Answer:
7m-3x-1
10x+26
7x-12
Step-by-step explanation:
3m - 1 + 4m -3x
sum terms by the same variable:
3m+4m=7m
we have:
7m-3x-1
7(3+2x)-4x+5
apply the distributive property:
7*3+7*2x-4x+5
we have:
10x+26
3x+4(x-3)
apply the distributive property:
3x+4*x-12
we have:
7x-12
Answer with explanation:
Term--
Terms of the algebraic expression are the parts of the expression which are separated by mathematical operators.
Coefficient--
Coefficients are the multiples which are attached just before the variable in the variable term.
Constant--
The term which does not contain variable.
a)
[tex]3m-1+4m-3x[/tex]
on combining the like terms we have:
[tex]3m+4m-1-3x\\\\=7m-1-3x[/tex]
- There are three terms:
[tex]7m,1\ and\ 3x[/tex]
- Also, the coefficients are:
[tex]7\ and -3[/tex]
- and the constant term is:
[tex]-1[/tex]
b)
[tex]7(3+2x)-4x+5[/tex]
on simplifying.
[tex]=7\times 3+7\times (2x)-4x+5\\\\=21+14x-4x+5\\\\=14x-4x+21+5\\\\=10x+26[/tex]
- There are two terms:
[tex]10x\ and\ 26[/tex]
- Also, the coefficient is:
[tex]10[/tex]
- and the constant term is:
[tex]26[/tex]
c)
[tex]3x+4(x-3)[/tex]
on simplifying the given expression:
[tex]=3x+4\times x+4\times (-3)\\\\=3x+4x-12\\\\=7x-12[/tex]
- There are two terms:
[tex]7x\ and\ 12[/tex]
- Also, the coefficient is:
[tex]7[/tex]
- and the constant term is:
[tex]-12[/tex]
