Hello! Sorry about your luck before although im 99% sure my answer is correct.
Answer: area is 180
Step-by-step explanation:
Ok so first starting off im going to calculate the area for each shape serperately and add them up since thats easier so as demonstrated in the picture the rectangle is 25 because i multiply by base × height and the base and height is 5 and 5 pointed in the picture so thats 25 although i didnt calculate the rest because the base and height is the same for each so we can just do 25 × 6 to get all the rectangles so 25 × 6 = 150 now we got the easy part out of the way now we should do the triangles I pointed to the base and height for that on the left the base being 5 and the height being 3 5 × 3 = 15 BUT WAIT this isn't are area for the triangles because when finding area for triangles we have to divide by 2 so... 15 ÷ 2 = 7.5 since there are 4 of those triangles I dont have to solve for the rest because i can just do 7.5 × 4 so...
7.5 × 4 = 30 now we just combine those areas together! so... 150 + 30 = 180 so 180 is our area HOPE THAT HELPS!
First, I'd simplify this problem by dividing every term by 2:
x^4 - 4x^3 + 5x^2 - 4x + 4 = 0
Then I'd think of the possible factors of that constant term, 4: They would be plus or minus 1, plus or minus 2, or plus or minus 4.
Let's try x = -4 as a possible root. Setting up and using synthetic division:
____________________
-4 / 1 -4 5 -4 4
-4 32
----------------------------
1 -8 37
This result is not helpful. So, try the possible root +4 instead:
________________
+4 / 1 -4 5 -4 4
4 0 20 64
----------------------------
1 0 5 16 68 4 is not a root because the remainder
(68) is not zero.
Try x = 2:
________________
+2 / 1 -4 5 -4 4
2 -4 2 -40
----------------------------
1 -2 1 -2 0
2 is a root because the remainder is zero.
Continue this process until you've found the other 3 roots.
Hint: Try the possible root x = -2 with the following coefficients:
____________
-2 / 1 -2 1 -2

Answer:
350.82
Step-by-step explanation:
To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.
The rectangle's area ():
The triangle's area ():
Now add up all the sides. (3 Rectangles, 2 Triangles.)
The total surface area is 350.82 cm squared.
Here is the answer. I tried to send it vertically but I will send it horizontally again this time. Let me know if it is uncomfortable to see. Feel free to ask me!
Answer:
Step-by-step explanation:
x + y = 180
x = 3y + 8
3y+8 + y = 180
4y = 172
y = 43 degrees
x = 180-43 = 137 degrees
