the lengths of the sides of a triangle are 2x+1, 3x-2, and 4x-5. what is the perimeter in terms of x
Answers
Answer:
Step-by-step explanation:
2X + 1 + 3X - 2 + 4X - 5 = 180
9X - 6 = 180
9X = 174
9 = 174
ـــــــــــــــــــــ
9 9
X = 19.333
The perimeter of the triangle in terms of x given the three side lengths is 9x - 6.
What is the perimeter?
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees.
The perimeter of a triangle = sum of the side lengths
(2x + 1) + (3x - 2) + (4x - 5) = 9x - 6

an object is moving at a speed of 6 miles per month. express this speed in feet per hour. Don’t have to round anything up
Answers
Answer: 44 feet.
Step-by-step explanation: If the object is moving at a speed of 6 miles per month, that's 6 miles for every 720 hours at the very least. That's 1 mile for every 120 hours. That's 5280 feet for every 120 hours. The object is moving 44 feet every hour.
The speed of the object is 43.39 feet per hour.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 minute = 60 seconds
1 km = 1000 m
We have,
6 miles = 1 month
1 miles = 5280 feet
1 month = 730 hours
Now,
6 miles = 6 x 5280 feet
6 miles = 31680 feet
So,
31680 feet = 730 hours
Divide both sides by 730.
31680/730 feet = 1 hour
43.39 feet = 1 hour
Thus,
Speed is 43.39 feet per hour.

Find the equation of the line. Use exact numbers.
Answers
Answer:
y=-3/2x+3
Step-by-step explanation:
The slope is -3/2x because it's going down 3 and to the right 2.
And it intercepts the y-axis at 3. Thus, 3 is the y-intercept.
Answer:
y = -3/2 x +3
Step-by-step explanation:
We can use the slope intercept form
y = mx+b where m is the slope and b is the y intercept
The y intercept is 3
Now to find the slope
Pick two points on the line
( 0,3) and ( 2,0)
m = ( y2-y1)/(x2-x1)
= ( 0-3)/(2-0)
= -3/2
The equation of the line is
y = -3/2 x +3

you set up the equation by making it equal to zero. so it’s x^2 + x - 12 = 0
then you solve for x
you do this by factoring. you do this by saying what multiplies to -12 and then adds up to 1 since your a times c is -12 and your b is 1

The perimeter of a square courtyard is 144 m. Find the cost of cementing it at the rate of £5 per m². *
Answers
Answer:
the cost is £ 6,480
Step-by-step explanation:
given:
The perimeter of a square courtyard is 144 m
find:
the cost of cementing it at the rate of £5 per m².
Perimeter = 4 Sides
144 = 4 S
S = 144/4
S = 36
Area = S²
A = 36²
A = 1296 m²
cost of cementing the area = 1296 m² x £5 per m² = £ 6,480
therefore,
the cost is £ 6,480
