Answer:
g(f(x))= (x+3)(x+3)
Step-by-step explanation:
f(x) =x² + 6x +7
g(x)= x + 2
1st Step: Substitute the x in g(x) =x + 2 by the value of f(x)
g(f(x))= (x² + 6x +7) + 2
g(f(x))= x² + 6x + 9
2nd Step: Simplify
g(f(x))= x² + 6x + 9
g(f(x))= (x+3)(x+3)
Answer:
£30
Step-by-step explanation:
Gavyn has £18 more than Alex
—› G - A = £18
—› 4u - 1u = 3u = £18
1u = £18 ÷ 3
= £6
total units = 4 + 1 = 5
5u = 5 × £6 = £30
Hello!
In a really simple way, 3 times our answer is 19. We can just divide to find it.
19/3= 6 1/3
Anyway, it might be nice to solve the equation for b. If a=6, then b has to be 1/3, but let's check.
18+3b=19
3b=1
b=1/3
Therefore, a+b= 6 1/3
I hope this helps!
