The equation, dividend, is written below,
x³ - 7x - 6
The divisor from the given is x - 4. If we are to convert this to equation, we have x = 4. In order to determine the answer to the question above, that is the remainder for the division operation, we substitute the x's of the dividend with 4.
R = (4)³ - (7)(4) - 6 = 30
The answer is the third choice, 30.
Answer:
B. If three sides of one triangle are congruent to three sides of a second triangle then, the triangles are congruent.
Answer:
C = a² + 2ab + b²
Step-by-step explanation:
From the diagram above,
Let the dimension of the square be
A (length) = (a + b) and B (breadth) = (a + b).
Area of the square is A*B
A * B = (a + b) * (a + b)
Area = a² + ab + ab + b²
Area = a² + 2ab + b².
Therefore the expression that defines the area of the square is a² + 2ab + b².
