Answer:

$6((x+2)(x+3))$

Step-by-step explanation:

The given expression is:

$6x^2+30x+36$

On factorising this expression, we get

= $6(x^2+5x+6)$

= $6(x^2+2x+3x+6)$

= $6(x(x+2)+3(x+2))$

= $6((x+2)(x+3))$

therefore, on factorising the given expression $6x^2+30x+36$ , we get $6((x+2)(x+3))$ .

Thus, the binomial is $6((x+2)(x+3))$ .

The graph shows how many apples Erin can pick if she maintains a constant rate. What is the linear equation for this relationshi

Ainat [17]

Answer:

The linear equation $y=50(x)$ and Erin can pick $50$ apples per hour if she maintains a constant rate.

Step-by-step explanation:

To find the linear equation of the relationship from the graph.

We have to find the coordinates .

Let say $(x,y)=(1,50)$ and $(x_1,y_1)=(2,100)$

Here $x$ variable is the time in hour and $y$ variable is the number of apples.

To find linear equation we have to find the slope (m) of the line by using point-slope form.

$m=\frac{y_1-y}{x_1-x}$

So,

$m=\frac{100-50}{2-1}=50$

The the linear equation will be.

$y=50(x)$

Number of apples Eric pick in an hour is $50$ .

By plugging the value of $x=1$ in the equation we can find the number of apples picked by Erin per hours subsequently $x=2$ for second hour.

In each hour she picks $50$ apples.

Linear equation is $y=50(x)$ and number of apples picked by Eric in an hour is $50$ .

which statement is true for the pair of fractions shown? A 4/6 is equal to 9/12. B 4/6 is less than 9/12 C 4/6 is greater than 1

Mkey [24]

To figure this out, we just need to simplify as much as we can for each problem, and then find a common denominator.

4/6 = 9/12

2/3 = 3/4

this is false

4/6 < 9/12

2/3 < 3/4

8/12 < 9/12

this is true, but let's look at the others just in case

4/6 > 10/12

2/3 > 5/6

4/6 > 5/6

this is false

It looks like C and D are the same. This means D is also false.

So B is the only true statement

Answer: B
