Answer:
1. Look for factors that each term has in common.
They all have a "b" so factor that out.
a2b + 2ab - 8b = b(a2 + 2a - 8)
2. Factor the remaining polynomial.
Factors of -8 that add to 2 are 4(-2)
a2 + 2a - 8 = (a+4)(a-2)
Final answer: b(a+4)(a-2)

Plans must offer dental coverage for children. Dental benefits for adults are optional. Some of these include drug coverage, pregnancy and childbirth, mental health services, and more. So consider.
By considering your healthcare needs and understanding the various insurance plan options, you can make a more informed choice when shopping for medical and dental insurance. Before you begin shopping for medical and dental insurance, there are a few key things you need to know:
It's important to assess your individual healthcare needs and consider factors such as pre-existing conditions, medication requirements, and anticipated medical/dental procedures. Understanding your healthcare needs will help you choose a plan that provides adequate coverage for your specific situation.
Familiarize yourself with the different types of medical and dental insurance plans available, such as Health Maintenance Organizations (HMOs), Preferred Provider Organizations (PPOs), and dental indemnity plans. Each type of plan has its own benefits, limitations, and costs, so understanding the differences will help you make an informed decision.

19. Ift(x) = 7 - 2x and t(x) = 0, then find x.
20. If h(x) = 4x + 2, then h(x + 3) =
Answer:
see below
Step-by-step explanation:
(x) = 7 - 2x
Let t(x) =0
0 = 7-2x
Subtract 7 from each side
-7 = -2x
Divide by -2
-7/-2 =-2x/-2
7/2 =x
h(x) = 4x + 2
Replace x with x+3
h(x+3) = 4(x+3) + 2
Distribute
= 4x+12 +2
=4x+14
Answer:
19) [tex]x=\frac{7}{2}[/tex]
20) [tex]h(x+3)=4x+14[/tex]
Step-by-step explanation:
19)
We have the function:
[tex]t(x)=7-2x[/tex]
And we want to find x such that t(x)=0.
So, substitute 0 for t(x):
[tex]0=7-2x[/tex]
Solve for x. Subtract 7 from both sides:
[tex]-7=-2x[/tex]
Divide both sides by -2:
[tex]\frac{7}{2}=x[/tex]
Flip:
[tex]x=\frac{7}{2}[/tex]
20)
We have:
[tex]h(x)=4x+2[/tex]
To find h(x+3), substitute (x+3) for x. This yields:
[tex]h(x+3)=4(x+3)+2[/tex]
Multiply:
[tex]h(x+3)=4x+12+2[/tex]
Add:
[tex]h(x+3)=4x+14[/tex]
And we're done!
If x + 2/7x = 9, then x=
Answer: " x = 7 " .
__________________________________________
Step-by-step explanation:
__________________________________________
Given:
x + (2/7)x = 9 ; Solve for "x" ;
Note:
Start by simplifying the "left hand side of the equation:
[tex]x +\frac{2}{7}x =1x +\frac{2}{7}x =[/tex][tex](1\frac{2}{7}) x =\frac{(7*1)+2}{7}x = \frac{(7+2)}{7}x = \frac{9}{7}x[/tex] ;
__________________________________________
Now, rewrite the equation:
__________________________________________
[tex]\frac{9}{7}x =9[/tex] ; Solve for "x" ;
We now multiply each side of the equation by "7" ;
to get rid of the "denominator" within the "fraction value"
on the "left-hand side" of the equation:
[tex]7 *\frac{9}{7}x = 9 * 7[/tex] ;
On the "left-hand side" of the equation:
The "7's" cancel out to "1's" ; since "7÷7 = 1 " ;
And we are left with "9x" on the "left-hand side" of the equation.
On the "right-hand side" on the equation; we find that: "9 * 7 = 63 ."
So; we can rewrite the equation:
9x = 63 ;
To solve for "x" ; we divide each side of the equation by: "9" ;
to isolate "x" on one side of the equation;
& to solve for "x" ;
9x / 9 = 63 / 9 ;
to get:
x = 7 .

Regular exercise can help a person lower their resting heart rate. Suppose an individual’s resting heart rate, in beats per minute, is modeled by the function f(x) = –0.1x 3 + 0.6x 2 + 85 after x weeks of regular exercise.
How many weeks of exercise are necessary to lower the individual’s resting heart rate below 70 beats per minute?
7 weeks
8 weeks
9 weeks
10 weeks
Answer: 9 weeks
Step-by-step explanation:
-0.1³ + 0.6x² + 85 = 70
x ≈ 8.21998224
The answer is 9 weeks because you must round 8.22 up to 9. The reason you round up to 9 is because must include the numbers after the decimal in a week, but you cannot have 0.22 weeks, so 0.22 rounds up to 1.

If the area of a square plot of
land is 9 miles squared, what is
the perimeter of this land?
Answer:
[tex] \huge{ \fbox{ \sf{12 \: miles}}}[/tex]
Step-by-step explanation:
Given,
Area of a square plot = 9 miles
First, finding the length of the land
[tex] \boxed{ \sf{Area \: of \: a \: square \: = \: {length}^{2} }}[/tex]
[tex] \mapsto{ \sf{9 = {length}^{2} }}[/tex]
[tex] \mapsto{ \sf{ {length}^{2} = 9}}[/tex]
[tex] \mapsto{ \sf{ \sqrt{ {(length)}^{2} }} = \sqrt{9} } [/tex]
[tex] \mapsto{ \sf{length = 3 \: miles}}[/tex]
Now , finding the perimeter of the land :
[tex] \boxed{ \sf{perimeter \: of \: a \: square = 4 \: * length}}[/tex]
[tex] \mapsto{ \sf{perimeter \: = \: 4 \: * \: 3}}[/tex]
[tex] \mapsto{ \sf{perimeter \: = 12 \: miles}}[/tex]
The perimeter of the land = 12 miles
Hope I helped!

Answer: (-5,8)
Step-by-step explanation:
If l is a vertical line passing through points A(a, b) and B(c, d), then what can you say about a and c?
Answer:
a and c have the same x value
Step-by-step explanation:
The line is going up, so that means there is a change in the y-values
If the line was horizontal, then there would be a change in the x-values.
Just picture it or draw it out, it would also help
a and c have the same x value
A vertical line is a line, parallel to y-axis and goes straight, up and down, in a coordinate plane. Whereas the horizontal line is parallel to x-axis and goes straight, left and right.
The line is going up, so that means there is a change in the y-values
If the line was horizontal, then there would be a change in the x-values.
