Answer:

48,400 yd²

Step-by-step explanation:

(220+180)/2*260=52000

1/2(180)(60)=5400

So the total area is 52000+5400=57400

Basketball court=2400

Picnic area = 4200

Playground = 40x50 + 10x40=2400

2400+4200+2400=9000

57400-9000=48400

Add or Subtract to Simplify: (x5 + x3) - (6x - x3 + 6x5)

ziro4ka [17]

Answer:

$\boxed{ \bold{ \boxed{ \sf{ - 5 {x}^{5} + 2 {x}^{3} - 6x}}}}$

Step-by-step explanation:

$\sf{( {x}^{5} + {x}^{3} ) - (6x - {x}^{3} + 6 {x}^{5}) }$

When there is a ( - ) in front of an expression in parentheses , change the sign of each term.

Also, remove the parentheses

⇒ $\sf{ {x}^{5} + {x}^{3} - 6x + {x}^{3} - 6 {x}^{5} }$

Collect like terms

⇒ $\sf{ {x}^{5} - 6 {x}^{5} + {x}^{3} + {x}^{3} - 6x}$

⇒ $\sf{ - 5 {x}^{5} + 2 {x}^{3} - 6x}$

Hope I helped!

Best regards!!

A motorcycle can go 50 miles using one gallon of gas. About how many gallons of gas will be used to go 150 kilometers? (Hint: 1

gayaneshka [121]

Answer:

The answer to your question is 1.875 gallons

Step-by-step explanation:

Data

distance = 50 mi

volume of gas = 1 gal

volume for 150 km = ?

Process

1.- Convert 50 mi into kilometers

1 mile ------------------- 1.6 km

x ------------------ 150 km

x = (150 x 1)/1.6

x = 93.75 mi

2.- Calculate the gallons wasted

1 gallon ----------------- 50 mi

x ---------------- 93.75 mi

x = (93.75 x 1)/50

x = 93.75/50

x = 1.875 gallons
