Responder:
x² + 19x + 90
Explicación paso a paso:
Área del rectángulo = Base * Alto
Dado
Base = x + 10
Altura = x + 9
Área del rectángulo = (x + 10) (x + 9)
Área del rectángulo = x (x) + 9x + 10x + 9 (10)
Área del rectángulo = x² + 9x + 10x + 90
Área del rectángulo = x² + 19x + 90
La expresión que representa el área si la cifra es x² + 19x + 90

Given:
October: 8 3/8 inches
September : 60% less rain fell than in October.
This means that only 40% rain fell in September based on the amount of rain that fell in October.
8 3/8 ⇒ (8*8)+3/8 = 67/8
40% is 4/10
67/8 * 4/10 = 268/80 = 3 28/80 or 3 7/20 or 3.35
28 ÷ 2 = 14
80 ÷ 2 = 40
14 ÷ 2 = 7
40 ÷ 2 = 20
In September 3 7/20 inches or 3.35 inches of rain fell.
Answer:
Numeric expressions apply operations to numbers. For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.
