Answer:52
Step-by-step explanation:
Given
one-fifth of the plants in a garden are grape tomato plant
two-ninth of the plants in the garden are cherry tomato plants
Also there are 18 grape tomato and 20 cherry tomato plants.
Let Total plants be x
Then Grape tomato plants
x=90
thus there are total of 90 plants
also grape tomato+cherry tomato=18+20=38
Thus there are 90-38=52 remaining plants.
Answer:
(x - 6)(x + 3)
x² - 6x + 3x - 18 ( factor the first/second and third/fourth terms )
= x(x - 6) + 3(x - 6) ← factor out (x - 6) from each term
= (x - 6)(x + 3)
(-4a + b – 2c) – (3a + 2b –c)
-4a+b-2c-3a-2b+c
-7a-b-c
