Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{8 {y}^{2} + 4y - 8}}}}}$

Step-by-step explanation:

Given,

Length of a rectangular garden ( l ) = 2y - 4

Width of a rectangular garden ( w ) = 4y²

Perimeter of the garden = ?

Finding the perimeter of a rectangular garden having length of 2y-4 and width of 4y²

$\bold{ \boxed{ \sf{perimeter \: of \: a \: rectangle = 2(l + w)}}}$

$\longrightarrow{ \sf2(2y - 4 + 4 {y}^{2}})$

Distribute 2 through the parentheses

$\longrightarrow{ \sf{4y - 8 + 8 {y}^{2} }}$

Arrange it in standard form

$\longrightarrow{ \sf{8 {y}^{2} + 4y - 8}}$

Hope I helped!

Best regards! :D

Answer:

They will have to pay $5,692,500 in 90 days.

Deben pagar $5,692,500 pagar al final de un período de 90 días.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time, in years..

After t years, the total amount of money is:

$T = E + P$ .

In this question:

$P = 5500000, I = 0.14$

3 months is 3/12 = 1/4 = 0.25 of an year. So $t = 0.25$

Then the interest accrued is:

$E = P*I*t = 5500000*0.14*0.25 = 192500$

What they will have to pay:

$T = 192500 + 5500000 = 5692500$

They will have to pay $5,692,500 in 90 days.

Deben pagar $5,692,500 pagar al final de un período de 90 días.

What is the inverse of the function f(x) =2x-10

GalinKa [24]

$f(x) =2x-10 \\ y=2x-10 \\ \\ x = 2y-10 \\ 2y = x+10 \\ y= \frac{1}{2} x+5 \\ \\ \\ \boxed {f^{-1}(x)= \frac{1}{2} x+5}$

18. -4

19. 1310 ft

20. 330 ft

Step-by-step explanation:

13. 34*(-2)=-68

14. -9*(-4)=

-(9*(-4))=

-(-36)=36

15. 12*(-3)=-36

16. -12/4=-3

17. -20/(-2)=

20/2=10

18. 200/(-50)=-4

19. -1640*(-1)-(-330*(-1))=

1640-(-330*(-1))=

1640-330=1310 ft

20. -990*(-1)-(-660*(-1))=

990-(-660*(-1))=

990-660=330 ft
