He didn’t combine the -5r + 4r correctly and also he didn’t multiply 4 and -5 correctly.
if you can show your work. use
F O I L method
first
outer
inner
last.
r • r = r^2
r • -5 = -5r
r• 4 = 4r
4• -5 = -20.
the final equation is
R^2 + r -20
Answer:
I'm not confident on this but:
L = 2(W + 1)
Hopefully this might help somewhat :]
L: Length
W: Width
Hello :
8000 = 8 ×1000 = 2 ^3 ×10^3 = 20 ^3
note; identity b^3 +a^3 = (a+b) (a²+b² - ab)
in this exercice : b=20
so : 8000+b^3 = (a+20)(a²+400 - 20a).... <span>Factor the following</span>
Answer:
150
Step-by-step explanation:
A=B*H/2
A=15*20/2
A=300/2
A=150
Ignore the hypotenuse btw
Responder:
300 €
Explicación paso a paso:
Dado que:
El peso del paquete de 5 kg enviado a una distancia de 60 km es de 9 €
Tomando el producto:
5 * 60 = 9 €
300 kgkm = 9 €
1 kg · km = 9/300 €
= 0,03 €
Para un paquete de 50 kg, enviado a una distancia de 200 km:
50 * 200 = 10000 kgkm
Costo de envío de paquete:
Precio por kgkm = 0,03 €
10000 * 0,03 € = 300 €
