Answer 1

Answer: No. But what I'm going to do is write in the values of 'a', 'b', and 'c' in each expression. Then all you need to do is the multiplication, and you'll have the answer to each one.

13). -2a = -2(-3)
14). 9b = 9(-4)
15). ab = (-3) (-4)

16). -3ac = (-3) (-3) (5)
17). -2c² = -2 (5²)
18). abc = (-3) (-4) (5)

Others:

1). to 7)., and 9). and 10). are all correct

8). 3(-2x) = -6x
11). -6(-3y) = 18y

12). should be negative

A plants height is 1.6 times its age. Write an equation for the situation, where h is the plants height and y is the plants age

Answers

Answer: The required equation is $h=1.6y$

Step-by-step explanation: Given that a plants height is 1.6 times its age.

We are to write an equation for the situation, where h is the plants height and y is the plants age.

The given situation can be written in equation form as follows :

$h=1.6* y\n\n\Rightarrow h=1.6y.$

Thus, the required equation is $h=1.6y$

y x 1.6 = h Because, if the height of the plant is 1.6 times its age all you have to do is multiply y by 1.6 and you'll get the height of the plant
