Answer:
(12-7x)
Step-by-step explanation:
144 − 49x²
by observation, we can see that 144 = 12² and 49 = 7²
hence we can rewrite the equation
144 − 49x²
= 12² - 7²x²
= 12² - (7x)²
recall that the expression x² - y² = (x+y)(x-y)
hence,
12² - (7x)²
= (12 + 7x)(12-7x)
(12-7x) appears in the expression above, hence 12 -7x is a factor
Answer:
B
Step-by-step explanation:
3000-1000 = 2000
600-200 = + 400
40 - 20 = + 20
8 - 3 = + 5
Answer:
I'm sorry I don't have an answer but for all future math work you should download photomath on your phone it's rly good
Answer:
The value of t(x) depends on the value of x, since t is a function of x.
Step-by-step explanation:
In any function of the form "t(x)=...," the term "t(x)" represents the output value, while x represents the input value. So, the notation "t(x)=...," indicates that the value of t(x) depends on the value of x, since t is a function of x.
A number pattern would be something that just gets repeated over and over
so for this example 120+120+120=360
so the least common multiple is 120 because adding 120, three times will get you to 360
