A = Lw (Area equal length times width)
A = 48 (the garden's area is 48 ft2)
L = w + 2
We have values for our variables, so let's plug them in:
48 = w(w + 2)
Distribute:
48 = w2 + 2w
Subtract 48 from both sides:
0 = w2 + 2w - 48
AS you can see, we now have a quadratic. From here we need:
m + n = 2 and
m * n = -48
When we break up the quadratic into (w + m)(w + n)
48 is an even number divisible by 3, so it'll be also be divisible by 6:
48 / 6 = 8
8 + (-6) = 2
8 * -6 = -48, so:
0 = (w + 8)(w - 6) →→ 0 = w + 8, or 0 = w - 6
w = -8 or 6
We can't have a negative width, so it cannot be -8, therefore, the width is 6 ft. I'm sure you can find the length from here.

Demetri solved this problem using his calculator.
17×0.25=
His answer was 42.5. Which of the following is a mental check Demetri can use to determine that his answer is not reasonable?
A.
When a number is multiplied by 0.25, the decimal point in the answer should be moved 2 places to the right instead of 1 place to the left.
B.
Multiplying by 0.25 is the same as multiplying by 4, so his answer should be close to 16 multiplied by 4.
C.
Multiplying by 0.25 is the same as dividing by 4, so his answer should be close to 16 divided by 4.
D.
When a number is multiplied by 0.25, the decimal point in the answer should be moved 1 place to the right instead of 1 place to the left.

Larry drives 225 miles in 4.5 hours abd 375 miles in 7.5 hours. Based on Larrys rate which equation will calcuate the distance Larry drives d, in t hours
The rate of distance which is the average speed driven by Larry is; (d1 + d2)/(t1 + t2) = 50 mph
How to Calculate mathematical rates?We are given;
First distance driven by Larry = 225 miles
First time by Larry = 4.5 hours
Second Distance driven by Larry = 375 miles
Second time by Larry = 7.5 hours
Formula for rate of distance which is speed is;
s = d/t
where;
d is distance
t is time
Thus;
Rate = (225 + 375)/(4.5 + 7.5)
Rate = 600/12
Rate = 50 mph

the growth rate of nominal gdp between 1998 9063
and 2018 20501 was
Answer:
The nominal GDP growth rate between 1998 and 2018 was 126.20 percent.
Step-by-step explanation:
Given that in 1998 the country's GDP was $ 9,063 and in 2018 it was $ 20,501, to determine the nominal growth rate of the nation's GDP, the following calculation must be made:
9,063 = 100
20,501 = X
((20,501 x 100) / 9,063) = X
2,050,100 / 9,063 = X
226.20 = X
226.20 - 100 = 126.20
Therefore, the nominal GDP growth rate between 1998 and 2018 was 126.20 percent.

A soccer team must raise at least $660 buy new equipment. To reach this goal, each of the 12 soccer players sells tickets
to a game. Tickets cost $2.75 each. The school athletics fund donates an additional $10 per player. The situation is
modeled by the inequality shown,
12(2.75r + 10) 660
How many tickets must each player sell to raise the money?
A at least 19
B at least 17
C at least 16
D at least 20
Answer:
At least 17
Step-by-step explanation:
12(2.75r+ 10)≥ 660
33r+120≥ 660
33r≥ 540
r≥ 16.36
You can't sell 0.36 of a ticket to they need at least 17

a. no correlation
b. positive correlation; as time passes, the CPI increases.
C.positive correlation as time passes
Answer:
B
Step-by-step explanation:
The meaning in the situation is B; positive correlation; as time passes, the CPI increases.
What does correlation coefficient convey?The correlation coefficient is the degree of association between two quantities in terms of linear relation. The range of correlation coefficient is -1 to 1
If the correlation is -1, then that refers as the one quantity increases, the other quantity decreases , also the correlation is 0, then there is no linear relationship between two variables.
There are two types of Correlation;
Positive Correlation= With Increase in x value, y value also increases, we call it positive correlation.
Negative Correlation= With Increase in x value, if y value decreases, we call it negative correlation.
As we can see from the points plotted on the graph ,with increase in x value , y value decreases.
Hence, positive correlation; as time passes, the CPI increases.

Determine the domain of the following graph:
Hi there! :)
[tex]\large\boxed{[-6, 6]}[/tex]
The domain of a graph consists of its x-values.
In this graph, we can see endpoints at the value x = -6 and x = 6.
Thus, the domain is from x = -6 to 6.
Since we have endpoints, however, we can use closed brackets "[]" to denote the domain in interval notation. Therefore, the domain of this function is:
[-6, 6].

Find the 76th term on the arithmetic sequence
4, 7, 10, 13
Answer:
229
Step-by-step explanation:
1) the difference of the sequence is:
d=7-4=10-7=13-10=3.
2) the common view of the formula of the n term is:
a(n)=a(1)+d*(n-1), where n - required number of the term (it is 76), d- the calculated difference, a(1) - the 1st term of the given sequence.
3) according to the formula above it is possible to substitute n=76, d=3 and 4, then:
a(76)=4+3*(76-1)=4+225=229.
