Answer:

Liam's work is correct

Step-by-step explanation:

25 is a percent so should always write in fraction form

25/100

then you find what number multiply by 25 gives 150

which is 6, so you do the same on the bottom

which is 600

or 150 ÷ 25/100 which also gives 600

so 600 is the number

Answer:

Here, $D>0$ , hence the quadratic equation has two distinct real roots.

Step-by-step explanation:

Given quadratic equation is $6x^{2} +10x-1$ .

Let, the quadratic equation is $ax^{2} +bx+c$ [where, $a,b,c$ are the constants]

The Discriminant $(D)=b^{2}-4ac$

Case $1$ : $b^{2}-4ac>0$ , if the discriminant is greater than $0$ , it means the quadratic equation has two real distinct roots.

Case $2$ : $b^{2}-4ac$ , if the discriminant is less than $0$ , it means the quadratic equation has no real roots.

Case $3$ : $b^{2}-4ac=0$ , if the discriminants is equal to $0$ , it means the quadratic equation has two real identical roots.

Now,

we have $6x^{2} +10x-1$ , where $a=6,b=10,\ and\ c=-1$

∴ $D=b^{2}-4ac$

$=(10)^{2}-(4\times 6\times\ -1)$

$=100+24$

$= 124$

Here, $D>0$ , hence the quadratic equation has two distinct real roots.

the term relies on a product, meaning is a geometric sequence, and the product relies on a term's ordinal value to be plugged in, namely n = 7, you simply get the term by $4\cdot 3^{(7-1)}$ , when all it needs is the ordinal value to be plugged in, is called an explicit formula.
