Answer:
lcm for cuberoot
that is 2*2*2*5*5*5*3*3*3
make pairs of three common numbers and write them as one.
2*5*3=30
ans =30
check 30*30*30=27000
cube
multiply 27000 three times with itself
27000*27000*27000
=19683000000000.0
Since the area of a triangle is in the form
area=0.5(base)(height)
height=base+7
let base=x
area=0.5(x)(7+x)
30=3.5x+0.5x^2
multiply the equation by 2
60=7x+x^2
subtract 60 from both sides
x^2+7x-60=0
(x-5)(x+12)=0
thus x=5 or x=-12 since we are only considering positive answers
x=-12 is rejected
so base=5 and height=5+7=12
Answer:
The Geometric Mean of 4 and 12 is 6.9
Step-by-step explanation:
The sum of a number and 2
x + 2
is twice the number
2x
answer
<span>x + 2 = 2x</span>
<em>X = 2 cm</em>
Volume = Bh= 8×5×1/2×X= 80
X = 80/20 = 4
