Step-by-step explanation:
sqrt(5x)×(sqrt(8x²) - 2×sqrt(x)) =
sqrt(5x × 8x²) - 2×sqrt(5x × x) =
sqrt(40x) × x - 2x × sqrt(5) =
2x×sqrt(10x) - 2x×sqrt(5)
therefore, the last option is correct.
Answer:
The answer is 150, because 300 / 3 = 100, and 100 + 150 = 150.
Answer: 3,6
Step-by-step explanation:
Answer:
108
Step-by-step explanation:
Not the greatest way, but I divide 180 by five (to get how much each 1/5 equals), which is 36. Then I multiply 36 times 3 (which is how many fifths that were used) and you get 108.
Answer:59x-36y
Step-by-step explanation:
-5(4y-7x)+8(3x-2y)
Open the brackets
-20y+35x+24x-16y
Collect like terms
-20y-16y+35x+24x
-36y+59x
Rearrange we get
59x-36y
