Answer:
d
Step-by-step explanation:
A triangular prisms' formula is: lwh = Length * Width * Height
substitute the variables
L = 21in
W = 15in
H = 17in
21*15*17
= 5,355in
The volume of the figure is: 5,355in^3
Answer:
Step-by-step explanation:
Answer:
-x
The slope-intercept equation is y = -x + 1
Step-by-step explanation:
Answer: the solutions are
x = 3 or x = - 11
Step-by-step explanation:
The given quadratic equation is expressed as
y = 2x² + 16x - 66 = 0
The equation is already in the standard form of ax² + bx + c
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 2
b = 16
c = - 66
Therefore,
x = [- 16 ± √(16² - 4 × 2 × - 66)]/2 × 2
x = [- 16 ± √(256 + 528)]/4
x = [- 16 ± √784]/4
x = (- 16 + 28)/4 or x = (- 16 - 28)/4
x = 12/4 or x = - 44/4
x = 3 or x = - 11
