Answer:
(7m-6n)(7m-6n)Step-by-step explanation:
Given the expression 49m²-84mn+36n², this can also be written as;
49m²-84mn+36n²
= 7²m² - 84mn + 6²n²
= (7m)²-2*7m*6n+ (6n)²
= (7m-6n)²
= (7m-6n)(7m-6n)
Hence the expanded form is (7m-6n)(7m-6n)

Somebody help me please....Make it right..
Answer : 4/15
Step-by-step explanation:
Answer:
2/5
Step-by-step explanation:
2/15, 1/5, 4/15, 1/3
Get a common denominator
2/15, 3/15, 4/15, 5/15
We are adding 1/15 each time
The next term would be 6/15 which simplifies to 2/5
A wise man once said, "300 reduced by 3
times my age is 84." What is his age?
A) 72 B) 48
C) 68 D) 61
Answer:
72
Step-by-step explanation:
Let the man's age be x
300 - 3x = 84
300 - 84 = 3x
216 = 3x
x = 216/3
x = 72
Answer:
A
Step-by-step explanation: cuz 300-72x3=84

Answer:
Problem 1: y = 4x + 6
Problem 2: 48 soda bottles per minute
Step-by-step explanation:
Problem 1:
Equation of a line in slope-intercept form is given as y = mx + b.
Wee have to figure out the value of the slope (m) and the value of y-intercept (b). Them to write an equation that represents the line of the graph, we need to input the values of m and b into the equation, y = mx + b.
Thus,
m = hourly fee = $4
b = initial deposit = $6
Substitute m = 4 and b = 6 into y = mx + b
Equation would be:
y = 4x + 6
Problem 2:
What we are simply asked to do is to find the slope of the line, which is the number of soda bottles the machine will produce per minute
Using the two points (3, 144) and (8, 384),
Slope = ∆y/∆x = (384 - 144)/(8 - 3)
Slope = 240/5 = 48
Thus, the machine will make 48 bottles per minute

Answer:
y = -5/2x +4
Step-by-step explanation:
First, make the equation into standard form.
5x + 2y = -10
2y = -5x - 10
y = -2.5x - 5
In order for two lines to be parallel, they must have the same slope. (In y = mx + b, "m" is the slope)
The slope in y = -2.5x - 5 is -2.5, so we need to find an equation with a slope of -2.5 (or -5/2)
In y = -2/5x - 8, the slope is -2/5
In y = 2/5x + 7, the slope is 2/5
In y = 5/2x - 6, the slope is 5/2
In y = -5/2x +4, the slope is -5/2.
Thus, y = -5/2x +4 is the right answer

Which is the solution
Answer:
Step-by-step explanation:
Since this is a test/homework I'll give a hint.
For a linear equation, you have no idea what x and y is, but thats ok! The test itself has already given you 4 options, so you can just input the x/y coordinates, and if they fit, good for you! If they don't, you may need to try again. There are other more complex and faster ways, but they are (a) more complex.
Hope this helps!

The expression |-2-(-3) can be used to find the difference between point A and which other point?
A. Point B
B. Point C
C. Point D
D. Point E
Answer:
C. Point D
Step-by-step explanation:
Distance between two points
Given two points A(x,y) and B(w,z), the distance between them is:
[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]
If both points have the same y-coordinate (y=z), then
[tex]d = |w - x|[/tex]
Point A has coordinates (-2,3). Point D has coordinates (-3,3). The distance between them is
[tex]d = | -2 - (-3) |[/tex]
Thus the correct choice is
C. Point D

BRAINLIST!!! The area of Alex's room is 168 square feet. If his room is a rectangle and one side is 12 feet, how long is the other side.
Write an equation to find the missing length of Alex's room. Let x = missing length in feet
Solve to find the missing length of Alex's room
Answer:
the missing length is 14 feet.
Step-by-step explanation:
a = L × W
168ft² = 12 × W - divide both sides of the equation by 12
- 168 ÷ 12 = 14
168ft² = 12 × 14
