The scale factor is 0.25, not 4 in this case. You can determine this by looking at the comparison of the triangles. The first triangle is 4.4 and the second one is 1.1, so the scale factor is determined by looking at what is happening to the first one to result in the second.
0.25 is 1/4. The second hypotenuse is 1/4 the hypotenuse of the first one.
L=7+W
area=30=LW
so subsitute 7+W for length
30=(7+W)(W)
30=W²+7W
minus 30 both sides
0=W²+7W-30
factor
what 2 numbers multiply to get -30 and add to get 7
-3 and 10
0=(W-3)(W+10)
set to zero
0=W-3
3=W
0=W+10
-10=W
false, can't have a negative width
width=3in
L=7+W
L=7+3
L=10
the length is 10in
the width is 3in
let the number be " x "
According to the above statement :
D because those options do not intersect and are part of the universal set
<span>The durations and coverage of the manufacturer’s warranty, as well as whether or not the extended warranty overlaps with it, should be taken into consideration. The likelihood of the item needing repairs, as well as the cost of repairing it, should also be considered. Furthermore, it is helpful to consider the cost of the warranty, its relation to the cost of the item, and whether it is a full or limited warranty.
