Answer is A. X= 11
Have a good day
DE=2KL
8x+12=2(10x-9)
8x+12=20x-18
30=12x
x= 1 1/2
8x+12=DE
8(1.5)+12
12+12=DE
24=DE
Therefore, the measurement of DE is 24.
Answer:
no..........................
The volume of each rectangular prism is the product of its dimensions. The total volume is the sum of the volumes of the two rectangular prisms.
(4 ft)·(6 ft)·(3 ft) + (9 ft)·(2 ft)·(16 ft) = 72 ft³ + 288 ft³ = 360 ft³
It would be D.) 36/162
When you multiply 12 by 3, you get 36. You multiply the same number, 3, by 54 to get 162.
This means that the ratio is equivalent.
