Answer:
If the question is [tex]2x^{2} -18x+65[/tex] then the answer is no real solution. If the question is 2x - 18x + 65 than the answer is -16x+65
Answer:
x = 13, 5
Step-by-step explanation:
x² - 18x + 65 = 0
step 1: multiply (1) and (65) together
step 2: find two negative numbers to add together to equal -18 but multiply together to equal 65.
step 3: since there isn't a number in front of x² you could:
(x - 13) (x - 5)
x - 13 = 0 x - 5 = 0
+13 +13 +5 +5
x = 13 x = 5
or
(x² - 13x) (-5x + 65)
x(x - 13) -5 (x - 13)
(x - 13) (x - 5)
x - 13 = 0 x - 5 = 0
+13 +13 +5 +5
x = 13, 5

The profit (p) a baker earned, in dollars, is proportional to the number of muffins (m) sold. This equation represents this relationship.
P = 0.75m
enter the profit earned for each muffin sold.
P = 0.75m represents the proportional relationship, therefore, the profit earned for each muffin sold is: $0.75.
What is Proportional Relationship?If two variables, i.e. P and m are directly proportional to each other, the relationship between them can be represented as P = km, where k is the constant.
Given that P = 0.75m represents the proportional relationship between the profit earned and muffins sold, the constant, k, is 0.75, which is the profit earned for each muffin sold.

What is the surface area of this square pyramid?
o 72 cm2
o 384 cm
o 204 cm
o 240 cm2
The surface area of this square pyramid is,
⇒ SA = 296 cm²
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
To find the surface area of this square pyramid
Now, We know that;
the surface area of this square pyramid is,
⇒ SA = B + 1/2 pl
Where, B represents the area of the base. p represents the perimeter of the base. l represents the slant height.
Now, We get;
B = 12 x 8
B = 96
p = 2 (12 + 8)
p = 40
l = 10
Thus, the surface area of this square pyramid is,
⇒ SA = B + 1/2 pl
⇒ SA = 96 + 1/2 x 40 x 10
⇒ SA = 96 + 200
⇒ SA = 296 cm²

how many square feet of outdoor carpet will we need for this hole? 4ft 12ft 8ft 3ft
Answer:
56ft
Step-by-step explanation:
first you need to break the shape u so 1 rectangle and 2 triangles so first we need to find the area of the rectangle
Area of rectangle= w x h so 5* 8= 40
Area of triangle = .5 x b x h so 4 x 4 x .5 = 8 and since we have 2 double that and you get 16 so then you need to add it all up and u get the answer 56

Andrea bough a bucket of colored chalk. The list below shows the fraction of each color of chalk in the bucket. 2/6 are yellow, 5/12 are blue, and 3/12 are green. Andrea told Michelle that less than 1/2 the chalk in the bucket is blue. Michelle said she is mistaken. Who is correct? Explain why you chose your answer.
Given the fraction of each colored chalk, Andrea is right that less than 1/2 the chalk in the bucket is blue.
How to solve fractions?Yellow = 2/6Blue = 5/12Green = 3/12Total = 2/6 + 5/12 + 3/12
= (4+5+3) / 12
= 12/12
= 1
Fraction of blue : Total chalk
= 5/12 : 1
Blue = 5/12 ÷ 1
= 5/12 × 1/1
= 5/12
= 0.42
So,
1/2 = 0.5
Therefore, Andrea is right that less than 1/2 the chalk in the bucket is blue.

2(x -9) = 9 divided ( - 1/3) what value of x makes the equation true
plsss help :)))
Answer:
x = -9/2
Step-by-step explanation:
1. Divide 9 by -1/3:
[tex]\frac{9}{1}[/tex] ÷ [tex]-\frac{1}{3}[/tex] = [tex]\frac{9}{1}[/tex] · [tex]-\frac{3}{1}[/tex]
= -27
2. Divide both sides by 2:
2(x - 9) = -27
[tex]\frac{2(x-9)}{2} = \frac{-27}{2}[/tex]
(x - 9) = [tex]-\frac{27}{2}[/tex]
3. Add 9 to both sides:
x = [tex]-\frac{9}{2}[/tex]

A rectangular rug has side lengths of (x- 2) feet
space does it cover?
and (x + 3) feet. How much floor space does it cover
Hi!
Your answer is [tex]x^2+x+6[/tex]
We are asked to find the floor space it covers, which we can solve for by finding the area of the rectangular rug, given its dimensions.
Dimensions:
(x - 2) x (x + 3)
Area of a rectangle:
Length x Width = Area
Plug dimensions into the formula:
[tex](x - 2)(x +3)[/tex]
