Answers:
a) 44+3x
b) x+32
c) 2(y-4)
d) x
Step-by-step explanation:
We have the following expressions and we have to simplify them:
a) [tex]7^{2}+2^{2}-5-4+3x[/tex]
Solving the terms with exponents:
[tex]49+4-5-4+3x[/tex]
Grouping similar terms:
[tex]44+3x[/tex]
b) [tex]x+32+4-2^{2}[/tex]
Solving the term with exponent:
[tex]x+32+4-4[/tex]
Operating with algebraic sum:
[tex]x+32[/tex]
c) [tex]-y-5+y+2(2y-y)-3[/tex]
Solving inside the parenthesis:
[tex]-y-5+y+2(y)-3[/tex]
Grouping similar terms:
[tex]2y-8[/tex]
Applying common factor [tex]2[/tex]:
[tex]2(y-4)[/tex]
d) [tex]5x-3-x+3(x+1^{2})[/tex]
Solving inside the parenthesis:
[tex]5x-3-x+3(x+1)[/tex]
Operating with distributive property:
[tex]5x-3-x+3x+3[/tex]
Grouping similar terms:
[tex]x[/tex]
