Question

Please help Simplify these expressions

Answer 1

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) $7^{2}+2^{2}-5-4+3x$

Solving the terms with exponents:

$49+4-5-4+3x$

Grouping similar terms:

$44+3x$

b) $x+32+4-2^{2}$

Solving the term with exponent:

$x+32+4-4$

Operating with algebraic sum:

$x+32$

c) $-y-5+y+2(2y-y)-3$

Solving inside the parenthesis:

$-y-5+y+2(y)-3$

Grouping similar terms:

$2y-8$

Applying common factor $2$:

$2(y-4)$

d) $5x-3-x+3(x+1^{2})$

Solving inside the parenthesis:

$5x-3-x+3(x+1)$

Operating with distributive property:

$5x-3-x+3x+3$

Grouping similar terms:

$x$
