.
Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.
The middle value in a list that is arranged from smallest to greatest is called the median.
The value that appears the most frequently on the list is the mode.
The mean of the dot plot is (3 + 2 + 5 + 4 + 1 + 6)/6.
mean = 21/6.
mean = 3.5.
As the number of data is even the median is half of the two middle terms.
median = (5 + 4)/2 = 4.5.

To find the perimeter of anything, you look at it and figure out how far
an ant has to walk if you put it down at one corner, and it walks all the way
around all the edges until it gets back to where it started.
On this square with a bite cut out of it, I see three x's and three 1's that
the ant has to walk. That looks a lot like 3x+3 to me.
