2 times a number, x, is equal to 6 less than 3 times the number, x.
2x = 3x - 6
-1x = -6
x = 6
The number is 6.
The last set (choice D) is a subset of given set B.
The other 3 choices are wrong.
Answer:
The solutions are given below:
Step-by-step explanation:
x(x-3)+4(x²+2)
= x²-3x+4x²+8
= x²+4x²+8-3x
= 5x²+8-3x
2(a+5)-3(a+7)
= 2a+10-3a-21
= 2a-3a+10-21
= -a-11
xy(x²yz-xy²z+xyz²)
= x³y²z-x²y³z+x²y²z²
-4(a²-2a+8)
= -4a²+8a-32

Answer:
15 inches
Step-by-step explanation:
We have that,
Length of the photo = 4 inches and Width of the photo = 6 inches
Also, the width of the image on the calendar = 10 inches
Let, the length on the image of the calendar = x inches.
Since, the ratio of the photo and its image will remain same, we get,

i.e. 
i.e. x = 15
Hence, the length of the image of the photo on the calendar is 15 inches.
