Answer:

6x² + 48x + 42

Step-by-step explanation:

2(x + 7) 3(x + 1) ← multiply the integers

= 6(x + 7)(x + 1) ← expand factors using FOIL

= 6(x² + 8x + 7) ← distribute parenthesis by 6

= 6x² + 48x + 42

Answer:

2(x+7) = 2x+14 / 3(x+1) = 3x+3

Step-by-step explanation:

When you see equations with parenthesis, that means you must do distributive property. So, whatever number is outside of the parenthesis, you multiply it by all the number inside of the parenthsis.

Use the frequency table to find the mean number of working TV sets in students' homes. (picture attached)

LenaWriter [7]

The correct option is : 2

Explanation

For finding the mean number of working TV sets, we need to divide the total number of TV sets by the total frequency.

Now for finding the total number of TV sets, first we will multiply each number of TV sets by it's frequency and then sum up all the results.

So, the total number of TV sets

$=(0*1)+(1*8)+(2*9)+(3*4)+(4*3) \\\\ =0+8+18+12+12=50$

and total frequency $=1+8+9+4+3= 25$

Thus, the mean number of working TV sets $= \frac{50}{25}=2$

Solve for the given variable

Ne4ueva [31]

Answer:

Step-by-step explanation:

Well we know the first angle is 90 degrees, which means we have 90 degrees left to work with. Then, the top angle would be 60 degrees, because there is a straight line (which of course has to equal 180), so 180-120 = 60. Now, 90-60=30!

What is the slope of the line that passes through the given points (3 2) and (5 12)

forsale [732]

Slope is calculated using:
slope = (change in y) / (change in x)
slope = (12 - 2) / (5 - 3)
slope = 10/2 = 5
