Mathematics
1 answer:
natali 33 [55]3 years ago
3 0

Answer:

The answer to number one is 11√17

The answer to number two is 4

Step-by-step explanation:

In number one: once you get both radicands to be equal, then you can add them. Like of it like 3x+2x. The x’s are like terms, so you can add them together.

In number two: the √5 on the top and bottom cancel out. This leaves 12/3 which is equal to 4.

tekilochka [14]

Answer:

It's Emily's class. They have 20 students while Santiago's class has 18.

Step-by-step explanation:

75%=0.75=3/4. If 3/4=15, then 1/4 =15/3=5. So 4/4=5x4=20.

2/3=12. 1/3=12/2=6. 3/3=6x3=18.

Given that f(x) = x2 + 5x – 14 and g(x) = x + 7, find (fºg)(x) and express
mel-nik [20]

Answer:

We get \mathbf{(fog)(x)=x^3+12x^2+21x-98}

Step-by-step explanation:

We are given:

f(x) = x^2 + 5x - 14 \\ g(x) = x + 7

We need to find (f o g)(x)

We know that: (fog)(x)=f(x)\times g(x)

We multiply the both terms i.e. f(x) and g(x) to get our answer.

(fog)(x)\\=f(x)\times g(x)\\=(x^2+5x-14)(x+7)\\=(x^2+5x-14)(x)+(x^2+5x-14)(7)\\=x^3+5x^2-14x+7x^2+35x-98\\Combining\:like\:terms:\\=x^3+5x^2+7x^2-14x+35x-105\\=x^3+12x^2+21x-98

So, we get \mathbf{(fog)(x)=x^3+12x^2+21x-98}
