Answer:
No.
Step-by-step explanation:
2(5x-3) + 6x is equal to 16x-6:
Distribute:
=(2)(5x)+(2)(−3)+6x
=10x+−6+6x
Combine Like Terms:
=10x+−6+6x
=(10x+6x)+(−6)
=16x+−6,
Which is not equal to 16x-3
Answer:
3x^2+27y^2-18xy
Step-by-step explanation:
3(x-3y)^2
3 [(x-3y)(x-3y)]
3 [x^2-3xy-3xy+9y^2]
3 [x^2-6xy+9y^2]
open d bracket
3x^2-18xy+27y^2
rearrange
3x^2+27y^2-18xy
(3^2)/3 = 3
Cube root of 9 ≈ 2.08
Square root of 9 = 3
Cube root of 27 = 3
Square root of 27 ≈ 5.2
