Answer:
144
Step-by-step explanation:
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u><u> </u>
- Least Common denominator .
<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>
We have ,
> 1/8 , 2/9 , 3/12 .
The denominator of the fractions are ,
> 8 , 9 , 12
The LCM of 8,9,12 will be ,
2 |<u> </u><u>8</u><u> </u><u>,</u><u> </u><u>9</u><u> </u><u>,</u><u> </u><u>1</u><u>2</u><u> </u>
2 <u>| 4 , 9 , 6</u>
2 |<u> </u><u>2</u><u> </u><u>,</u><u> </u><u>9</u><u> </u><u>,</u><u> </u><u>3 </u>
3 |<u> </u><u>2</u><u> </u><u>,</u><u> </u><u>3 </u><u>,</u><u> </u><u>1</u><u> </u>
Therefore , LCM will be ,
> 2⁴ × 3² = 16 × 9 = 144
Answer:
umm......... 14
Step-by-step explanation:
Sorry need the points just guessing!
Let x be the width, length=4x
(4x+x)×2×2=12.5
20x=12.5
x=0.625
Length = 4×0.625=2.5
Area = 2.5×0.625= 1.5625 km square
Answer:
f+g = 11x-8
f*g = 28x^2 - 47x+15
Step-by-step explanation:
f(x) = 4x - 5 and g(x) = 7x -3
(f+g)(x) = 4x - 5 + 7x -3
Combine like terms
= 4x+7x -5-3
= 11x-8
(f * g) (x) = ( 4x - 5) (7x -3)
FOIL
= 4x*7x + 4x(-3) + (-5)(7x) + (-5)(-3)
=28x^2 -12x-35x+15
Combine like terms
=28x^2 - 47x+15
