Which of the following shows the sum of the polynomials −3x2+3y2+4x and 4x2−4y+2? A. −3x2+3y2+4x+4x2−4y+2 B. −x2+3y2+4x−4y+2 C. x2+3y2+4x−4y+2 D. 7x2+3y2+4x+4x2−4y+2
Answers
D. 7x2+3y2+4x+4x2−4y+2 is your correct answer
-3x² + 3y² + 4x + 4x² - 4y + 2
Add like terms.
x² + 3y² + 4x - 4y + 2
So the answer is D.

Answer with explanation:
m∠9=80°
m∠5=55°
⇒∠3+∠5=180°----[e║f, and these angles are on the same side of transversal c]
→∠3+55°=180°
→∠3=180° -55°
→∠3=125°
→∠3=∠2-----[Vertically Opposite Angles]
1→→∠2=125°-----[True]
2.→→∠3=55°-----[False]
3.→→∠5=∠8=55°-----[Vertically Opposite Angles]----[True]
4.→→m∠9=m∠12=80°
m∠12=100°-----[false]
5.→→∠12 +∠14=180°-----[Lines e and f are parallel, and d is a transversal.]
→→80°+∠14=180°

By applying the knowledge of division of fractions, 12/25 divided by 4 is:
Given:
12/25 4
- Thus:
The first step is to change the division sign to multiplication, then turn 4/1 upside down.
- Multiply the denominator of both fractions and the numerators of both fractions
- Simplify further
Therefore, by applying the knowledge of division of fractions, 12/25 divided by 4 is:
Learn more here:
12/25 divided by 4/1 is the same as 12/25 multiplied by 1/4, because when dividing fractions, you must use the reciprocal of the divisor and multiply.
12/25 x 1/4 = 12/100 = 6/50 = 3/25
Your answer should be 3/25
