A) x -y = 4
B) x + y = 30
x = 4 + y So,
B) 4 + y + y =30
2 y = 26
y = 13
x = 17
Triangular prism
length of slanted side:
sqrt(3^2 + 4^2) = 5
SA = 2(1/2)(8)(3) + 8(12) + 2(5)(12) =240
V = (1/2)(8)(3)(12) = 144
cuboid
SA = 2(7x6) + 2(7x5) + 2(6x5) = 214
V = 7x6x5 = 210
angle D = 92°
Step-by-step explanation:
Since the two figures are congruent.
angle D = angle K
20x + 12 = 25x - 8
5x = 20
x = 4
Substituting this value into angle D, we see that
angle D = 20x + 12
= 20(4) + 12
= 92°

Answer:
1
Step-by-step explanation:
f(x)=(x-1)²+1
f(1)=(1-1)²+1
f(1)=0²+1
f(1)=0+1
f(1)=1
