Answer:

\boxed{\bold{2a^2+9ab-7b^2}}

Step By Step Explanation:

Remove Parenthesis: (a) = a

\bold{5a^2+4ab-3b^2-\left(-5ab+4b^2+3a^2\right)}

Simplify \bold{-\left(-5ab+4b^2+3a^2\right)}

\bold{5ab-4b^2-3a^2}

Rewrite Equation:

\bold{5a^2+4ab-3b^2+5ab-4b^2-3a^2}

Simplify \bold{5a^2+4ab-3b^2+5ab-4b^2-3a^2}

\bold{2a^2+9ab-7b^2}

Answer: 2a^2+9ab-7b^2

Step-by-step explanation:

The differenece is obtained by subtracting the polynomial (5a^2+4ab-3b^2) and the polynomial (-5ab+4b^2+3a^2).

Remember that:

(-)(-)=+\\(+)(+)=+\\(-)(+)=-

Then,  you need to Distribute the negative sign:

(5a^2+4ab-3b^2)-(-5ab+4b^2+3a^2)= 5a^2+4ab-3b^2+5ab-4b^2-3a^2

Now, you need to add the like terms. Then you get that the difference is:

=2a^2+9ab-7b^2

Answer:

  • c) Four times x over four equals four over four; Division Property of Equality

===========================

Given equation and steps to solve it:

  • 4(x + 1) = 8
  • 4x + 4 = 8
  • 4x + 4 - 4 = 8 - 4
  • 4x = 4
  • 4x/4 = 4/4                        <u>This is the missing step</u>
  • x = 1

All steps given above including the missing one. As we can see, we divided both sides by 4, so the justification for this step is Division Property of Equality.

Hence, the correct choice is C.

What is the slope of a line parallel to the given line?<br> -3x + 4y = 2
Crank

Step-by-step explanation:

Hey there!

The given equation is;

-3x+4y = 2

Now, from this equation;

slope(m) =  \frac{ - coeff. \: of \: x}{coeff. \: of \: y}

m =  \frac{ - ( - 3)}{4}

m =  \frac{3}{4}

As we know that the slope of line which are parallel to eachother is equal.

<u>Therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>slope </u><u>of</u><u> </u><u>the</u><u> </u><u>equation</u><u> </u><u>whi</u><u>ch</u><u> is</u><u> </u><u>para</u><u>llel</u><u> </u><u>to</u><u> the</u><u> </u><u>equation</u><u> </u><u>is</u><u> </u><u>3</u><u>/</u><u>4</u><u>.</u>

Evaluate 7C3 explain how you got your answer
Sliva [168]
Formula is

ₙCₖ = (n!)/( k!*(n-k)! )

so ₇C₃ = (7!) / (3! * (7-3)!)

and 7! = 7 * 6 * 5 * 4 * 3 * 2 * 1

= (7 * 6 * 5 * 4 * 3 * 2 * 1)/(3 * 2 * 1 * 4!)
= (7 * 6 * 5 * 4)/(4!)
= (7 * 6 * 5 * 4)/(4 * 3 * 2 * 1)
= (7 * 6 * 5 )/(6 * 1)
= (7 * 5 )/( 1)
= 35
