Answer:
A. 20
Step-by-step explanation:
- First we need find X.
- x = 7 (because we see question). f(g(7))
- Now we find g(x) = x - 3 => g(x) = 7 - 3
- Next we find f(x) = x² + x . We have f(4)
- f(4) = 4² + 4
- = 20
4x^2y(x+2)-x(xy2-3)
(4x^2y)^(x)+(4x^2y)(2)-x^2y^2+3x
4x^3y+8x^2y-x^2y^2+3x
4x^3y-x^2y^2+8x^2y+3x
This was very confusing to solve so sorry if I’m wrong.Also sorry if it’s too hard to write it.
Answer:
122/25
Step-by-step explanation:
488/100 percent means out of 100
find the lowest common multiple for 488 and 100 which is 4
divide numerator(488) and denominator(100) by 4
488÷4=122
100÷4=25
1) 1 + 4 = 5
45 dogs ÷ 5 = 9 = 1 (in terms of the ratio)
9 × 4 = 36 adult dogs.
2) In the ratio 1 : 2 : 6, the 2 = 22 cookies.
22 ÷ 2 = 11 = 1 (in terms of the ratio)
11 + (11 × 2) + (11 × 6)
11+ 22 + 66 = 99 cookies in total.
3) 3 + 2 = 5
80 ÷ 5 = 16 = 1 (in terms of the ratio)
16 × 2 = 32
32/80 = 16/40 = 2/5 (the answer)
Hope this helps!!
