Hurry ASAP!!!!! I only need help with number 6 please explain how you get the answer to! The instructions for his equation is: s
SVETLANKA909090 [29]

Answer:

-ax + 6by + 10

Step-by-step explanation:

(2ax + 3by + 5) - (3ax - 3by - 5)

Subtrahend is the value AFTER the subtraction sign.  So in this example the subtrahends enclosed in the 2nd bracket are 3by and 5.

So subtracting by changing the signs of the subtrahends:

= 2ax + 3by + 5 - 3ax + 3by + 5

Collecting like terms:

= 2ax - 3ax + 3by + 3by + 5 + 5

Combining like terms:

= -ax + 6by + 10

A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 89m long and 70m wide.
Sindrei [870]

Step One

Find the area of the rectangle

Area = L * W

Area = 89 cm * 70 cm

Area = 6230 cm^2

Step Two

What is the formula for the two end semicircles?

Two semicircles = 1 whole circle

Area of any circle = pi * r^2

Step Three

Find the area of the circle

r = the width / 2     This may not be true. You need the diagram. If the circles are drawn on the length then use r = the length / 2

r = 70/2  = 35 cm

Area of circle = pi * r^2

Area of circle = 3.14 * 35^2

Area of circle = 3846.5

Step Four

Find the total area

The total area = Area of the rectangle + area of circle

The total area = 6230 + 3846.5

The total area = 10076.5 cm^2 <<<< Answer
