The first polynomial is 5a^2b+2a^2b^2

The other polynomial is -ab^2+a^2b^2

Now to add polynomials we must add or subtract like terms

Adding them we have

(5a^2b+2a^2b^2)+(-ab^2+a^2b^2)

5a^2b+2a^2b^2-ab^2+a^2b^2

Here 2a^2b^2 $ and $ a^2b^2 $ are like terms $

So we add then

We get

5a^2b+3a^2b^2-ab^2

The addition of the polynomial is 5a^2b+3a^2b^2-ab^2

Choose the correct proportions.
cestrela7 [59]

Answer:

Options A, B and C are CORRECT PROPORTIONS

Step-by-step explanation:

Option A

3:5 = 6:10

The LHS must equal the RHS

3:5 is in it's lowest term.

6/10 will be in it's lowest term by dividing the numerator and denominator by 2.

6/10 = 3/5

Option B

3/6 and 5/10.

Diving 3/6 fractions by 3

= 1/2

Dividing 5/10 fraction by 5

= 1/2

Option C

Dividing 6/3 by 3 = 2

Dividing 10/5 by 5 = 2

Thats how you work through equivalent proportional fractions

Which expression is equivalent
RUDIKE [14]

Given expression is

\sqrt[4]{\frac{16x^{11}y^8}{81x^7y^6}}

Radical is fourth root

first we simplify the terms inside the radical

\frac{x^{11}}{x^7}=x^4

\frac{y^(8)}{y^6}=y^2

So the expression becomes

\sqrt[4]{\frac{16x^4y^2}{81}}

Now we take fourth root

\sqrt[4]{16} = 2

\sqrt[4]{81} = 3

\sqrt[4]{x^4} = x

We cannot simplify fourth root (y^2)

After simplification , expression becomes

\frac{2x\sqrt[4]{y^2}}{3}

Answer is option B

What is 4323x - 78487 = 5693<br> 25 POINTS
poizon [28]

4323x - 78487 = 5693

4323x = 5693 - 78487

4323x = -72794

x = -72794/4323

x = -16.8387694
