A polynomial is a perfect square trinomial if in form
a^2x^2-2ab+b^2
look at each
we can eliminate A and B since we have -b^2 not +b^2
look at the rest
C. 5^2b-3*5*b+3^2
nope
D. 4^2x^2-2*4*3x+3^3
yes
answe is D (factors to (4x-9)^2)
Answer:
83.82 cm^2
Step-by-step explanation:
Aquí, queremos calcular el área de un decágono dada su apotema y la longitud de su lado.
Matemáticamente;
Área de decágono = 1/2 * perímetro * apotema
Donde perímetro = 10 * s
donde s es la longitud de los lados
Entonces el área aquí sería; 1/2 * 10 (3.3) * 5.08 = 83.82 cm ^ 2
The correct answer would be x = 4
The answer would be -6 or letter B because
Answer:
60:100, 6/10, 3/5, 6 to 10, etc.
Step-by-step explanation:
