Answer:

x = -1 or

x = -7

Step-by-step explanation:

Given DAB and BCD are similar :

2x^2 + 7 = x^2 - 8x make the left side of equation 0 by exporting all terms to right side

2x^2 - x^2 + 8x + 7 = 0 add like terms

x^2 + 8x + 7 = 0

(x + 1) * (x + 7) = 0 in this case x is either -1 or -7

galina1969 [7]

Answer:

2m wide

Step-by-step explanation:

$a=lw$

$15\frac{1}{2} =7\frac{3}{4} w$

$\frac{31}{2} =\frac{31}{4} w$

$w=\frac{\frac{31}{2} }{\frac{31}{4} } =\frac{(31)(4)}{(31)(2)} =2$

wide = 2m
