The equation is Linear
Step-by-step explanation:
Answer:
you need to put the table
Step-by-step explanation:
I believe its 27.75. I wouldn't take my word for it though.
Area = length x width
Area = 3x + 5 Cm x 8 cm
Multiply each term by each term.
Area = 24x + 40 square cm
Answer:
x ≈ 1.32, x ≈ - 5.32
Step-by-step explanation:
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ±
( subtract 2 from both sides )
x = - 2 ± 
Thus
x = - 2 -
≈ - 5.32 ( to 2 dec. places )
x = - 2 +
≈ 1.32 ( to 2 dec. places )
