Answer:
B. 6x2+x+7
Step-by-step explanation:
combine like terms
3x^2+3x^2= <u>6x^2</u>
<u>x</u>
3+4=<u>7</u>
The second answer is D) it will increase 8 times
The equation of the line would be y = (1/2)x.
To find the equation of a line that is reflected through the line y = x, we just switch the x and y. Then, solve for y.
y = 2x
x = 2y
0.5x = y
The area of the trapeziod is 337.5
The answer is actually choice B. To solve for the area of a trapezoid, you would do the formula a+b/2 h.
