Answer: 2
Step-by-step explanation:
3•(-1)^3 - (-1)^3 + 5•(-1)^3 - 9•(-1)^3
3•(-1) - (-1) + 5•(-1) - 9•(-1)
-3 +1 -5 +9= 2
Y = 8x + 12
if x = -6
y = 8(-6) + 12
y = -48 + 12
y = - 36
if y = 13
13 = 8x + 12
13-12 = 8x
8x = 1
x = ¹/₈ ≈ 0.125
Answer:(x+2)² + (y+1)² =9

That would make a rectangular prism with measurements of:
Length = 9
Width = 4
Height = 10
V = lwh
V = 9 * 4 * 10
V = 360
Answer: 392
Step-by-step explanation:
Le A denotes the number of students takes calculus .
and B denotes the number of students takes discrete mathematics .
Given: There are 336 students in a college who have taken a course in calculus, 227 who have take a course in discrete mathematics, and 171 who have taken a course in both calculus and discrete mathematics.
i.e. n(A)= 336 , n(B)=227
and n(A and B)=n(A∩B) =171
Using formula : n(A∪B)=n(A)+n(B)+n(A∩B)
⇒ n(A∪B)=336+227-171=392
Hence, the number of students at this college have taken a course in either calculus or discrete mathematics = 392
