-2x • 3x = -6x2 (the 2 is an exponent)
4y • -7y = -28y2 (the 2 is an exponent)
-2x • -7y = 14xy
4y • 3x = 12xy
14xy + 12xy = 26xy

—> -6x2(expo) - 28y2(expo) + 26xy

Check the answer again just to be sure, it’s been a while since I’ve had algebra!

The length of tile B is about 3.87298 inches. Which mark on the tape measure is closest to 3.87298 inches? The tape measure is m
vladimir1956 [14]

Answer:

\frac{62}{16}

Step-by-step explanation:

We are given that,

Length of the tile = 3.87298 inches.

The markings on the tape are marked in \frac{1}{16} inches.

As, we see that,

\frac{64}{16} = 4 inches.

So, the required mark will be before than \frac{64}{16} mark.

Since, \frac{62}{16} = 3.875

Hence, the mark closest to 3.87298 inches is \frac{62}{16}.

What is the Domain and Range *DON'T FORGET PARENTHESES AND BRACKETS*
Anastasy [175]

Answer:

Domain: (-5,-4,-3,-2,-1,0,1,2,3,4,5)

Range: (0,1,2,3,4, -1, -2)

Step-by-step explanation:

Domain means all of the x-axis values on the graph, so for example in (-2,0), -2 would be part of the domain and 0 part of the range. Therefor, what you would do would be take all of the plots and put all x values as the domain and all y values as the range. Hope this helped!
