Answer:
B. 36
Step-by-step explanation:
The equation in question is not well written. Let the equation be;
x²+12x+5 = 0
In order to know what number should be added to both sides of the equation, we will take the square of the half of coefficient of x as shown;
Coefficient of x = 12
Half of 12 = 1/2(12) = 6
Square of 6 = 6² = 36
Hence the required number to add to both sides of the equation by completing the square method is 36
Sammy earns money for college by walking dogs and mowing lawns. She earns $3 for each dog she walks and $25 for each lawn she mows. Which expression can be used to determine the amount of money she earns from walking w dogs and mowing m lawns
Answer:
x = 3w + 25m
Step-by-step explanation:
The number of dogs she walks (w) and the number of lawns that Sammy mows (m) need to be multiplied by the amount of money that Sammy makes from each individual action. Both of these products are then added together to equal the total amount of money that Sammy has earned. All of this can be represented with the following expression where x is the total amount of money earned...
x = 3w + 25m

Carmen enters a painting in an art contest. The contest rules say that all paintings must be rectangular with an area no greater than 3,003.84 cm2 . Carmen's painting is 16 cm wide.
What is the greatest length the painting can have and still have an area within the contest rules?
Answer:
[tex]187.74\:\mathrm{cm}[/tex]
Step-by-step explanation:
The area of a rectangle is given by [tex]l\cdot w[/tex]. Therefore, we can set up the following inequality:
[tex]l\cdot 16 \leq 3,003.84[/tex].
Solving this inequality, we have:
[tex]l \leq 187.74[/tex].
Therefore, the largest length Carmen's painting can be is [tex]\fbox{$187.74\:\mathrm{cm}$}[/tex].

A cylinder has a total surface of 3,41946cm2 and a diametre of 0,66cm. What is its height? Step by step
Answer:
Total surface Area(A) = 2pi*r(r+h)
Diameter D= 2r
r=0.66/2=0.33cm
A=3.41946
3.41946=2*3.143*0.33(0.33+h)
3.41946=2.0744(0.33+h)
3.41946/2.0744=(0.33+h)
1.6484=0.33+h
1.6484-0.33=h
h=1.3184cm
Step-by-step explanation: Total surface area is different from area around the cylinder.

Last month, the average price for half gallon of milk in Kroger was $2.05. Now this month, the average price for half gallon of milk in Kroger was $2.25. Which of the following could be used to calculate the percent of increase, p, in the price for half gallon of milk?
A 0.20/ 2.25 = p100
B 0.20/2.05 = p100
WILL MARK YOU BRAINLIEST
Answer: p=122
Step-by-step explanation:
Answer:
P = 112⁰
see in the picture, MNPQ is a parallelogram
=> M = P
<=> 6x - 2 = 4x + 36
<=> 2x = 38
<=> x = 19
with x = 19 => P = 4.19 + 36 = 112⁰

Simplify the numerical expression (15 - 3) x 2 + 10
Answer:
34
Step-by-step explanation:
Using PEMDAS (parentheses, exponent, multiplication, division, addition, subtraction), we solve what's in the parentheses first, so the expression looks like: 12 x 2 +10.
Then since there aren't any exponents, we solve the multiplication problem in the expression: 24 + 10.
Which just leaves addition, which gives us our answer: 34

Help, please! In the diagram, FH = 1/3AC and 3FG = AB. What additional information is necessary to prove that ΔABC is similar to ΔFGH, using the SSS similarity theorem?
1.
2.
3. BC/GH = 3
4. BC/GH = 1/3
=======================================================
Explanation:
The order of the letters is very important. This is because the order tells us how the angles pair up and that leads to telling us how the sides correspond to one another.
Note with ABC and FGH, the first and last letters are AC and FH respectively. These sides correspond. We're told that FH is 1/3 as long as AC when your teacher wrote FH = (1/3)*AC; we can solve for AC to get AC = 3*FH.
Going back to ABC and FGH, we see that the first two letters of each are AB and FG. This is another pair of corresponding sides. We're told that 3*FG = AB. So AB is three times longer than FG.
So far we can see that
AC = 3*FHAB = 3*FGThe missing information we need is that BC = 3*GH. If we know this, then we can use the SSS similarity theorem to prove the triangles are similar. Note how BC are the two last letters of ABC while GH are the last two letters of FGH.
Starting with BC = 3*GH, we can divide both sides by GH and we get BC/GH = 3.

Answer:
-5
Step-by-step explanation:
we distribute the 3 and 2 on both sides to get:
3x+3=2x-2
we can subtract 3 on both sides to get
3x=2x-5
Now we subtract 2x on both sides to get
x=-5

PLZ I NEED HELP ILL MARK U BRAINLEIEST
can someone pls help me i need to know what is 2x - 1 = 7
Answer:
The solution for x would be 4.
Step-by-step explanation:
2x - 1 = 7
The value of x is unknown, but you do know that you are multiplying 2 by x. So, if you rewrite the equation as 7+1=2x, you know that 8=2x. If you then divide both sides by 2, you're left with 4=x which would mean that the variable x has a solution of 4

2. The sum of two numbers is 51 and the greater number is twice the smaller number. Find the numbers aj set up the variables (2 marks) Let Then represent the first number will represent the second number b) What is the equation that represents the above situation? (2 marks) c) Solve the equation. (2 marks)
Answer:
Larger number = 34
Smaller number = 17
Step-by-step explanation:
Given that:
Sum of numbers = 51
Let,
x be the larger number
y be the smaller number
According to given statement;
x+y=51 Eqn 1
x = 2y Eqn 2
Putting x=2y in Eqn 1
2y+y=51
3y=51
Dividing both sides by 3
[tex]\frac{3y}{3}=\frac{51}{3}\\y=17[/tex]
Putting y=17 in Eqn 2
x=2(17)
x=34
Hence,
Larger number = 34
Smaller number = 17
