Answer:
B. 50.1 -- you are correct
Step-by-step explanation:
The relation in this geometry is ...
BW² = BU·BL
BW = √(33(33+43)) ≈ 50.08
BW ≈ 50.1
3/7 - 2/5 =
15/35 - 14/35 =
1/35 <==
<span>EF = BC = a
ÐF is a right angle.
FD = CA = b
triangle
EF = BC = a
angle F is a right angle.
FD = CA = b
In triangle DEF,
By Pythagoras Theorem,
a2 + b2 = c2
the given
AB=c= a^2 + b^2 square root
Theorefore AB = DE
But by construction, BC = EF
and CA = FD
triangle ABC congruent to DEF (S.S.S)

Answer:
Step-by-step explanation:
31) Y = -3x² + 18 x -25 = -3*x² + -3*-6x -25
= -3(x² -6x) - 25
( (a-b)² =a² - 2ab + b²; here a = x; 2ab = -6x = -2*x*3; and so b = 3)
= -3(x² -6x + 9 - 9) - 25
{ when we add and subtract 9, the equation will not change}
= -3[(x -3)² - 9] -25
= -3(x - 3)² - (-3)*9 - 25
= -3(x - 3)² + 27 -25
= -3(x - 3)² + 2
32) y= -3x² - 18x - 25
= -3 (x² + 6x )-25
= -3 (x² + 6x + 9 - 9) -25
= -3 [ (x+ 3)² - 9] -25
=-3 (x + 3)² - (-3)*9 - 25
= -3(x + 3)² + 27 - 25
= -3(x+3)² +2
