Answer:

-35x³ - 39x² + 25x

Step-by-step explanation:

Step 1: Write out expression

(5x - 3x²) - (5x - 2)(10x + 7x²)

Step 2: Distribute/Expand

5x - 3x² - (50x² + 35x³ - 20x - 14x²)

Step 3: Combine like terms

5x - 3x² - (36x² + 35x³ - 20x)

Step 4: Distribute negative

5x - 3x² - 36x² - 35x³ + 20x

Step 5: Combine like terms

-35x³ - 39x² + 25x

the cost of running an appliance varies jointly as the number of watts used, the hours of operation, and the cost per kilo-watt

zhuklara [117]

Suppose:
C=cost
c=cost per kilo-watt hour
w=number of watts
h=number of hours
thus
C=kwhc
where:
k=constant of proportionality:
k=C/(whc)
but
C=15 when w=6000, h=10/60=1/6 hours, c=7.5 cents per kw/h
thus
k=15/(6000*1/6*7.5)
k=0.002
thus:
C=0.002(whc)
hence:
when
h=70*2=140=140/6=70/3 hours the cost will be:
C=0.002(6000*70/3*7.5)
C=2100 cents
C=$21

Find the value of x and y

velikii [3]

Answer:

2x + 20 = 3x-10

2x -3x = -20-10

-x = -30

x= 30

Checking part:

2x+20 = 2(30) +20 = 60+20 = 80

3x-10 = 3(30) - 10 = 90-10 = 80

Hence, the final answer is x = 30.
