Answer: 15h^2 + 26h -21

Step-by-step explanation:

Use the foil method. Multiply in this order

First, 5h*3h= 15h^2

outer, 5h*7 = 35h

inner, -3*3h= -9h

last, -3*7= -21

Now add them all together

15h^2 + 35h + -9h + -21

Combine like terms

15h^2 + 26h -21

Answer:

Ok:

Step-by-step explanation:

I see that you set up 90 miles = 60 mph * t, where you found out that t = 1.5. What what you needed to do was set 180 miles = 45 mph * t. This is because it is 45 mph for the <em>whole</em> trip. Then, you find that t = 4 hours. That that means that he spent 2.5 hours driving back. Then, we can do d=vt and find 90/2.5 as the speed he went home at. Which comes out to be 36 mph.

diketahui luas permukaan kubus 864 cm2. perbandingan rusuk kubus dan p balok 3 : 4 perbandingan p l dan tinggi 4:3:2 luas permuk
Kryger [21]
S2= 864/6
s = = 12 cm
p = 4/3 x 12 = 16 cm
t = 2/4 x 16 = 8 cm
l= 3/4x 16 = 12 cm

lp= 2 (pl+pt+lt)
= 2 (16 x 12 + 16 x 8 + 12 x8)
= 2 (192+128+96) = 832cm²

AveGali [126]

Answer:

52 miles per hour

Step-by-step explanation:

455 miles in 8 hr 45 min =

455 miles in 8.75 hours

\frac{455 miles}{8.75 hours} = \frac{x}{1 hour}

8.75(x) = 455(1)

\frac{8.75(x)}{8.75} = \frac{455(1)}{8.75}

x = 52
