Serjik [45]

Answer:

-13.5

Step-by-step explanation:

-4/3w=18

You would need to get the w by itself on one side so the easiest way to do so would be to divide both sides my -4/3.

This would give you an answer of w= -27/2 or w= -13.5

Find the error (-8x^2y^2)^2= -64x^4y^4
ExtremeBDS [4]

Answer:

(-8)^2\neq-64

Step-by-step explanation:

Using the distributive property to expand, we have

(-8x^2y^2)^2=(-8)^2(x^2)^2(y^2)^2.

Squaring each term, we have

(-8x^2y^2)^2=64x^4y^4.

The mistake was that 8^2=64, not -64. Using the fact that 8^2=64, the right answer would be

\boxed{64x^4y^4}.

Please help because I'm getting confused, and please show step by step. :(
Westkost [7]
So lets just simplify them first
1 batch = 2 3/4 so...
11/4 cups

and you need to make 3  1/2 batch so..
7/2 batch

then you just multiply it...
11/4 x 7/2 
=77/8 
=9 5/8

so you will need 9 5/8 cups

The polynomial 6st⁹ – 3s⁶t² – 6t⁷ has 3 terms and the degree of the polynomial is 10. Then the correct option is B.

<h3>What is polynomial?</h3>

A polynomial expression is an algebraic expression with variables and coefficients.

The polynomial is given below.

5s⁶t² + 6st⁹ – 8s⁶t² – 6t⁷

Then polynomial can be arranged as

⇒ 6st⁹ + 5s⁶t² – 8s⁶t² – 6t⁷

⇒ 6st⁹ – 3s⁶t² – 6t⁷

The polynomial 6st⁹ – 3s⁶t² – 6t⁷ has 3 terms and the degree of the polynomial is 10.

Then the correct option is B.
