Answer:
7sqrt(15) - 5sqrt(6)
------------------------------
45
Step-by-step explanation:
7 -sqrt(10)
-----------------------
3 sqrt(5) *sqrt(3)
7 -sqrt(10)
-----------------------
3 sqrt(15)
Multiply the top and bottom by sqrt(15)/ sqrt(15)
7 -sqrt(10) sqrt(15)
----------------------- * ------------
3 sqrt(15) sqrt(15)
(7 -sqrt(10))* sqrt(15)
-----------------------------------
3 *15
Distribute
7sqrt(15) - sqrt(150)
------------------------------
45
sqrt(ab) =sqrt(a) sqrt(b)
150 = 25*6
7sqrt(15) - sqrt(25)sqrt(6)
------------------------------
45
7sqrt(15) - 5sqrt(6)
------------------------------
45
Answer:
b. 4x-8
Step-by-step explanation:
1/2 x(8x-16)
= 1/2(8x) - 1/2 (16)
=4x - 8
Hope this helped
Answer= 8/125 or 0.016
16/1000 can be simplified by dividing both the numerator and denominator by 8
16 2
____=___
1000 125
2/125=0.016
C) r = T + 25.3 because you isolate the r variable
Answer:
The answers are actually-
13 + 2 + 9 = 2 + 13 + 9,
