Algebra Homework-Please Help?
1. twice the sum of y and z is increased by y
2. four times the product of x and y decreased by 2xy
3. the product of five and the square of a, increased by the sum of eight, a^2, and 4
4. three times the sum of x and y increased by twice the sum of x and y
Favorite Answer
1. 2(y+z) + y = 2y + 2z + y = 3y + 2z
2. 4xy – 2xy = 2xy
3. a squared? or the square root of a…
5a^2 + (8 + a^2 + 4) = 5a^2 + 12 + a^2 = 6a^2 + 12
4. 3(x+y) + 2(x+y) = 5(x+y) = 5x + 5y
2. 4(x)(y) – 2xy = 2xy
3. 5a^2 + 8 + a^2 + 4 = 6a^2 + 12
4. 3(x + y) + 2(x + y) = 5(x + y) = 5x + 5y
2. 4(xy)-2xy=4xy-2xy=2xy
3. (5*a^2)+(8+a^2+4)=5a^2+8+a^2+4=6a^2+12=6(a^2+2)
4. 3(x+y)+2(x+y)=3x+3y+2x+2y=5x+5y=5(x+y)
Hope this helps!
4xy – 2xy = 2xy

3(x + y) + 2(x + y) = 5x + 5y
2. 4xy-2xy
3. 5a^2+12a^2
4. 3(x+y) + 2(x+y)
