Use GCF to write an equivalent expression:
10y + 16
2(5y + 8)
True or False:
3y and 3x are like terms.
No; not the same variable and exponent.
Is 62 the same as 26? Why or why not?
Not the same; 6 x 6 = 36
2 x 2 x 2 x 2 x 2 x 2 = 64
The same digits are used for the expressions 52
and 25 .Compare the values using an inequality symbol.
What is: 25 < 32 OR 32 > 25
True or False:
multiplication and division are the operations that separate terms in an expression.
terms are separated by addition and subtraction
Are these two expressions equivalent?
4x + 10 and 4(x + 10)
No; if you distribute the 4, the second expression is 4x + 40, which is not the same as 4x + 10.
Simplify the expression:
10x2 + 15x - 9x2 - x + 6x2 - 13x
7x2 + x
