Answer:

\large\boxed{x=2,\ -2}

Step-by-step explanation:

\text{If the trapezoid EFGH is isosceles, then the angles}\ HEF\ \text{and}\ GFE\\\\\text{are congruent. Therefore}\ m\angle HEF=m\angle GFE.\\\\\text{We have the equation}\\\\4x^2+16=5x^2+12\qquad\text{subtract 16 from both sides}\\\\4x^2=5x^2-4\qquad\text{subtract}\ 5x^2\ \text{from both sides}\\\\-x^2=-4\qquad\text{change the signs}\\\\x^2=4\to x=\pm\sqrt4\\\\x=-2\ or\ x=2

What is the lower quartile of the following set? 28, 45, 12, 34, 36, 45, 19, 20 28.5 19.5 19 28
aleksandr82 [10.1K]
To find the lower quartile take the number of terms=n=12
to find the lower quartile take the equation (n+1)/4= 3.25
this means that the lower quartile will be at the 3.25th position int he sequence when all the terms are ordered from smallest to largest. so when ordered: 12  19  19  19.5  20  28  28   28.5   34   36   45   45
so the lower quartile is between 19 and 19.5 exactly 19.125

*LOOK AT PICTURE*<br> A) 8.45 in<br> B) 3.125 in<br> C) 6.25 in<br> D) 62.5 in
RUDIKE [14]
C. 6.25 in

Ratios and cross multiplication:
2 inches is to 130 feet as x is to 406.25 feet

2/130 = x/406.25
(2)(406.25) = (130)(x)
812.50 = 130x
Divide both sides by 130
x = 6.25
