In order to use the elimination method<span>, you have to create variables that have the same coefficient—then you </span>can eliminate<span> them. Multiply the top </span>equation<span> by 5. Next add the </span>equations<span>, and </span>solve<span> for y. Substitute y = 10 into one of the original </span>equations<span> to find x.</span>
Answer:
x=1.94
x = - 1.94
Step-by-step explanation:
8x² + 5 = 35
Subtract 5 from each side
8x² + 5-5 = 35-5
8x² = 30
Divide each side by 8
8x² /8 = 30/8
x² = 15/4
Take the square root of each side
sqrt( x²) = ±sqrt(15/4)
x = ±sqrt(15/4)
x=1.93649
x = - 1.93649
To the nearest hundredth
x=1.94
x = - 1.94

Answer: 
Step-by-step explanation:
Did you mean "small" or did you mean "shortest?"
Let's assume that the shortest side has length 3. This would be opposite the 30 degree angle. We can form and solve an equation of ratios to solve this problem. Since this is a 30-60-90 degree triangle, the perimeter could be 1x + sqrt(3)x + 2x. 1x is the shortest side, so 1x = 3, and x=3.
Then the perimeter, 1x + sqrt(3)x + 2x, would be 3 + 3sqrt(3) + 6,
or
3(sqrt(3)+2).
