Answer:

3w² + 10w +8 (C)

Step-by-step explanation:

A rectangle has a length that is 3 times its width, w, in inches. The width is increased by 2 inches, and the length is increased by 4 inches. Which expression represents the area of the larger rectangle?

First, remember that the length of the first rectangle is 3 * w, or 3w.

Now, onto the second rectangle.

The width is increased by 2, so it becomes w + 2

The length is increased by 4, so it becomes 3w +4.

Area is length times width, so the area is

(w + 2)(3w + 4)

Simplify.

3w*w + 4*w + 2*3w + 2*4 =

3w² + 4w + 6w +8

3w² + 10w + 8, or C

Solve the equation for y y−5x=3

Lyrx [107]

Answer:

y = 5x + 3

Step-by-step explanation:

y - 5x = 3

add 5x to both sides to isolate y

y = 3 + 5x

rearrange to slope intercept form

y = 5x + 3

Which of the following graph represents the equation y-2=3(x-1)

pshichka [43]

Answer with explanation:

To draw the graph of linear equation of the form

y-a=m (x-b)

We will first write it in slope intercept form which is of the form

$\frac{x}{a}+\frac{y}{b}=1\\\\\rightarrow y-2=3 \times (x-1)\\\\\rightarrow y-2=3 x-3\\\\\rightarrow 3 x-y=3-2\\\\\rightarrow 3 x-y=1\\\\\rightarrow \frac{x}{\frac{1}{3}}+\frac{y}{-1}=1$

It will cut x axis and y axis at , $(\frac{1}{3},0) \text{and} (0,1)$ respectively.

As Euclid postulate States that, Unique equation of line can be Determined by two points,So join these two points.And Infinite number of points lie on a line.

You roll a six-sided number cube. Which events are mutually exclusive?

maksim [4K]

Events are mutually exclusive only if they cannot both be true.
Only C is alright.

4 is a multiple of two so it can't be right.
Same logic works for B.

And then 2 is prime so then D is out too.
