first, you would rearrange the equation so that like terms were next to each other.

7y - 5y - x2 + 2x2 +3x - 17x

then you would reduce the equation based on like terms

2y + x2 - 14x

then simply rearrange the equation to get the answer, which is <u>B</u>

ANEK [815]
The volume would be 0.9 x 4.2

This means it is 90% smaller

Don't forget to round the nearest tenth place. That's the first decimal, so you answer should only have 2 digits.

Answer:

392 ft²

Step-by-step explanation:

Break this area into two parts, that is, into two trapezoids.  The first trapezoid, on the left, has length 8 ft and average length (30 ft + 27 ft)/2, so its area is (8 ft)(28.5 ft) = 228 ft ².

The second trapezoid has width 8 ft and average length (19 + 22)/2 ft, or 8 ft by 20.5 ft).  The area of this part is 164 ft².

Thus, the total area is 164 ft² + 228 ft², or 392 ft²

Please I NEED HELP ASAP <br>Graph the system of equations 2x+y=5; 14+7y=35
Luden [163]
You have to put it in Y=MX+B form, so that mean you subtract the 2x in the first equation and move it to the other side of the equal sign so it will look like this Y=2X+5 and for the second equation you do the same thing and thats your answer
