Answer:

(5x² + 3) - ( 2x² + 4x - 12) = 3x² - 4x + 15

Step-by-step explanation:

The given expression is

(5x² + 3) - ( 2x² + 4x - 12)

<u>To find the subtraction result</u>

(5x² + 3) - ( 2x² + 4x - 12) = 5x² + 3 - 2x² - 4x + 12

= 5x² - 2x² - 4x + 3 + 12

= 3x² - 4x + 15

Therefore the correct answer is

(5x² + 3) - ( 2x² + 4x - 12) = 3x² - 4x + 15

Answer:

Final answer is 3x^2-4x+15

Step-by-step explanation:

Given expression is (5x^2+3)-(2x^2+4x-12).

Now we need to subtract them.

We are allowed to subtract like terms only that has same variable with same exponent.

(5x^2+3)-(2x^2+4x-12)

=5x^2+3-2x^2-4x+12

=5x^2-2x^2-4x+3+12

=(5-2)x^2-4x+(3+12)

=(3)x^2-4x+(15)

=3x^2-4x+15

Hence final answer is 3x^2-4x+15

{ \qquad\qquad\huge\underline{{\sf Answer}}}

Let's solve ~

\qquad \sf  \dashrightarrow \:  \cfrac{1}{b}  + 10 =  \cfrac{9}{b}  + 7

\qquad \sf  \dashrightarrow \:  \cfrac{9}{b}  -   \cfrac{1}{b} =  10 -   7

\qquad \sf  \dashrightarrow \:  \cfrac{8}{b}   =  3

\qquad \sf  \dashrightarrow \: b =  \cfrac{8}{3}

8_murik_8 [283]

Answer:

2\frac{2}{3}

Step-by-step explanation:

1) Convert 4\frac{1}{3} to improper fraction. Use this rule: a\frac{b}{c} =\frac{ac+b}{c}.

\frac{4\times3+1}{3} -1\frac{2}{3}

2) Simplify 4 * 3 to 12.

\frac{12+1}{3}

3) Simplify 12 + 1 to 13.

\frac{13}{3} -1\frac{2}{3}

4) Convert 1\frac{2}{3}   to improper fraction. Use this rule: a\frac{b}{c} =\frac{ac+b}{c}.

\frac{13}{3} -\frac{1\times3+2}{3}

5) Simplify 1 * 3 to 3.

\frac{13}{3} -\frac{3+2}{3}

6) Simplify 3 + 2 to 5.

\frac{13}{3} -\frac{5}{3}

7) Join the denominators.

\frac{13-5}{3}

8) Simplify.

\frac{8}{3}

9) Convert to mixed fraction.

2\frac{2}{3}

(Decimal Form: 2.666667)

Thank you,
