Answer:
1. 9x^2-24xy16y^2
2.
3.9y^2-246y+1681
4. 18x^2+54x-44
Step-by-step explanation:
1. (3x)^2-2*3x*4y+(4y)^2
9x^2-2*3x4y+(4y)^2
9x^2-24xy+(4y)^2
9x^2-24xy+16y^2
Ans: 9x^2-24xy+16y^2 the (*) are times
2. 912+31-20=923
ANS: 13*71
3. 1681-246y+9y^2
9y^2-246y+1681
ANS : 9y^2-246y+1681
4. 3x*(9*2+6x+4)-2(9*2+6x+4)
54x+18^2+12x-2(9*2+6x+4)
54x+18x^2+12x-36-12x-8
54x+18^2+12x-36-12x-8
54x+18x^2-36-8
18x^2+54x-36-8
18x^2+54x-44
Ans: 18x^2+54x-44
5. 3x*3x-3x*4+5*3x-5*4
9x^2-3x*4+5*3x-5*4
9x^2-12x+5*3x-5*4
9x^2-12x+15x-5*4
9x^2-12x+15x-20
ANS: 9x^2+3x-20
6. (31+2)(912-61+4)=28215
ANS : 3^3*5*11*19
7. 9.12-2414+1672
912/100-2414+1672
2^4*3*19/2^2*5^2 -2414+1672
2^4-2*3*19/5^2 -2414+1672
2^2*3*19/5^2 -742
(2^2*3*19)-5^2)742/5^2
(4*3*19)-25*742/5^2
228-18550/5^2
18322/5^2
8. 2713-8
2705
ANS: 5*541
Answer:
B.
Step-by-step explanation:
Answer:
2.618 in Degrees Celsius is 36.7124 Degrees Fahrenheit. 2.618 in Degrees Fahrenheit is -16.323333 Degrees Celsius.
Expression is equivalent to - 277.6.
Simplify:
-75.4+ (-63.4)−75.4+(−63.4)
-75.4 - 63.4 −75.4 − 63.4
- 277.6
In mathematics, simply or simplification is reducing the expression/fraction/problem during a simpler form. It makes the matter easy with calculations and solving.
Here are the essential steps to follow to simplify an algebraic expression:
Remove parentheses by multiplying factors.
Use exponent rules to get rid of parentheses in terms with exponents.
Combine like terms by adding coefficients.
Combine the constants.
Here's differently to explain it: The is used to refer to a specific or particular member of a group. for instance, "I just saw the foremost popular movie of the year." There are many movies, but just one particular movie is the most popular.
