That is incorrect. The correct answer should be $398.38
First you take 9.2 times 40 and you get $368 which is how much he got paid for the first 40 hours. now he worked 2.25 hours extra so you take 9.2 * 1.5 because he gets 1.5 times more for extra hours. Then you add that to the $368 and you get $398.38
Answer:
it will cost 8.28
Step-by-step explanation:
Answer:
Option B
Option C
Option D
All of these are correct
Step-by-step explanation:
Option B is correct because:
2x + 1 + 2x + 3 = 4x + 4
=> 4x + 4 = 4x + 4
Option C is correct because:
x + 3x + 4 = 4x + 4
=> 4x + 4 = 4x + 4
Option D is correct because:
2(2x + 2) = 4x + 4
=> 4x + 4 = 4x + 4
Option A is incorrect because:
4(x + 4) = 4x + 4
=> 4x + 16 ≠ 4x + 4
8x6= 48 (not necessary to divide by 8 since you'd have to multiply it by 2 anyway because there are 2 triangles)
6x12=72
10x12=120
12x8=96
48+72+120+96=336
336cm^2 is the answer
