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!

Answer:

(12/1.35)^2 ~= 79.012346

(roughly equal to ~=)

Step-by-step explanation:

divide both sides by 1.35

12/1.35 = √x

square both sides to get rid of √

(12/1.35)^2 ~= 79.012346

Evaluate f-2g for f = 3 and g = 27.

lyudmila [28]

If you would like to evaluate f - 2 * g for f = 3 and g = 27, you can do this using the following step:

f - 2 * g = 3 - 2 * 27 = - 51
The correct result would be - 51.

If you would like to evaluate x * 0 + y * 0 for x = 3 and y = 2, you can do this using the following step:

x * 0 + y * 0 = 3 * 0 + 2 * 0 = 0 + 0 = 0
The correct result would be 0.

Let x= 4

f(4)=4^2+2*4

= 16 + 8

= 24
