Answer:
Answer choice b) 2x^4+11x^3+12x^2−10x−8
Step-by-step explanation:
(x^2+4x+2)(2x^2+3x+−4)
=(x^2)(2x^2)+(x^2)(3x)+(x^2)(−4)+(4x)(2x^2)+(4x)(3x)+(4x)(−4)+(2)(2x^2)+(2)(3x)+(2)(−4)
=2x^4+3x^3−4x^2+8x^3+12x^2−16x+4x^2+6x−8
2x^4+11x^3+12x^2−10x−8
Witch leave us with the answer choice B) 2x^4+11x^3+12x^2−10x−8
Answer:
pluto
Step-by-step explanation:
Answer: -2/3
Step-by-step explanation:
The slope intercept form of that equation is y=(3/2)x+4, so the slope is 3/2.
To find the perpendicular slope, you need to find the opposite reciprocal. The reciprocal of 3/2 is 2/3, the opposite of 2/3 is -2/3
Answer:
3 and 5/12
Step-by-step explanation:
To find how much flour you need, subtract how much sugar you need from how much total you need of sugar and flower. To do this, turn both numbers into improper fractions. This means 3 and 2/3 turns into 11/3 as there are 3 thirds per whole, and there are three wholes plus the 2 thirds, equaling 11/3. The 1/4 is already an improper fraction, so you can move on.
Now you just covert them to have the same denominator by multiply 11/3 by 4 on top and bottom and 1/4 by 3 on both the top and bottom to get 44/12 and 3/12. Now you just subtract 44/12-3/12 and get 41/12. Made into a mixed number that is 3 and 5/12.
