It’s basically 100 multiplied by 2 so 200
Answer:
Step-by-step explanation:
The common ratio is 3, so multiply the numbers of the pattern by 3. So 1x3 is 3, 3x3 is 9, 9x3 is 27, 27x3 is 81, 81x3 is 243, and just continue until you're on the 7th number; 1 was the first, 3 was the second and 9 was the third.
Answer: -21m+28
Step-by-step explanation:
-7(3m-4)
-7* 3m = -21m
-7*-4= 28
One method is called the ac method:-
For example factor
3x^2 + 2x - 21
ac ( first coefficient times the last) = 3*21 = -63
now we need to find 2 factors of -63 which add up to the coefficient of x ( + 2):-
+9 and - 7 look good so we can write the original expression as:-
3x^2 + 9x - 7x - 21
Factor by grouping:-
= 3x(x +3) - 7(x + 3) ( x + 3) is common so:-
= (3x - 7)(x + 3) Answer
Answer:
p = 2 and q = 14
Step-by-step explanation:
Evaluate f(g(x)) by substituting x = g(x) into f(x), that is
f(px + 4)
= 3(px + 4) + p = 3px + 12 + p
f(g(x)) = 3px + 12 + p and f(g(x)) = 6x + q
Equating the 2 expressions gives
3px + 12 + p = 6x + q
Compare the coefficients of like terms and the constant term
For the 2 expressions to be equal then
3p = 6 ⇒ p = 2 , and
q = 12 + p = 12 + 2 = 14
