Answer:
<h2>h = 12</h2>Step-by-step explanation:
To find the value of h use the formula for finding the slope of a line
That's
Where ( x1, y1) and (x2 ,y2) are the points
From the question
slope = - 3
The points are [4,-9] and [-3,h]
Substitute these values into the equation
We have
Cross multiply
That's
- 3(-7) = h + 9
21 = h + 9
h = 21 - 9
We have the final answer as
<h3>h = 12</h3>Hope this helps you
Answer:
2395 cm²
Step-by-step explanation:
You need to find the area of each side of the prism.
the first side is 3.5x24 which equals 840. there are two of those sides since it's a prism, so multiply by 2. 840x2=1680.
the second side is 13x3.5 which is 45.5. multiply that by 2 for the other side, 45.5x2=91.
repeat for the third side: 24x13=312. 312x2=624.
add all of the sides up to get total surface area. 624+91+1680=2395. :)
