Answer:

5x^2 +x - 14

Step-by-step explanation:

The area of the grass left will be the area of the total of the background subtract the area of the patio.

The area of the backyard is (3x+5)(2x-1) = 6x^2 +7x - 5

The area of the patio is (x+3)(x+3) = x^2 + 6x + 9

Subtract the two areas to have the area of the leftover grass.

6x^2 + 7x - 5 - (x^2 + 6x + 9)\\5x^2 +x - 14

Which line segments are equal? How do you know?
Olenka [21]

Answer:

MQ and QP are equal, MO and OP are equal, x=2

Step-by-step explanation:

QO is a perpendicular bisector of MP meaning that Triangle MQP must be isosceles (if at least two of the following, angle bisector, median, or an altitude, coincide in a triangle, that triangle must be isosceles). In this case an altitude and median coincide in triangle MQP. This means that MQ=QP as the triangle is isosceles. And also MO=OP because QO is a median. Now solving for x, 11=4x+3, 8=4x, x=2. Hope this helps!
