15x^2 + 41x + 28
STEP BY STEP ANSWER PLSSS
Answer:
(3x+4)(5x+7)
Step-by-step explanation:
15x^2 +41x+28
Factor the expression by grouping. First, the expression needs to be rewritten as 15x^2 +ax+bx+28. To find a and b, set up a system to be solved.
a+b=41
ab=15×28=420
Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 420.
1,420
2,210
3,140
4,105
5,84
6,70
7,60
10,42
12,35
14,30
15,28
20,21
Calculate the sum for each pair.
1+420=421
2+210=212
3+140=143
4+105=109
5+84=89
6+70=76
7+60=67
10+42=52
12+35=47
14+30=44
15+28=43
20+21=41
The solution is the pair that gives sum 41.
a=20
b=21
Rewrite 15x^2 +41x+28 as (15x^2 +20x)+(21x+28).
(15x^2 +20x)+(21x+28)

Approximately 0.02 Love north Atlantic lobsters are born blue color out of 5000 Atlantic lobsters how many would you expect to be in blue color
Answer: 100 blue Atlantic lobsters
Step-by-step explanation:
Approximately 0.02 Atlantic lobsters are born blue.
0.02 in percentages is 2%.
Out of 5,000 Atlantic lobsters therefore, 2% will be born blue.
The number of blue lobsters expected is:
= 5,000 * 2%
= 100 blue Atlantic lobsters

what is 28/10 as a proper fraction
Answer:
Step-by-step explanation:
28/10 as a proper fraction.
28/10 is an improper fraction so you have to turn it into a proper fraction.
To do this divide the numerator (top figure) by 10 (the denominator) which equals 2.8 so to put it as a proper fraction you look at the whole number in 2.8 which is the 2 and keep the number after the decimal point as a fraction over the 10.
The answer would be 2 8/10

Domain is the set of x-values that can be inputted into function f(x)Interval Notation - [a, b] is inclusive, (a, b) is exclusiveStep-by-step explanation:
According to the graph, our x-values span from -3 to 7. Since both are open dot, they are exclusive from the domain:
Interval Notation (-3, 7)
Inequality Notation -3 < x < 7
Can you please solve this
Step-by-step explanation:
To get the x intercepts you need to set y = 0.
So you will get:
[tex]x^{2}[/tex] - 4x - 12 = 0
which can then be put in the form of:
(x - 6) (x + 2) = 0
The x intercepts are: (6,0) and (-2,0).
For the vertex you would need to convert the equation to vertex form.
which is : y = a[tex](x-h)^{2}[/tex] =k
[tex]x^{2}[/tex] - 4x - 12 = y
turn it in to square form:
([tex]x^{2}[/tex] - 4x + 4) - 12 - 4 = y
[tex](x-2)^{2}[/tex] - 16 = y
so the vertex is = (2, -16)
Would it be a

If arcLM = 8x-56 and arcNP = 5x+22, find arcLP.
Answer:
arcLP = 19
Step-by-step explanation:
Given the following
arcLM = 8x-56
arcNP = 5x+22
Required
arcLP
Given that arcLM = arcNP
8x-56 = 5x+22
8x - 5x = 22 + 56
3x = 78
x = 78/3
x = 26
Let assume arcLP = x - 7
arcLP = 26 -7
arcLP = 19

Aubrey worked at the concession stand during a recent sporting event at her high school. During the first hour of the event, she sold 11 orders of nachos and 18 tacos for a total of 64.95 . During the second hour, she sold 6 orders of nachos and tacos 15 for a total of 43.20.
Answer:
cost of nachos = $3.45
Cost of tacos = $1.5
Step-by-step explanation:
Let
x = cost of nachos
y = cost of tacos
11x + 18y = 64.95 (1)
6x + 15y = 43.20 (2)
Multiply (1) by 6 and (2) by 11 to eliminate x
66x + 108y = 389.70
66x + 165y = 475.20
Subtract to eliminate x
165y - 108y = 475.20 - 389.70
57y = 85.50
y = 85.50/57
y = 1.5
Substitute y = 1.5 to find x
11x + 18y = 64.95 (1)
11x + 18(1.5) = 64.95
11x + 27 = 64.95
11x = 64.95 - 27
11x = 37.95
x = 37.95/11
x = 3.45
cost of nachos = $3.45
Cost of tacos = $1.5

Taut learns that when she spends $65.00 on supplies she is able to grow 162.5 pounds of tomatoes. How many dollars is Taut spending per pound of tomatoes grown?
Answer: $0.4 is spent by Taut per pound of tomatoes grown
Step-by-step explanation:
Given : On spending $65.00 , tomatoes grown by Taut = 162.5 pounds
To find : Taut expenditure per pound of tomatoes grown = ?
As it is given that :
162.5 pounds of tomatoes are grown by spending = $65.00
Thus 1 pound of tomatoes are grown by spending = [tex]\frac{65.00}{162.5}\times 1=0.4[/tex]
Thus $0.4 is spent by Taut per pound of tomatoes grown
