well you cant really be expecting us to answer all that, so make sure you specify exactly WHAT you want to be answered.

62. -2(x - 1) + 5x = 2(2x - 1)

...multiply -2

-2x + 2 + 5x = 2(2x - 1)

...multiply 2

-2x + 2 + 5x = 4x - 2

...simplify

3x + 2 = 4x - 2

...add 2

3x + 4 = 4x

...subtract 3x

4 = x

What is the greatest common factor of 35b^2,15b^3 and 5b?

xz_007 [3.2K]

ANSWER

The greatest common factor is 5b.

EXPLANATION

The first expression can be rewritten as

$35 {b}^{2} = 5 \times 7 \times {b}^{2}$

The second expression is rewritten as

$15 {b}^{3} = 3 \times 5 {b}^{3}$

The third expression is

$5b = 5 \times b$

The greatest common factor is the product of the least powers of the common factors.

$GCF=5 \times b = 5b$
