Asheville had about 20 more inches of rain and it rained for about 40 more days than Wichita
subtract both rainfall and days for Wichita from the same quantities in Asheville
47.71 - 28.61 = 19.1 , about 20 inches
124 - 85 = 39, about 40
both quantities rounded to the nearest 10
y = 7 which you subtract from 2x which means 2 times x so you use all of those as the value of 2 to see what the answer would be after you multiply it by 2
In order to begin we must start off with the formula for the area of a triangle, which is a=1/2b(h) where a is area, b is base, and h is height.
In this scenario, we know that the area is 45cm^2 and the base is 2h+12 (since it is twice it’s height plus twelve). We can plug this into the area equation and then proceed to solve out accordingly.
a=1/2b(h)
45=1/2(2h+12)(h)
90=(2h+12)(h)
90=2h^2 + 12h
0= 2h^2 + 12h - 90
Simplify by dividing the two out.
h^2 + 6h - 45 = 0.
Now plug into the quadratic formula (with a=1, b=6, and c=-45) as shown in the image below.
After plugging the equation in and solving, we come to the idea that h is roughly equal to 4.34. We can now plug this back into the triangle area formula to solve out for b.
a=1/2b(h)
45=1/2(2h + 12)(h)
45=1/2(20.69)(4.34)
45=45.
In conclusion;
The height is ≈ 4.34
The base is ≈ 8.68
Hope this helps :)
Its 4 because 2+2 is 4 and then you're subtracting 2 and then adding 2 again so its 4
Answer: 201 is the correct answer
