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
Answer:
v = 27
Step-by-step explanation:
20 = v + 9 - 16
20 = v + (9 - 16)
20 = v - 7
v = 27
Answer:
12 cm^2
Step-by-step explanation:
He saves $124.90 because $389.90 - $265.00 = 124.90 and so that is the difference in the prices which is the answer.
Answer:
244.
Step-by-step explanation:
We have been given that Allie wants to subtract 341-97 mentally. First she adds 3 to 97 to get 100. We are asked to determine Allie's next step and the difference of both numbers.
Allie's next step would be add 3 to 341 because adding same quantity to both numbers will keep the ratio same.
After adding 3 to 341 Allie would get 
.
Now, we will subtract 100 from 344 as:
Therefore, the difference of both numbers would be 244.
