Step-by-step explanation:
Pythagoras (for right-angled triangles) :
c² = a² + b²
c being the Hypotenuse, the side opposite of the right angle. and that would be here the diagonal.
c = diagonal = 10 ft
therefore, the width of the rectangle is 10/2 = 5 ft
10² = 5² + b²
100 = 25 + b²
b² = 75
b = length = sqrt(75) = 8.660254038... ft

Answer:
-2
Step-by-step explanation:
f(x) = -x + 2
f(4) = -(4) + 2
f(4) = -2
Answer:
B
Step-by-step explanation
dilation meaning shrink therefore it still similar shape but smaller so it is not congruent.
35.
5/9= 0.555555556
0.55555556*63=35
2/3= 0.6666666667
0.666666667*63= 42
63-35=28
42-28=14
