Your answer is correct. The question is asking about the distributive property, which multiplies a number from the outside of the parenthesis by all numbers within the parenthesis.
For example:
2(5 + 10)
(2 x 5) + (2 x 10)
10 + 20.
30.

What value goes in box A?

marishachu [46]

Step-by-step explanation:

Hello!

For this you multiply the numbers that intersect at that box

Box A 2x and 4 intersect

2x * 4 = 8x

Box B 3 and 4 intersect

3 * 4 = 12

Box C 2x and x intersect

2x * x = $2x^{2}$

Box D 3 and x intersect

3 * x = 3x

To solve this we put all these together

$2x^{2} +3x+8x+12$

Combine like terms

$2x^{2} +11x+12$

Hope this helps!

What are the domain and range of the function below?

Sonbull [250]

ANSWER

Domain:
$x \geqslant 0$

Range:
$y \leqslant 4$

EXPLANATION

The domain refers to the values of x for which the function is defined.

The least value of x is 0.

Therefore the domain is $[0,\infty]$ .

or

$x \geqslant 0$

The range refers to values of y for which x is defined.

The highest value on the y-axis that the graph can attained is 4. The function decreases without bound.

There the range is $(- \infty,4]$ .

or

$y \leqslant 4$

chickens have 2 feet, so if 6 feet belong to the chickens, there's 3 chickens, because 2x3=6.
