Answer:

$area = \frac{1}{2} (base)(height) \\ area = \frac{1}{2} (35cm)(12cm) \\ area = \frac{1}{2} (420 {cm}^{2} ) \\ area = 210 \: {cm}^{2}$

I need help, please.

Usimov [2.4K]

2 rooms would be 62+42 which is 104

3 rooms would be 104+42 which is 146

4 rooms would be 146+42 which is 188

5 rooms would be 188+42 which is 230

6 rooms would be 230+42 which is 272

but these are the prices including the 20$

without the 20$ the prices would be

2 rooms is 84

3 rooms is 126

4 rooms is 168

5 rooms is 210

6 rooms is 252

What is the completely factored form of x^4y-4x^2y-5y

AnnZ [28]

Answer:

$y(x^2+1)(x^2-5)$

Step-by-step explanation:

Factor the expression by first finding a GCF. Each term has the y variable and this can be pulled out as the GCF.

$x^4y-4x^2y-5y\\y(x^4-4x^2-5)$

To further factor the expression break the polynomial into two binomials.

To factor into two binomials, find factors that multiply to -5 and add to -4.

-5 and 1 are factors and these make the binomials $(x^2+1)(x^2-5)$ .

The final factorization is $y(x^2+1)(x^2-5)$

How can you use a picture to find 3 times 2.7

Hitman42 [59]

Hope this picture helps!

<span>The 2.7 has been broken into 2 and 0.7, and then both of these parts have been multiplied by 3, giving you the two answers of 6 and 2.1 shown. Adding these two together gives you the answer of 8.1. </span>
