Bella’s shoe is more or less than one yard?

Luba_88 [7]

Her shoe may be about a foot, definitely not 3 feet (a yard.) A yard length shoe does not seem average or the normal size.

Therefore, Bella's shoe is less than one yard.

Hope this helps! :)

The Johnson twins were born nine years after their older sister. This year, the product of the three siblings ages is exactly 18

KATRIN_1 [288]

Answer: The age of the twins is 10 years.

Step-by-step explanation:

Suppose the age of older sister be x

Let the age of twins sister be x-9, as they are born after 9 years.

Product of their ages be

$x(x-9)(x-9)\\\\=x(x^2-18x+81)\\\\=x^3-18x^2+81x$

Sum of their ages will be

$x+x-9+x-9\\\\=3x-18$

According to question,

$1861+3x-18=x^3-18x^2+81x\\\\x^3-18x^2+81x-3x+18-1861=0\\\\x^3-18x^2+78x-1843=0\\\\x=19$

So, Age of older sister will be 19 years.

Age of the twins will be

$19-9=10\ years$

Hence, the age of the twins is 10 years.

I get see photo. I l ow this is wrong. Can you help?

mylen [45]

Given the equation:

$y=x^2+x-4$

We will find the value of (y) when ( x = 2i )

Note: i² = -1

so, when x = 2i

$y=(2i)^2+(2i)-4$

Simplifying the answer

So,

$\begin{gathered} y=4i^2+2i-4 \\ y=4\cdot(-1)+2i-4 \\ y=-4+2i-4 \\ y=-8+2i \end{gathered}$

So, the answer will be y = -8+2i
