Surface area= 2(lw + lh + wh) =

2(16)16)+2(16h)+2(6h) =

2(16)(6)+32h+12h=368

Multiply and simplify: –3x2y2 • x4 –3x5y2 9x5y2 –3x6y2 –3x5y6

Contact [7]

Answer:

Multiplying and simplifying the term $-3x^2y^2 \:.\: x^4$ we get $\mathbf{-3x^6y^2}$

Option C is correct option.

Step-by-step explanation:

We need to multiply and simplify: $-3x^2y^2 \:.\: x^4$

Simplifying the term:

$-3x^2y^2 \:.\: x^4$

While multiplying, the variables with same bases are multiplied: $a^m\:.\:a^n=a^{m+n}$

In the given question only x^2 and x^4 are variables with same bases, So we get:

$=-3(x^{2+4})y^2\\=-3x^6y^2$

So, multiplying and simplifying the term $-3x^2y^2 \:.\: x^4$ we get $\mathbf{-3x^6y^2}$

Option C is correct option.

4 red bricks have a mean weight of 5kg

Elina [12.6K]

Answer: Donna is wrong. Mean weight is 7.1kg

Step-by-step explanation:

Calculate the mean for the bricks:

4 bricks have a mean weight of 5kg = 4 * 5

5 bricks have a mean weight of 9kg = 5 * 9

1 green brick is 6kg

= (4 * 5 ) + ( 5 * 9) + 6

= 71kg

Mean = 71 / (4 + 5 + 1)

= 7.1 kg
