First one has initial height of 12 cm and on that inicial height we add 2cm each month which can be written as 2m + 12
Second one has initial height of 10 cm and grows 3cm per month which can be written as 3m + 10
Now we just have to find those expressions in offered equations to find answer.
We can see that system of equations is:
H(m) = 12 + 2m
H(m) = 10 + 3m
or third pair.
Answer:
The top one is 1
Step-by-step explanation:
1/8 of 240= 1/8 x 240. So 1/8 of 240 is 30.

Answer:
7x² - 6x - 18
Step-by-step explanation:
7x² - 6(x + 3)
multiply with -6
7x² - 6x - (6 × 3)
evaluate
= <u>7x² - 6x - 18</u>
