Answer:
84x¹²
Step-by-step explanation:
it is this because when you multiply -7³×-3⁸= 21¹¹ which means when you times 4x you also have to add a 1 to the exponent which makes it 84x¹²
103+53=156
156/2=78
The average or mean is 78
Answer:
Length = 2x + 5
Width = x + 3
Step-by-step explanation:
Area of rectangle = length × width
Expression for area of the rectangle = 2x² + 11x + 15
Factorising the quadratic expression
2x² + 11x + 15 = 2x² + 6x + 5x + 15 = (2x² + 6x) + (5x + 15) = 2x(x + 3) +5(x + 3) = (2x + 5)(x + 3)
Length = 2x + 5
Width = x + 3
