Answer:
[tex]A=(x+4)^2\text{ or } A=x^2+8x+16[/tex]
Step-by-step explanation:
We have a square garden. One side of the garden has a length of (x + 4).
And we want to write an expression that could represent the area of the garden.
Remember that for a square, all sides have equivalent lengths. So, every side measures (x + 4). The area of a square is given by:
[tex]A=s^2[/tex]
Where s is the length of one side.
Substitute:
[tex]A=(x+4)^2[/tex]
Expand if desired. Hence, the expression for the area is:
[tex]A=x^2+8x+16[/tex]
Martin needs 3.25 gallons of paint for his small barn and 1.25 gallons of paint for his shed. he spends $81 on paint, how much does the paint cost per gallon?
Answer:
$24.92, $65
Step-by-step explanation:
1. $81 divided by 3.25 = 24.9230769231 = $24.92
2. $81 divided by 1.25 = $64.8, rounded could be $65.

Given the functions, fx) = 6x + 2 and g(x) = x - 7, perform the indicated operation. When applicable, state the domain
restriction
(f/g)(x)
Answer:
Step-by-step explanation:
f(x)/g(x)=(6x+2)/(x-7)
The only restriction upon the domain, possible values of x, is division by zero is undefined. So x cannot equal 7.
So the domain is all real numbers except 7. In interval notation the domain is
x=(-oo, 7),(7, +oo)

calculate the perimeter of a quarter circle 2mm use pi=3.14
Answer:
Step-by-step explanation:
If the radius of the circle is 2mm, the circumference is 4π mm.
Arc length of the quarter circle = π mm.
Perimeter of the quarter circle = arc length + 2 radii = 4π + 4 mm = 16.56 mm

1) At a diner, the cost for a specialty waffle and a hashbrown is $9.50. The cost for 2 specialty
waffles and 3 hashbrowns is $20.50. Determine the cost of a waffle and the cost of a hashbrown.
9514 1404 393
Answer:
waffle $8hashbrowns $1.50Step-by-step explanation:
Using w and h for the costs of a waffle and hashbrowns, respectively, we can write the equations for the purchase amounts as ...
w + h = 9.50
2w + 3h = 20.50
Subtracting twice the first equation from the second gives ...
(2w +3h) -2(w +h) = (20.50) -2(9.50)
h = 1.50 . . . . . . simplify
w = 9.50 -h = 8.00 . . . . . find w using the first equation
The cost of a waffle is $8.00; the cost of hashbrowns is $1.50.
Use the equation below to answer the following questions.
a. If you apply the Distributive Property first to solve the equation, what operation will you need to use last?
b. If instead you divide first to solve the equation, what operation would you need to use last?
And use the equation: 6 ( d/3 - 5 ) = 34

Answer the following questions:
2/3 + 3/4 =
Answer:
The answer will be 17/12
Step-by-step explanation:
Hope this Helped
Answer:
1 5/12 or 17/12
Step-by-step explanation:
You can't add them together because they don't have the same denominator so you multiply 2/3 by 4/4 and 3/4 by 3/3. The result is 8/12 and 9/12, you add it together to get 17/12. 17/12 is an improper fraction, if you want you can change it into a mixed fraction which is 1 5/12.
This is kinda easy so you shouldn't make it say college
Which of the following statements could be a correct step in solving this equation:
12x−7=13(x−12)
A. 12x−7=13x−12
B. 3x−42=2(x−12)
C. 3x−7=2(x−12)
D. 3x−7=2x−12
Answer:
A
Step-by-step explanation:
I think the answer is A because you have to use 13 to multiply what's in the bracket in order to collect like terms but 13 *12 won't give you 12. That's the reason why am confused
A quality-assurance worker wants to systematically sample 120 glass jars each day from a conveyor belt in a factory that puts out 3,600 jars each day. If the worker will select every kth jar, what is the best value of k for the worker to use? Enter a whole number.
Answer:
The best value of k for the worker to use is 30.
Step-by-step explanation:
Sample of 120 jars from a set of 3,600.
If the worker will select every kth jar, what is the best value of k for the worker to use?
The best case would be starting at 0 and ending at 3600, finding 120 values, which means that k is given by the division of 3600 by 120. So
[tex]k = \frac{3600}{120} = \frac{360}{12} = 30[/tex]
The best value of k for the worker to use is 30.

Answer:
All those yeye snake me her first
Step-by-step explanation:
Since ∆ABC is congruent to ∆TUV, then:
m<U = m<B
Therefore:
4y - 16 = 3y + 2
Collect like terms
4y - 3y = 16 + 2
y = 18
✔️m<U = 4y - 16
Substitute the value of y:
m<U = 4*18 - 16 = 56°
20 points | If you're good at math, please help me with this 9th grade math, thank you <3 kinda running out of time here
Answer:
y = x^2 + 15x + 56
Step-by-step explanation:
The solutions (where the trinomial = 0) is the factors that will turn the trinomial into 010.
(x + 7)(x + 8) = 0
This means that either -7 will turn the trinomial into 0 or - 8 will.
The trinomial is
x^2 + 8x + 7x + 56 will turn the trinomial to 0.
y = x^2 + 15x + 56 when either - 7 or - 8 is put in for x.
y = (-7)^2 + 15(-7) + 56
y = 49 - 105 + 56
49 + 56 = 105
y = 105 - 105 = 0
y = (-8)^2 - 15(-8) + 56
y = 64 - 120 + 56
y = 120 - 120= 0
No other number will turn the trinomial into 0.

3 * n + 2 = ?
2 * n + 7 = ?
Answer:
1.3n+2
2.2n+7
Step-by-step explanation:
for number 1.you are multiplying 3 and n which gives you 3n but 2 you cant because it dosent have a variable to times with it says plus instead of times.
and for number 2 it the same thing 2 times n equals 2n + 7 is 2n + 7 .
If this doesnt help then im sorry but this is how i know and yeah have a wonderful day.
