Step-by-step explanation:
If a rectangle has an area of x^2+x-20 and a width of x-4, what is the length?
Answers
Answer:
This (x - 5) represents the length of the rectangle.
Step-by-step explanation:
The formula for the area of a rectangle of length L and width W is A = L * W.
Here, the width is x - 4 and the area is x^2 + x - 20. Dividing the width (x - 4) into the area results in an expression for the length:
x - 4 / x^2 + x - 20
Let's use synthetic division here. It's a little faster than long division.
If the divisor in long division is x - 4, we know immediately that the divisor in synthetic division is 4:
4 / 1 1 -20
4 20
--------------------
1 5 0
This synthetic division results in a remainder of 0. This tells us that 4 (or the corresponding (x - 4) is indeed a root of the polynomial x^2 + x - 20, and so *(x - 4) is a factor. From the coefficients 1 and 5 we can construct the other factor: (x - 5). This (x - 5) represents the length of the rectangle.

m= −2 /7
Step-by-step explanation:
Let's solve your equation step-by-step.
6m+1m=−2
Step 1: Simplify both sides of the equation.
6m+1m=−2
6m+m=−2
(6m+m)=−2(Combine Like Terms)
7m=−2
7m=−2
Step 2: Divide both sides by 7.
7m /7 = −2 /7

In order to add the two values together, you must find the least common multiple for the denominators. The denominators are 8 and 4, and the least common multiple of 8 and 4 is 8. Because you have to multiply 4 by 2 to get 8, you must also multiply 3 by 2 to get 6. This will give you 6/8.

ABC is dilated by a factor of to produce A'B'C'.
What is AB, the length of AB after the dilation? What is the measure of <A?
Answers
Answer: The answer is A
Since we are dilating by 1/2 the image must get smaller. Now that we know that you can divide the side lengths by 2 (or multiply by 1/2) to get A'B' equals 17. Angles measures don't change during dilation because it only affects the side lengths, so angle A' is still 28 degrees

Perimeter of ABCD = 56 units
Perimeter of WXYZ = 140 units
Step-by-step explanation:
To find the perimeter of ABCD, find the sum of all sides
18 + 18 + 10 + 10 = 56
To find the side lengths of WXYZ, use the equation: [tex]\frac{image}{pre-image}[/tex]
45/18 = 2.5
You can also cross multiply to find the missing side lengths, but I'll show you this other way...
Multiply the pre-image side lengths by 2.5
18 × 2.5 = 45
10 × 2.5 = 25
45 and 25 of the new side length of WXYZ
To find the perimeter of WXYZ, find the sum of all sides.
45 + 45 + 25 + 25 = 140
WX = 45, XY = 25, YZ = 45, ZW = 25

g(n) = 18 - 4n
Step-by-step explanation:
Given the recursive formula
g(n) = g(n - 1) - 4 with common difference d = - 4 and g(1) = 14
The explicit formula for an arithmetic sequence is
g(n) = g(1) + (n - 1)d , then
g(n) = 14 - 4(n - 1)
= 14 - 4n + 4
= 18 - 4n

. Jumbo bought 5 books, each with a whole-number price.
The mean price of the books was $10. The median price was $8.
The most expensive book cost $15 and the cheapest cost $6.
What are the possible prices for the other books?
Answers
Mean is average. Multiply total books by the mean to find the total cost:
5x 10 = $50 total.
Subtract the highest and lowest prices to find the total of the remaining 3 books.
50 - 15-6 = 29
The median price was 8, this is the middle number, subtract 8 from 29 to get the cost of the last 2 books:
29-8 =21
Now you need a price lower than the median but higher than the lowest cost so that has to be 7
Subtract 7 from 21 to get the cost of the last book 21-7 = 14
The price of the remaining books is $7 and $14
Mr. Gray's quiz was normally distributed with a mean of 25 and a standard deviation of 10. Find z-scores for each of the following data values
a. 40
b. 27
c. 6
Answers
Answer:
a. 1.5
b. 0.2
c -1.9
Step-by-step explanation:
The computation of the z scores of each of the following data values are as follows:
As we know that
z = (data values - mean)÷ standard deviation
Now
a. The z value is
= (40 - 25) ÷ (10)
= 1.5
b. The z value is
= (27 - 25) ÷ 10
= 0.2
c. The z value is
= (6 - 25) ÷ 10
= -1.9
