Find the expression x = -7 x2 -1 / x+4

Mathematics
1 answer:
ELEN [110]3 years ago
7 0
Please confirm the question is x = (-7x^2 - 1) / (x + 4)

if that is the case, then

x * (x + 4) = -7x^2 - 1

x^2 + 4x = -7x^2 -1

8x^2 + 4x + 1 = 0

which does not have any real solution


Edit - much easier question to evaluate the expression (x^2 -1) / (x + 4) when x=-7

(-7^2 - 1) / (-7 + 4)

= (49 -1 ) / -3

= 48 / -3

= -16

What is the surface area of this right rectangular prIsm?
uranmaximum [27]

Answer:

28

Step-by-step explanation:

To find the area of a rectangle we multiply two edges together.

since we are looking for the surface area we are actually going to be finding 6 different areas and adding them together (since there are 6 sides to a rectangle)

ok so sides 1 and 2, the edges on the left and right will be equal, and then the four sides in the middle are all going to be equal

2(1x2) + 4(3x2) = 4 + 24 = 28
