Answer:
A. 2564 cm^2
Step-by-step explanation:
There are two triangles (Which both are the same) and three different rectangles.
1. Let's solve the area of the triangles first!
Formula: bh(1/2)
10(26)(1/2)
130
2. Now, let's multiply by 2 since there's two of them:
130(2) = 260
3. So, we got 260. Let's find the area of the three rectangles!
Formula: bh
Rectangle A: 28(36) = 1008
Rectangle B: 10(36) = 360
Rectangle C: 26(36) = 936
4. Add the area of the triangles and the rectangles!
260 + 1008 + 360 + 936 = 2564
So the surface area is 2564 cm^2

Answer:
3 gulps
Step-by-step explanation:
In this problem, f(x) = 3. Plug this into the equation:
3 = -3x + 12
Solve for x:
3 - 12 = -3x + 12 - 12
-9 = -3x
-9 / -3 = -3x / -3
3 = x

Answer:
20
Step-by-step explanation:
AB = √(-4)² + (-3)²
AB = √ 16 + 9
AB = √ 25
AB = 5
AD = 4 ; DC = 4 ; BC = 7
Perimeter = 5 + 4 + 4 + 7 = 20 units
Answer:
Decrease by 20%.
Step-by-step explanation:
We have to find the percent of increase or decrease from n to 
.
Now, 
So there is a decrease fro n to .
Now, the percentage of decrease will be given by
= ![[ \frac{\textrm {Original Value - Final Value}}{\textrm {Original Value}}]\times 100 \%](https://tex.z-dn.net/?f=%5B%20%5Cfrac%7B%5Ctextrm%20%7BOriginal%20Value%20-%20Final%20Value%7D%7D%7B%5Ctextrm%20%7BOriginal%20Value%7D%7D%5D%5Ctimes%20100%20%5C%25)
= ![[ \frac{n - 0.8n}{n}]\times 100 \%](https://tex.z-dn.net/?f=%5B%20%5Cfrac%7Bn%20-%200.8n%7D%7Bn%7D%5D%5Ctimes%20100%20%5C%25)
= 20% (Answer)
