If sides are congruent then the angles ACROSS from them are also congruent.
Since WV and VU are congruent, angle U is congruent to angle W.
Set up an equation and solve.
See attachment.
x = 8
Angle w = 63

usually, the "r" above, is used as a "rate of increase".
but 1+r combined, can be referred as the "rate for the new size".
so, for example, if something is increasing at a rate of 25%, 1+0.25 or 1.25, the new size wil be 1.25 or 125% of the old size.
Answer:
(x - 3) (x + 4)
Step-by-step explanation:
roots are -4 and 3
then
f = (x + 4)(x - 3)
B. V=9
Multiply it out, then subtract 99 from both sides, then divide by 11
