Step-by-step explanation:
10x² + 11x − 6 = 0
10x² + 15x – 4x – 6 = 0
5x(2x + 3) – 2(2x + 3) = 0
(2x + 3) (5x – 2)
The speed of a yacht traveling a distance of 1.357 km in 165 minutes is 0.5 km/h
<h3>What is Speed?</h3>
The speed of an object is the distance covered by the object in respect to time.
Mathematically:


- We know that 60 minutes = 1 hour
- 165 minutes = 2.75 hours

Speed = 0.5 km/hour

You need to find the area of the ceiling, floor, the two rectangle walls and the two trapezoid walls
<u>Area of the ceiling:</u>
c = length * width
c = 9*6.5 = 58.5
<u>Area of the 2 rectangle walls:</u>
w = 2(length * width)
w = 2(9 * 8)
w = 2(72)
w = 144
<u>Area of floor:</u>
f = 9 * 7.5
f = 67.5
<u>Area of the two trapezoids:</u>

a = 6.5
b = 7.5
h = 7.5






Total Surface Area = c + w + f + t
Total Surface Area = 58.5 + 144 + 67.5 + 105
Total Surface Area = 375 
The slope-intercept form for the line with slope -5 and y-intercept 3 is,
y= -3x+5.
What is the slope-intercept form of a line?
The conventional form Ax + By = C and y= mx + b have been used to describe linear equations. The slope-intercept form y = mx + b will now be the focus of our attention.
You can write a linear function using the slope of the line and the y-intercept in the slope-intercept form.
y=mx+b
Where b is the y-intercept and m is the slope.
A straight line's slope-intercept equation is written as y=mx+b, where m denotes the slope and b is the y-intercept.
In this case, m=3 and b=5 and y=3x+5 y=3x+5 is the necessary equation.
Hence,The slope-intercept form for the line with slope -5 and y-intercept 3 is,
y= -3x+5.
