Geometric sequence follows by multiplying by 4.
-3
-12
-48
-192
-768
-3072
-12288
-49152
-196,608
-786,432
Let's factor all four of these before we multiply.
x² - 25 We want two numbers that add to -25 and multiply to 0.
= (x+5)(x-5)
x² - 2x
Both terms are divisible by x.
= x(x-2)
x - 2unfactorable
x² + 5x
Both terms are divisible by x.
= x(x+5)
Now we have this:
Let's go ahead and multiply across.
Cancel out the (x+5) and (x-2) from the top and the bottom.
Answer:
Step-by-step explanation:
A clerk sold 70 centimeters of fabric to a customer. This clerk correctly filled out the invoice, writing:
1 point
a) 0.07 m
b) 0.070 m
c) 0.070 cm
d) 0.70 m
The clerk sold 70cm of fabrics
So, she want to filled the invoice but it length of fabrics sold must be in metre.
From metric units
100cm = 1m
Then,
70 cm = x
100cm = 1m
Cross multiply
70 cm × 1m = x × 100cm
Divide both side by 100cm
Then,
x = 70 cm × 1 m / 100cm
cm cancel out
x = 70 × 1m / 100
x = 70m / 100
x = 0.7m.
So, the correct answer is D.
To Portuguese
O funcionário vendeu 70cm de tecidos
Então, ela deseja preencher a fatura, mas o comprimento dos tecidos vendidos deve estar em metros.
De unidades métricas
100cm = 1m
Então,
70 cm = x
100cm = 1m
Multiplicação cruzada
70 cm × 1 m = x × 100 cm
Divida os dois lados por 100cm
Então,
x = 70 cm × 1 m / 100 cm
cm cancelar
x = 70 × 1m / 100
x = 70m / 100
x = 0,7 m.
Então, a resposta correta é D.
