Answer:
Step-by-step explanation:
Factoring will reveal the solution. So we divide the equation by the greatest common factor of the terms and use that factor as the coefficient. In this case the greatest common factor is just x.
2x^2+5x
x(2x+5) so the equation will equal zero when either of those expressions is zero because zero times anything is zero. x=0 and x=-5/2
Answer:
[tex]x = 0, -\frac{5}{2}[/tex]
Step-by-step explanation:
First move all terms to one side of the equation to set them equal to 0
That is already done in your problem
The try to factor, if possible. In your case, factor out x
x(2x + 5) = 0 Now, use the property that says if AB = 0, then A = 0 or B = 0 or both A and B equal 0
So, x = 0 or 2x + 5 = 0
2x = -5
x = [tex]-\frac{5}{2}[/tex]
Always check your results in the original equation to see if they work
[tex]2(0^{2} + 5(0) = 0 + 0 = 0\\[/tex]
and [tex]2(-\frac{5}{2} )^{2} + 5(-\frac{5}{2} )\\ = 2(\frac{25}{4} ) - \frac{25}{2} \\ = \frac{25}{2} - \frac{25}{2} = 0[/tex]
Both results make the equation true, so [tex]x = 0, -\frac{5}{2}[/tex]

9.) Paul makes $300 a day and works 20 days a month, but he is fined $20 every day he is late. How
many days can he be late if he wants to make at least $5,910?
Answer:
3 days
Step-by-step explanation:
20 day x 300 dollar ＝6000 dollars
6000 dollar - 5910 dollar ＝90 dollar
Can be fined 80 dollar because 20 is even number
So,days can be fined:
60 dollar divide 20 dollar ＝3 days

Nancy lives in a state where sales tax is 9%. This means you can find the total cost of an item, including tax, by using the expression c + 0.09c, where c is the pre-tax price of the item.
Use the expression to find the total cost of an item that has a pre-tax price of $84.00.
9514 1404 393
Answer:
$91.56
Step-by-step explanation:
We can simplify Nancy's cost expression to ...
c +0.09c = c(1 +0.09) = 1.09c
The the total cost of the item of interest is ...
(1.09)($84) = $91.56
20 points!!!! Given the regular hexagon, find the measure of each numbered angle.
m21 = 30°, m2 2 = 60°, m 23 = 30°
m2 1 =m22=m3 = 60°
m21 = 60°, m 2 2 = 30°, m 23= 60°
m 21 = 60°, m 22= 30°, m 23 = 30°
Answer:
C, m angle 1 = 60°, m angle 2 = 30°, m angle 3= 60°
Step-by-step explanation:
Each of the 6 triangles in the hexagon are equilateral, meaning that each angle is 60 degrees (180 degrees in a triangle / 3).

1/2 (18t) +2t(9)-12
Answer:
The answer is 27t - 12.
Step-by-step explanation:
1) Remove parentheses.
[tex] \frac{1}{2} \times 18t + 2t \times 9 - 12[/tex]
2) Use this rule: a/b × c/d = ac/bd.
[tex] \frac{1 \times 18t}{2} + 2t \times 9 - 12[/tex]
3) Simplify 1 × 18t to 18t.
[tex] \frac{18t}{2} + 2t \times 9 - 12[/tex]
4) Simplify 18t/2 to 9t.
[tex]9t + 2t \times 9 - 12[/tex]
5) Simplify 2t × 9 to 18t.
[tex]9t + 18t - 12[/tex]
6) Collect like terms.
[tex](9t + 18t) - 12[/tex]
7) Simplify.
[tex]27t - 12[/tex]
Thus, the answer is 27t - 12.
The diagram shows a wedge ABCDEF.
The base of the wedge is a horizontal rectangle measuring 60cm x 40cm
9514 1404 393
Answer:
77.3 cm
Step-by-step explanation:
The distance FA is the diagonal of rectangle ABFE. We know the length AB, so we need to find the length BF. That is found using the trig relation ...
cos(25°) = BC/BF
BF = BC/cos(25°) ≈ (60 cm)/0.906308 ≈ 66.203 cm
Then the diagonal length FA is found using the Pythagorean theorem:
FA = √(AB² +BF²)
FA = √(40² +66.203²) ≈ √5982.79 ≈ 77.349 . . . cm
The diagonal length FA is about 77.3 cm.

4th term 1 : 1/4 = 1/4
5th term 1/4
About 0.6 of all the students in the fifth grade are girls. If the fifth grade has 85 students, how many of the students are girls?
Answer:
51 girls
Step-by-step explanation:
85 represents the total amount of students in 5th grade, including boys and girls.
0.6 or 60% of the 85 students in 5th grade are girls.
0.6 x 85 = 51
Therefore, there are 51 girls out of the 85 students in 5th grade.

Answer:
Which language is this I don't understand
plese help with both of these
Answer:
Step-by-step explanation:
Explicit formula of a G.P. is given by,
[tex]a_n=a(r)^{n-1}[/tex]
Here, [tex]a_n[/tex] = nth term
a = First term
n = number of term
r = common ratio
Given sequence is 3, 6, 12, .......
a = 3
r = [tex]\frac{6}{3}[/tex] = 2
Therefore, explicit formula will be,
[tex]a_n=3(2)^{n-1}[/tex]
Option (3) is the answer.
Parent function → f(x) = 3ˣ
Transformed function → g(x) = [tex]3^{x+5}[/tex]
Since, g(x) = f(x + 5)
Therefore, function 'f' has been shifted 5 units left.
Option (1) is the answer.
