Answer:
Option 2 is correct.
Step-by-step explanation:
Given the expression 5x(x + 3) + 6(x + 3).
We have to factorize the expression completely.
Expression is
5x(x + 3) + 6(x + 3)
Take the factor (x+3) common from both the terms, we get
(x+3)(5x+6)
Hence, option 2 is correct.

Number of students in orchestra = 56
The number of students in band is = 1 3/4 times that are in orchestra
Then
Total number of students in band = (7/4) * 56
= 7 * 14
= 98
So 98 students are there playing in the band. I hope the answer and the procedure is clear to you. In future you can use this procedure to solve similar kind of problems without requiring any help from outside.

1) multiplying the sales tax to the negotiated price (15640*.072 = 1126.08)
2) adding the sales tax to the negotiated price and the registration as well (15640+1126.08+106= 16872.08)
3) subtracting the trade in allowance from the computed value (16872.08 - 2500 = 14372.08)

The equation of a circle is:
( x - h )² + ( y - k )² = radius²
Therefore, in this example,
( x + 4 )² + ( y - 6 )² = 25
25 = radius²
radius = 5
Final answer:
The equation you provided is a standard form equation for a circle. By comparing it to the general circle equation and taking square root of the constant on the right side, we find that the radius of the circle is 5.
Explanation:
The equation of a circle is typically given in the form (x - h)² + (y - k)² = r², where (h, k) is the center of the circle and r is the radius.
- Looking at your given equation: (x + 4)² + (y - 6)² = 25, we can see that this fits the general form.
- The radius r is given by the square root of the number on the right side of the equation. In this case, it equals to √25 which is 5.
Therefore, the radius of the circle is 5.

so we notice that if we solve the second equation (3+y=6), we get a value for y and no value for x so just draw a horizonal line at the point 3 on the y axis
then make the second equation into slope inercept form y=mx+b
x-2y=2
2y-x=-2
2y=x+2
y=1/2x+1
just put in values for x and get y values, then plot points and get line
find where the line inercepts/crosses the first line (3+y=6) and that is the solution
OR
so a the solution is when both equations are true so just assume both are true and solve for x and y
x-2y=2
3+y=6
first of all the second equation is easy
3+y=6
subtract 3 from both sides
y=3
so we subsitute 3 for y in first equation
x-2(3)=2
x-6=2
add 6 to both sides
x=8
y=3
the solution is the point (8,3)
