Find x using completing the square method x^2+16n+28 = 0

Mathematics
1 answer:
Nezavi [6.7K]3 years ago
8 0

Answer:

x=√−16n−28 or x=−√−16n−28

Step-by-step explanation:

Step 1: Add -16n to both sides.

x2+16n+28+−16n=0+−16n

x2+28=−16n

Step 2: Add -28 to both sides.

x2+28+−28=−16n+−28

x2=−16n−28

Step 3: Take square root.

x=√−16n−28 or x=−√−16n−28

V = (1/3)(Base area of a square)(Height of the square pyramid).

V = (1/3)area^{2}hight

Area of the square

A = 7 x 7

A = 49

V = (1/3)49 x 7

V = (1/3)343

V = 114.(a repeating term)3

since we rounded

V = 114.3cm^3
