The first one is 2x-3y/2

The second one is 1/x+2

The third one is (2x-5y)/(2x+5y)

The fourth one is x^2/z^2

Please help I'm so close to being done and I don't know how to do this!!! Pls give answer but show how to do it!!!

Answer:

8y + 16

Step-by-step explanation:

The shaded area is the difference of the large and small squares.

Area of large square:

A(l) = (y + 4)²

Area of small square:

A(s) = y²

Shaded area:

A = A(l) - A(s)
A = (y + 4)² - y² = y² + 8y + 16 - y² = 8y + 16

A ball of mass 0.4 kg flies through the air at low speed, so that air resistance is negligible. What is the net force acting on

arsen [322]

Answer:

-3.92 N

Step-by-step explanation:

We are given that

Mass of ball=0.4 kg

Acceleration due to gravity= $-9.8m/s^2$

Because the ball flies against to gravity

We have to find the net force acting on the ball while it is in motion.

We know that when there is no air resistance then the net force acts on the ball is equal to weight of ball.

Net force,F =mg

Substitute the values then we get

$F=0.4(-9.8)$

$F=-3.92N$

Hence, the net force acting on the ball while it is on motion=-3.92 N

Clara has a garden that is 7 feet wide and 4 feet long she has 30 tomato plants to put in the garden each plant needs one square

ankoles [38]

A = L * W
A = 7 * 4
A = 28 sq ft....this is the area of her garden

and if each plant uses 1 sq ft, then there will be (30 - 28) = 2 plants leftover
