119.7 cm
you find the square root of 14, then multiply it by 8. then you multiply the product of 8(√14) by 4 because there's 4 sides.
Answer:
35.7
Step-by-step explanation:
So to find voulme you would mutiple and we have the two number 11.9 and 3 so you would do 11.9x35.7 this equals 35.7 i hope this helps you.
Answer:

log9(5x^2 + 10) - log9(10) = 1
<=> log9((5x^2 + 10)/10) = log9(9)
<=> (5x^2 + 10)/10 = 9
<=> 5x^2 + 10 = 90
<=> 5x^2 = 80
<=> x^2 = 16
<=> x = +/- (4)
20.
log5(2x^2 + 4) + log5(3) = 2
<=> log5((2x^2 + 4) x 3) = log3(9)
<=> 6x^2 + 12 = 9
<=> 6x^2 = -3
=> No real x satisfies. ( x^2 always larger or equal to 0)
21.
log6(8) + log6(7 - 2x^2) = 2
<=> log6(8 x (7 - 2x^2)) = log6(36)
<=> 56 - 16x^2 = 36
<=> 16x^2 = 20
<=> x^2 = 5/4
<=> x = +/- sqrt(5/4)
Hope this helps!

Answer:
6x+15
Step-by-step explanation:
3×2x + 3×5. use the distributive property of multiplication
I believe that the answer is 1/2 of a minute.
