Not sure if I’m understanding this wrong but for x you can multiply the top equation by -3 to get -12x-15y=-21 and the bottom by 4 to get 12x-8y=-48.
For y you can multiply the top equation by 2 to get 8x+10y=14 and the bottom equation by 5 to get 15x-10y=-60
Answer: Carlos is correct
Step-by-step explanation:
2x^5-250x^2
The first step is to factorize out 2x^2
2x^2(x^3-125)
This can be rewritten as
2x^2(x^3-5^3),
Recall, difference if cube (a^3-b^3)
= (a-b)(a^2 +ab + b^2)
from our equation,
a= x
b = 5.
So the difference of cubes will be
2x^2[(x-5) (x^2 + 5x + 5^2)]
=2x^2[(x-5) (x^2 + 5x + 25)]
Carlos followed these steps. So he is correct. Carlos is correct because he correctly factored the GCF, identified a and b, and applied the difference of cubes method.
Amber is incorrect because 125 is equal to b3, not b.
Bernie is incorrect because x2 is not the GCF of the polynomial. The GCF is 2x^2.
Answer: 100
Step-by-step explanation:
3 x 25 = 75
4 x 25 = 100
(Answer: 120) angle EHF = 90 degrees+30 degrees=120 angle
