Answer:

$\sqrt{18a}$

Step-by-step explanation:

To insert the factor, you must first find its squared value, in this case, 3's squared number is 9 so..... $3=\sqrt{9}$

Now with square roots, they multiply like any other number

so you end up with $\sqrt{9}*\sqrt{2a} \\\sqrt{9*2a}\\\\\sqrt{18a}$

Use the following functions for 10–12:

Step2247 [10]

h(x) = f(x) + g(x) = $h(x) = 18.5x-16$
h(x) = g(x) – f(x) = $h(x) = 23.5x-40$
h(x) = 4g(x) = $h(x) = (84x-112)$

<u>Step-by-step explanation:</u>

Here we have , f(x) = -2.5x + 12; g(x) = 21x - 28 or $f(x) = -2.5x + 12, g(x) = 21x - 28$ .

10. Find h(x) = f(x) + g(x).

⇒ $h(x) = f(x) +g(x)$

⇒ $h(x) = ( -2.5x + 12)+( 21x - 28)$

⇒ $h(x) = ( 21x-2.5x )+( 12 - 28)$

⇒ $h(x) = 18.5x-16$

11. Find h(x) = g(x) – f(x).

⇒ $h(x) = g(x)-f(x)$

⇒ $h(x) = ( 21x - 28)-( -2.5x + 12 )$

⇒ $h(x) = ( 21x+2.5x )+( -12 - 28)$

⇒ $h(x) = 23.5x-40$

12. Find h(x) = 4g(x).

⇒ $h(x) = 4g(x)$

⇒ $h(x) = 4( 21x - 28)$

⇒ $h(x) = (84x-112)$

Mama L [17]

Answer:

total finance cost is 274064

interest in 5 year = 17568.21

creditors reduced in year 8 is 21812.87

Step-by-step explanation:

given data

cost = 500000

rate 35%

installment = 12

annual payment = 49922

to find out

the total finance cost and interest is charged in 5 year and creditors reduced in year 8

solution

we know cost is 500000 so down payment will be

payment = 35% of 500000 = 35/100 × 500000

so payment = 175000

and 12 installment purchase price is 12 × 49922

purchase price = 599064

so total finance cost is payment + purchase price - cost

finance cost = 175000 + 599064 - 500000

so total finance cost is 274064

and

we know in 1 to 12 digit sum is 78

so interest in 5 year

interest = 5/78 of total finance cost

interest = 5/78 × 274064

interest in 5 year = 17568.21

and

interest in 8 year

interest = 8/78 of total finance cost

interest = 8/78 × 274064

interest in 8 year = 28109.13

creditors reduced in year 8 = 49922- 28109.13

creditors reduced in year 8 is 21812.87
