Answer:
Equation of line is y=(12/5)x+2
Step-by-step explanation:
The slope of line AB is -5/12. The line passing X is perpendicular to line AB and hence have a slope of 12/5. The slope intercept form is given by y=mx+c.
Now, point X satisfies the equation. Plugging in the slope of the line we end up with
y=(12/5)*x+c, now to find c
-10=(12/5)*(-5)+c, c=2
Equation of line is y=(12/5)x+2
8 + 5i. I just added the expression normally.
The room is 22.4 feet long
7cm=16ft
9.8cm=?ft
7cm 9.8cm
______=______
16ft x ft
Cross multiply
7x=156.8
divide both sides by 7
x=22.4 ft
You only need one of them:
(135 mile²) x (5,280 feet/mile)²
= (135 mile²) x (27,878,400 feet²/mile²)
= (135 x 27,878,400) mile² - feet² / mile²
= 3,763,584,000 feet²
Well I am not good with ratios but I could try. What do you need help with?
