Answer is C, 25. 75 doesn't go into 100 or 175 evenly, so that wouldn't work, 20 only goes into 100 evenly, and 5 goes into all of them, but it's not the greatest common factor. 25 works for all 3, and it is the greatest number that works, so it is the greatest common factor, or GCF. So it has to be C, 25.

Expression

Cloud [144]

Answer with explanation:

An algebraic expression having one term is known as a monomial.
An algebraic expression having two terms is known as binomial.
An algebraic expression having three terms is known as trinomial.

Numerical coefficient - Number written before variable in each term.
Constant - term with no variable ( only number).

Let's check the given expressions :

$3x^2$

Type - Monomial ( having one term)

Coefficient of $x^2$ = 3

Constant =0

$5a^2b^4$

Type - Monomial ( having one term)

Coefficient of $a^2b^4$ = 5

Constant =0

$2x^2 + 3x - 8$

Type - trinomial ( having 3 terms)

Coefficient of $x^2$ = 2

Coefficient of $x=3$

Constant = -8

4.) 2(x-1)+3= 2x+1

Distribute the 2, multiply the 2 by x and -1.

2*x= 2x (all you need to do is put 2 in front of x)

2*-1= -2

2x-2+3= 2x+1

Combine like terms.

2x+1=2x+1

Subtract one on both sides.

2x=2x

Divide by 2 into both sides.

x=1

We can check this by plugging it in.

2(1-1)+3= 2(1)+1
2(0)+3= 2+1
0+3=3
3=3 <== this works

I hope this helps!
