Answer:
(2x +3 )(x-5)
one is the length and one is the width
Step-by-step explanation:
2x^2-7x-15
Factor
(2x )(x )
What are the factors of -15? -1*15 and -3*5, 3*-5 , 1*-15
We need 2* one factor ± the other factor = -7
2*-5 +3 = -7
That means the -5 is on the outside and the +3 is on the inside
(2x +3 )(x-5)

PLSSS HELPPPP MEEEEEE I NEED HELP HOENSTLYY I DONT UNDETRSTAND THIS
Step-by-step explanation:
Hey so ok, Ill explain this the best I can.
So you see the 10/2 (10/2 is the fraction just you cant type it in that way)
So 10/2 is litterally 10÷2, which is 5 just imagine that the line inbetween is a division symbol, and it goes from top to bottom, so for example 5/2 would be 5÷2... NOT 2÷5
With this said, to simplify 10/2, just divide the numerator, (Top) by the denominator (bottom) so --> 10÷2 = 5,
so Wednesday would equal 5 (and 5 is the same as 5/1 because 5÷1=5)
Do the same for Thursday 18÷3 = 6
So Thursday would equal 6 (and 6 is the same as 6/1 because 6÷1=6)
and since 6 > 5, (aka 6/1 > 5/1) She ran a longer distance per mile on Thursday, therefore she ran faster on Thursday.
Hopefully I answered your question in the right way.
My little brother needs to know how (8+9)+3 is equivalent to 8+(9+3) and what is the benefit of using that property.

Answer:
Hello Students! Your correct answer is D. Four
Step-by-step explanation:
Use a number line to order the numbers from least to greatest.
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25

Positive nonlinear association
Negative nonlinear association
Answer: A) Positive linear association
Notice how line D is fairly close to all of the points. There are two outliers that aren't really that close to the line, compared to the other points, but for the most part the points are really close to the line. So this suggests that we have linear correlation. The linear correlation is positive due to the fact the regression line has a positive slope. As x goes up, so does y.
Something like line C is only close to the far left point, and the other points are left out. The same goes for lines A and B as well. So I wouldn't consider these lines to be good lines of best fit. The idea is to try to get close to every point as best you can.
What would 6.5 out of ten be as one out of one hundred percentage ?
Answer: 65%
Step-by-step explanation:
First, we will write this as a fraction.
\(\displaystyle \frac{6.5}{10}\)
Next, we will divide the values. When dividing by ten, you can move the decimal place one position to the left.
6.5 / 10 = 0.65
Lastly, we will multiply this value by 100 to write it as a percent.
0.65 * 100 = 65%
Answer:
65%

The work of a student to find the dimensions of a rectangle of area 6 + 8x and width 2 is shown below: Step 1: 6 + 8x Step 2: 2(4) + 2(6x) Step 3: 2(4 + 6x) Step 4: Dimensions of the rectangle are 2 and 4 + 6x In which step did the student first make an error and what is the correct step? (1 point) Question 14 options: 1) Step 3; 2 + (4 + 6x) 2) Step 3; 2 + (4 ⋅ 6x) 3) Step 2; 2(4) + 2(4x) 4) Step 2; 2(3) + 2(4x)
Step-by-step explanation:
Hello,A=IxwStep 1:6+8xStep 2:2(3)+2(4x)Step 3:2(3+4x)Step 4:The dimension of the rectangle are 2 and 3+4x. As a result, Students makes the mistake at Step 2; 2(3)+2(4x). Hope it help!Answer: (4)
Step-by-step explanation:
At step 2 the student rewrites 6 as 2*(4), and 8x as 2*(6x). This is incireect, since 2*(4) is actually 8, and 2*(6x) is 12x.
The correct way to do it is to rewrite 6 as 2*(3), and rewrite 8x as 2*(4x), which corresponds to the answer option (4)
