Answer:
La familia bebió:
2 botellas de 1.5 L = 2*1.5L = 3L
5 botellas de 1/4 de litro = 5*(1/4 L) = 5/4 L
4 botellas de 1/4 de litro = 4*(1/4 L) = 1 L
Sumando eso, tenemos:
3 L + (5/4) L + 1L = 4L + 5/4 L = (16/4) L + 5/4 L = (21/4) L.
21/4 Litros tomaron en total.
¿podemos directamente sumar y restar fracciones de distintos denominadores?
No, tenemos que tener el mismo denominador para sumar o restar.
i cant read the questions so sorry
Answer:
Y=5
You must first divide b (-10) by two and square it to know what you need to make a perfect square (25). You must then add or subtract the amount to make C (-13) into that number (add 38). Don't forget to do it on the other side too! (3 becomes 41) You then factor the left side. ((Y-5)^2=41) The result is your answer. (Y=5)
Answer: 14x^2-93xy+60y^2 Hope that helps!
Step-by-step explanation:
1. Expand by distributing terms
(20x-12y)(x-4y)-(3x-4y)(2x+3y)
2. Use the Foil method:(a+b)(c+d)= ac+ad+bc+bd
20x^2-80xy-12yx+48y^2-(3x-4y)(2x+3y)
3. Use the Foil method : (a+b)(c+d)= ac+ad+bc+bd
20x^2-80xy-12yx+48y^2-(6x^2+9xy-8yx-12y^2)
4. Remove parentheses 20x^2-80xy-12yx+48y^2-6x^2-9xy+ 8yx+12y^2
5. Collect like terms (20x^2-6x^2)+(-80xy-12xy-9xy+8xy)+(48y^2+12y^2)
6. Simplify.
And your answer would be 14x^2-93xy+60y^2
